Q: Can aluminum wire be used to feed the breaker on a Generac generator?
by Glenn from New Jersey on December 11, 2014

A: Thanks for your inquiry.

When wiring the generator it must be in accordance with local jurisdiction and codes. If ALUMINUM conductors are used, apply corrosion inhibitor to conductors.

by Mike, Product Expert
Q: Are there recommended installation distances from other items? I have an AC unit near where I would like to place the generator. Also, would it be okay to be under a porch? There is about 5' from the ground to the bottom of the porch.
by Matt from Pennsylvania on June 18, 2014

A: The minimum distances can be found in the installation guide we have available on the site on the product page under the specs tab in the download document section.....

Installation Guide

The unit needs at least 3 feet clearance on the sides of the unit for proper air flow and 3 feet from the front for proper maintenance. Also, the unit requires a minimum of 5 feet clearance from the top of the unit. These units cannot be installed under a porch. These units also require a minimum of 5 feet from any window, door or ventilation opening.

We recommend you consult with your local inspector or AHJ (Authority Having Jurisdiction) for your local code requirements as they can sometimes supersede the manufacturers recommendations.

Q: I'm interested in the Generac 14 kw standby generator and I want to power it with natural gas. All your other Generac standby generators show a wattage loss of about 2kW when powered with natural gas, but this one does not show a loss in the specs I have reviewed. Is this a misprint in the specs or is this a true output? If I power it with natural gas will it deliver 12 kW or 14 kW?
by Albert Leblanc from Michigan on May 06, 2014

A: This is not a misprint in the specification. The unit will produce 14kW when operating on Natural Gas and LP as tested at the factory.

Also noted on the manufacturers specification sheets is the following....

"Maximum wattage and current are subject to and limited by such factors as fuel BTU/megajoule content, ambient temperature, altitude, engine power and condition, etc. Maximum power decreases about 3.5 percent for each 1,000 feet (304.8 meters) above sea level; and also will decrease about 1 percent for each 6° C (10° F) above 16° C (60°F)."

Specification sheets can be found on the individual product pages under the Specs tab and within the download document section.

Q: Is the housing for Generac Home Standby Generators (Model 6437) fireproof?

by Robert C. Vose III from Massachusetts on April 26, 2014

A: The following information can be found in the installation manual and the installation guide we have available on the product page under the specs tab in the download document section.....

INSTALLATION GUIDE

The National Fire Protection Association has a standard for the installation and use of stationary combustion engines. That standard is NFPA 37, its requirements limit the spacing of an enclosed generator set from a structure or wall (Figure 1.10).

NFPA 37, Section 4.1.4, Engines Located Outdoors: Engines, and their weatherproof housings if provided, that are installed outdoors shall be located at least 5ft. (1.52m) from openings in walls and at least 5ft. (1.52m) from structures having combustible walls. A minimum separation shall not be required where either of the following conditions exist:

1. The adjacent wall of the structure has a fire resistance rating of at least 1 hour.
2. The weatherproof enclosure is constructed of noncombustible materials and it has been demonstrated that a fire within the enclosure will not ignite combustible materials outside the enclosure.
Annex A — Explanatory Material
A4.1.4 (2) Means of demonstrating compliance are by means of full scale fire test or by calculation procedures.

Because of the limited spaces that are frequently available for installation, it has become apparent that exception (2) would be beneficial for many residential and commercial installations. With that in mind, the manufacturer (Generac) contracted with an independent testing laboratory to run full scale fi retests to assure that the enclosure will not ignite combustible materials outside the enclosure.

NOTE: SOUTHWEST RESEARCH INSTITUE TESTING APPROVES 18IN. (457mm) INSTALLATION MINIMUM FROM STRUCTURE. SOUTHWEST RESEARCH IS A NATIONALLY RECOGNIZED THIRD PARTY TESTING AN LISTING AGENCY.

The criteria was to determine the worst case fire scenario within the generator and to determine the ignitability of items outside the engine enclosure at various distances. The enclosure is constructed of NON-COMBUSTIBLE materials, and the results and conclusions from the independent testing lab indicated that any fire within the generator enclosure would not pose any ignition risk to nearby combustibles or structures, with or without fire service personnel response.

SOUTHWEST RESEARCH INSTITUTE DECAL (LOCATED INSIDE THE GENERATOR, NEXT TO THE GENERATOR'S DATA DECAL)

SwRI Website Link

BASED ON THIS TESTING AND THE REQUIREMENTS OF NFPA 37, SEC 4.1.4., THE GUIDELINES FOR INSTALLATION OF THE GENERATORS LISTED ARE CHANGED TO 18IN. (457mm) FROM THE BACK SIDE OF THE GENERATOR TO A STATIONALY WALL OR BUILDING. For adequate maintenance and airflow clearance, the area above the generator should be at least 5FT (1.52m) with a minimum of 3ft. (.91m) at the front and ends of the enclosure. This would include trees, shrubs and vegetation shorter than 12in. (305mm) in height. Vegetation taller than 12in. (305mm) in height must have a clearance of 60in. (1524mm). Vegetation not in compliance with these clearance parameters could obstruct air flow. In addition, exhaust fumes from the generator could inhibit plant growth. See Figure 3.1 and the installation drawing within the owner’s manual for details.

Generator exhaust contains DEADLY carbon monoxide gas. This dangerous gas can cause unconsciousness or death. Do not place the unit near windows, doors, fresh air intakes (furnaces, etc.) or any openings in the building or structure, including windows and doors of an attached garage.

Q: Can the Generac model 6438, with 200 amp transfer switch, be used in a home that has 100 amp service?
by Nicky from Maine on April 22, 2014

A: Per code it is ok to have a larger transfer switch installed in a whole house application because the switch is a pass through device only while on utility power because you are still protected by your main breaker.

However, some inspectors do not allow this and require the exact amperage size in a whole house installation.

This type of switch is installed immediately after the electric meter before your main panel allowing the generator to power your main panel just like your utility service would. As long as the generator is large enough to handle the entire electrical load at start-up.

by Mike, Product Expert
Q: Regarding the Generac 7kW fueled by Nat Gas . Spec states fuel consumption is 85 ft3/hr for 1/2 load. My question is what is this equivalent to in CCF?

by Ed from Pennsylvania on February 06, 2014

A: Natural Gas is usually measured by volume in the United States and is stated in cubic feet. A cubic foot of gas is the amount of gas needed to fill a volume of one cubic foot under set conditions of pressure and temperature.

To measure larger amounts of natural gas, "CCF" (centum cubic-feet) is used to denote 100 cubic feet, and "MCF" (mil cubic-feet) is used to denote 1,000 cubic feet.

With that said, due to the small amount of consumption you wouldn't convert the current ft3/hr to CCF.

However, if you are trying to calculate the cost in relation to therms listed by your natural gas company the conversion is 1000 ft3/hr equals 10 therms.

by Mike, Product Expert
Q: Would winter time installations of automatic generators be good or bad?

by Ron Mills from Michigan on December 30, 2013

A: You can install a generator at any time. However, it would be based on if you are putting down a concrete base as it will not set in cold temperatures. If you are putting down crushed stone or pea gravel it should be no problem.

You can also go with a GenPad (Gen Manufacturer Specific) which is a preform concrete base, so no concrete curing time. These can be installed in any temperature.

Q: I have a low pressure nat. gas line in my residence, what is the largest generator I will be able to run without doing major updates ?

by Chuck from Ohio on December 10, 2013

A: The Generac line of home standby systems can now operate on low pressure natural gas. Their low fuel pressure requirement is 3.5" to 5" of water column (1" of water column = 0.036 PSI).....0.123 PSI to 0.18 PSI. This would be for all sizes from 8kW up to 20kW.

Proper sizing of the generator is crucial to the success of any generator installation and requires a good working knowledge of electricity and its characteristics, as well as the varying requirements of the electrical equipment comprising the load.

A certified electrician needs to be consulted for proper sizing and installation of any generator.

When analyzing the electrical load, consult the manufacturer’s nameplate on each major appliance or piece of equipment to determine its starting requirements in terms of amps and voltage which can be calculated to watts using Ohms Law (Amps x Volts = Watts).

When choosing the generator output select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 8 kilowatts, select a 10 kW generator).

A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future.

Note: Applications such as commercial, all-electric homes, heat pump systems or geothermal systems require special installation procedures and a certified electrician must be contacted to evaluate and install these types of systems.

by Mike, Product Expert
Q: If I'm not around when my home standby generator is running, what type of protections systems do the Generac units have?
by Josh from New Jersey on November 13, 2013

A: The generator may have to run for long periods of time with no operator present to
monitor the engine/generator conditions. Therefore, the generator is equipped with a number of systems to automatically shut down the unit to protect it against potentially damaging conditions. Some of these systems are as follows:

• Low Oil Pressure Sensor
• High Temperature Sensor
• Overcrank Sensor
• Overspeed Sensor
• RPM Sensor
• Under-frequency Sensor
• Undervoltage Sensor
• Overvoltage Sensor
• Internal Failure Sensor
• Low Battery Voltage Alarm

The control panel contains a display which alerts the operator when a fault condition occurs. The above list is not all inclusive. For more information about alarms and control panel operation, see Section 3 (Operation) in the owner's manual.

by Mike, Product Expert
Q: What type of oil should I use in my Generac home standby generator?
by Jim from Illinois on November 11, 2013

A: The maintenance section in the Generac's home standby owner's manual lists that the oil type is based on temperature ranges specific in your area.....

SAE-30 above 32º F (0º C)
10W-30 between 40º and -10º F (4º and -23º C)
Synthetic 5W-30 for all temperature ranges

All new models come with SAE-30 oil in them and have been test run at the factory for 25 hours and no break-in is required. The first oil change would be at 2 years or 200 hours, whichever comes first.

by Mike, Product Expert
Q: I'm not sure if this falls into the repair area but, I'm concerned about the sound this generator produces. Is there a way to lower that? Is there sound proofing approved for use for the interior walls of this type of home standby? My neighbors bedroom window will be 20ft from where I plan to install the generator. I would prefer doing something inside the generator as apposed to some type of fencing or other exsternal methods.

by Mark Hernandez from New Jersey on October 23, 2013

A: The manufacturers make every effort to reduce the sound of their generators as best they can keeping within NFPA and UL requirements. There are currently no options or parts available to install inside home standby systems to reduce their db(A) levels.

Your only option is location or sound barriers installed around the unit while keeping within NFPA and manufacturers distance requirements for proper fire protection, air intake and exhaust output.

We recommend consulting with your local inspector or AHJ (Authority Having Jurisdiction) as to the specific local code requirements.

by Mike, Product Expert
Q: Is the smart Switch the actual Automatic Transfer Switch? Or are they different? The specs says that there is an automatic transfer switch included. Also, I would like to know if a bottom pad for the generator included?

by Joseph Pylilo from New York on October 21, 2013

A: The "smart switch" is the automatic transfer switch. The ATS has an internal load manager that will load shed up to 2 AC units preventing the overload of the generator at start-up.

The generator does come with a composite pad already attached to the bottom of the unit (generator base) but a permanent base is required and can be either concrete, crushed stone or pea gravel with a minimum thickness of 3 - 4 inches.

We do offer the GenPad which comes in both 3 inch and 4 inch thickness...here is the link to review their info and pricing....

Q: I have a new 2013 Generac generator and I'm wondering what oil it came with? I would like to top it off properly after the installation.

by John from New Jersey on October 18, 2013

A: The Generac 2013 automatic standby generators are shipped with a SAE 30 non-synthetic oil. If you are located in an area that receives snow, it is recommended to perform an oil and filter change to switch to a synthetic 5W-30 oil to promote proper generator operation. The cold weather kit is also recommended.

The appropriate intervals for oil changes and other maintenance items will be located in the owner’s manual in the Maintenance Schedule.

Current production models do not require any break in, so if the Maintenance Schedule in the owner's manual indicates that oil changes only need to be done every 2 years or 200 hours, you could drain the existing oil and switch to synthetic 5W-30 right away.

by Mike, Product Expert
Q: What is the recommended time frame to change the break-in oil on my Generac 20kW generator?

by Karin Green from New Jersey on August 10, 2013

A: All of the new 2013 Generac Home Standby generators have been pre-run at the factory for 25 hours. So, no break-in period is required.

by Mike, Product Expert
Q: I just purchased a 11kW generator and would like to know the max distance that I can run 1/2 inch steel pipe to my generator?

by Spencer Aucoin from Louisiana on June 27, 2013

A: The fuel pipe requirements are:

Natural Gas:

1/2" - Cannot Use
3/4" - Max 20 Feet
1" - Max 85 Feet
1-1/4" - Max 370 Feet

Liquid Propane Vapor: (Note: Pipe sizes are using a second stage regulator)

1/2" - Cannot Use
3/4" - Max 70 Feet
1" - Max 255 Feet
1-1/4" - Max 1000 Feet

Natural Gas Pressure: 3.5 - 7 Inches Of Water Column
Liquid Propane Vapor: 10 - 12 Inches Of Water Column

***A properly sized gas pipe is critical to the proper operation of the generator. The generator inlet size has no bearing on the proper gas pipe size.***
by Mike, Product Expert
Q: What is the difference between the Generac model 6051 and their new model 6438 since they are about the same size?
by Jose from Illinois on May 28, 2013

A: Generac went ahead and improved on the design, warranty and ease of installation after listening to consumer reviews and technicians.

They bumped up the warranty an additional 2 years to give it a solid 5 year overall which is one of the highest rated on the market.

They improved on the generator controller by upgrading to a new technology and moved from their very good Nexus design to the new and improved Evolution controller. This new controller has a back-lit interface with LED's that shows the generator status at a glance.

The new Evolution controller includes maintenance reminders and logs, battery condition (no guessing) and over a half-dozen additional alarms the Nexus controller did not have. This thing rocks!

They upgraded the engine to include a no choke carburetor which helps with all weather starting. They changed the fuel selector for natural gas and LP to an easy knob that is easy to access and change fuel type with ease (No tools required).

For the installers they made several changes to help with installation costs and time, minimize errors and accommodate current and future electric code interpretations by re-engineered some of the wiring connections.

With the changes to the carb and engine they were able to change the low fuel pressure rating for Natural Gas down from 5" of Water Column to 3.5" of Water Column. This will help tremendously with low fuel pressure areas in the country so the meters do not need to be changed as often.

With all of these upgrades they have performed I believe Generac's newest model is one of the best out there and comes highly recommended.

Gilbert,
We're sorry to hear you've had a negative experience. Chances are, the customer service representatives there aren't authorized to give repair advice due to liability reasons. They prefer you take it in to their certified/authorized repair shop so they can have someone who's worked with these units take a look at it and determine if it can be repaired.

By bringing it to an authorized repair location, they will more than likely cover it under warranty. Try taking it there, and feel free to contact us should you need further assistance with this process.

I am very happy with my purchase from Electric Generators Direct. They followed thru and kept me informed about ship date and delivery. Also took advantage of the pay by check option. Even thou it looked like the generator I bought was back ordered after I payed for it. They still shipped mine on time.

Generac 11kw
I'm very happy with this 11kw Generac Guardian. I could not pass up on this the price was right it runs everything that i need, and the free shipping right to my house was great. Plus no taxes.

Great deal, plus the electrician that you recommended, Steve Balyo Electric, did a great job and was very knowledgeable on how to wire up this generator. Yes i would recommend him to anyone.

Still Running Great.
I am writing this review as a follow up to my review dated 1/3/15 because what you really need to know is how does it continue to perform?

After two years our 11kw propane fired generator continues to perform with no problems. About 6 months ago after the weekly startup and test run I noticed a green/yellow light. I checked the panel and found battery needed charging. I completed the charge the warning light has not appeared again.

We have outages several times each year due to high... more

Surprise Use
Local power company programmed 1 hour outage at 2:00 AM Sunday morning, (2) days after we had unit installed. Unit started up and run perfectly (wife had to wake me up to hear it) I turned on all the appliances we had planned to use the generator for and everything worked just fine. Unit is well made. It definitely will not disturb our nearest neighbor who is 150 away.

Expectations Met
Recieved the shippment quickly and efficiently - everything was there and box was not damaged.
Great trucking company -driver went out of his way to drop the shipment close to the house.

No visible damage on carton but unit appears to have twisted since the front pannel does not sit straight - every thing is level but can see where pannel rides higher in one corner. Not enough to impact product integrity - just as long as my wife does not see the lines do not matcg up - I am okay.
