  9 Questions
Q: Can the air cooled unit operate in warm weather conditions and not overheat. We just had a 122 degree day and if the electricity had failed, would this generator be able to handle the load in the heat?
by Gene H. from California on June 27, 2016

A: Thank you for contacting us.

Generac Air-Cooled Standby Generators are tested in accordance to UL 2200 standards with an operating temperature of -20 ºF (-29 ºC) to 122 ºF for normal operating range

Please let us know if you have any other questions.

Q: Should I pour a concrete base to place this unit on or can you place on a level dirt pad?
by Jim from Iowa on September 03, 2015

A: Thank you for contacting Electric Generators Direct.

I would advise pouring a concrete base. Or I would advise looking into a GenPad.

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: What is the clearance needed on all four sides of the unit for proper operation?

by Mark C. from Connecticut on July 24, 2014

A: Page 11 of the Installation Guide shows proper installation distances according to NFPA and manufacturers recommendations. The guide is available on our site under the specs tab in the download documentation section......

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 external methods.

by Mark H. 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.

by Joseph P. 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.

Sure, when it comes to protecting your family, you’re willing to pay a premium, but there’s no reason you can’t get a good deal. The Generac 6462 earned our “best” spot because of its reasonable price and excellent transfer switch.

The 200-amp service-entrance automatic transfer switch features load shedding, which allows you to manage two centrals AC’s if the generator has enough power. When it doesn't, it keeps the essentials going and temporarily locks out the luxuries.

Great Product With Straight Forward Installation
This is the second Generac Generator that I've purchased and installed, the first being at my previous residence in Florida. The generator is well constructed, the Evolution Controller is a huge upgrade to the last Generac unit I purchased in 2005 which had no computer control (just an AUTO-MAN-OFF rocker switch) and the aluminum housing is an added bonus, especially living in a high rain area (outside Seattle, WA). Ordering and delivery were easy with the lift gate service only taking about a... more

Good Capacity But High Fuel Consumption
The Generac Guardian generators use the same amount of fuel regardless of the output. For example the 16 kW provides 66 amps while using 312 cubic feet of natural gas per hour of operation. The 22 kW provides 91 amps while consuming 281 cubic feet per hour of operation. I bought the 16 kW model as I did not understand that it would be using more fuel than the other two models, while providing less electrical capacity for my house.

Important to add up the cubic feet of gas needed for your... more

The only negative thing was in the shipping, product did not arrive when promised, after calling the trucking company we were told they had to call us back and when they did the answer was oh it didn't make the trailer.
Pros: Price, High Quality, Durable, I'd Buy It Again
Cons: shipping

Installed Without A Problem
Customer service was very good. Delivery to North Carolina was about 7 days. Trucker did excellent job of setting the generator in my driveway. I built the pad and got the building permits for the natural gas piping and electrical service. Got licensed contractors to install it for me. Smart way to go. Total cost was under $6k for generator, permits and installation.
Pros: Price, Exceeded Expectations, High Quality, I'd Buy It Again

Very Pleased So Far
The generator, transfer switch and battery arrived in good condition. Installation was finished today and it is working perfectly. Installation cost for my situation was $2200 and was completed in one day. Before purchasing a generator I suggest reading the online manual describing the location requirements. Some requirements could create some difficulties and a more costly installation.
Pros: Features, Easy To Use, Price

Excellent Product, Only One Minor Surprise
Everything seems to be of high quality and the unit works well. The only surprise was that the DTG (Direct to Ground) pad isn't attached to the housing, so when I picked up the housing with my tractor, the DTG pad stayed on the ground, making it harder to tweak the position. Had I known this in advance I would have duct-taped it to the housing first.
Pros: Features, Easy To Use, Price, High Quality
Cons: Bad Instructions, Explain DTG pad loose.

Sounds like you may have unbolted the pad from the generator when you were removing it from the pallet.
