Mike, I have a XG8000E, when running will the generator charge the battery?
Raymond 
from Connecticut 
February 12, 2014
Answer
Thanks for your inquiry.

The Generac 5747 does not charge the battery while it is running. The generator comes with a wall charger in order to maintain the battery when not in use. Below is a link to the Owner's Manual which will cover this.

I was interested in buying the Generac GP17500E. I did my homework and believe it is the one for me. The questions I have are: 1. Can I convert it to propane? 2. How long will a 15lb propane tank last on this generator if I'm not powering the whole house and just the bare necessities? Thank you Ryan

Answer
Thanks for your inquiry.

We at Power Equipment Direct do not recommend converting your gasoline portable generator to an alternative fuel and doing so will void the manufacturer’s warranty and may cause damage to the generator itself. These conversions are not recommended by any of the generator manufacturers.

Gasoline has an Ignition Point of 475–536 °F. When a generator is manufactured to run solely on gasoline these temperatures are taken into consideration and the engine components are made to handle these temperatures.

Propane (LP) has an Ignition Point of 920-1020°F and Natural Gas (NG) has an Ignition Point of 900–1500°F. These higher temperatures will cause damage over time on any “gas only” powered engine.

The following guidelines cover Honda engines (Also applies to other engine manufacturers) modified to run on fuels other than the one for which they were designed, such as converting an engine to run on propane (LP) or natural gas (NG).


• Honda gasoline engines are certified to operate on unleaded fuel with a pump octane rating of 86 or higher, containing no more than 10% ethanol (E10).

• Any change to the original configuration of a certified Honda engine is a potential violation of the Clean Air Act prohibition against tampering (40 CFR §1068.101(b)(1)). The tampering prohibition is important because poorly designed and installed modifications can increase emissions.

• The Clean Air Act prohibits anyone from removing or rendering inoperative any device or design element installed on engines in compliance with regulations. These actions are considered tampering, which carries a civil penalty up to $37,500 for each engine or equipment in violation.

• Engines converted by a third party (OEM, dealer, converter, etc.) to run on a different fuel type must be recertified with the EPA on the new fuel to comply with applicable emission standards. The third party must recertify under a new family and notify Honda to not include the modified engines in the original family.

• Converted engines to be sold for use in California must meet CARB requirements and the converter must obtain approval from CARB. EPA certificates or tampering exemptions will not satisfy the requirement for CARB certification.

• Once certified, the third party must remove the Honda emission control label and apply a compliant emission control label for the new fuel indicating the new certifying manufacturer. Honda will no longer assume any responsibility as the certifying manufacturer.

• The Honda Distributor's Limited Warranty does not extend to parts affected or damaged by the conversion to or use of fuel other than the fuel for which the engine was originally designed.


• Honda offers V-twin engines specifically designed and certified for use in LP/NG applications. The engines incorporate special design features that address the higher combustion temperatures and reduced lubrication to the valve guide area (since it is a dry fuel, not liquid). Please contact your sales representative or distributor for additional information.


Disclaimer: The guidance provided is intended for Honda dealer/distributor informational purposes only and not for the purpose of providing legal advice. You must contact the appropriate certifying agencies if you require information on how regulations apply to your specific application.

The regulations and additional information can be found at these web sites:

The run times will always vary based on the actual load put on the generator.

What are the total number of circuits it can power?
Frank 
from Pennsylvania 
October 09, 2013
Answer
Thank you for your inquiry!

The Generac XG8000E is suited to provide 33.3 amps of 240 volt power. This rating does not translate to a specific number of circuits, as there are a wide variety of circuit ratings in the marketplace.

The limiting factor on any 8kW generator is the 30 amp 4-wire 120/240v receptacle which is rated at 30amps. Any of our 30 amp manual switches will work - you would just need to focus on the number of circuits (fixed vs interchangeable) and indoor vs outdoor enclosure. The 30 amp transfer switches that we offer typically range from 6-10 circuits.

Jim, I am thinking about buying the Generac XP8000E for household emergency power after hurricane hits. I noticed the odd looking recepticles on the unit and wonder; can I plug a regular extension cord from the generator to power portable a/c unit, fridge, some lights, and maybe some other needed items? Or, can I run a 4 ton a/c with this unit, as well as my other items listed, and if so what do I need to tie into the house power panel?
Don Stewart 
from Mississippi 
August 24, 2012
Answer
Running extension cords limits the output you will get from the generator. The maximum wattage you can get out of a standard outlet is 2400 watts so the maximum you would get out of the 2 paired standard 120V outlets will be 4800 watts.

To maximize the output capacity of a portable generator it is best to connect the generator to your electrical panel using a manual transfer switch, power inlet box and a generator power cord connected to the 30A 4-prong twistlock outlet on the generator.

This will give you a maximum wattage output capacity of 7500 watts (AxV=W) and will allow you to run more equipment.

Portable generators are not designed to power central AC units due to the tremendous amount of power required to start a central AC, even when connected to a manual transfer switch.

What makes the XP8000E more expensive than the XG8000E? Looking for an 8kW for home use.
Steve Keefer 
from Maryland 
August 24, 2012
Answer
The reason the XP model costs more than the XG is because of the features and components.

The XP model is capable of delivering clean power with Generac's Truepower technology.

This is essential when powering sensitive electronics like cell phones, computers, HDTV s and any other electronics that have complex circuitry within them.

The XP also provides two high voltage 30 amp outlets. One rated for 120v and the other rated for 120/240v. The XG only has the 120/240.

What does "fully pressurized oil lubrication system " mean? Does the engine have a oil pump?
Paul 
from Ohio 
August 20, 2012
Answer
This means the unit does have an oil pump like your car and with it being fully pressurized like your car the engine will last longer as the parts are being lubricated better.

Should the chargers for the generator battery be pluged in all the time or just for a certain amount of time each month?
Paul  
from New Hampshire 
August 15, 2012
Answer
From the owner's manual page 11 (Charging the Battery):

Use battery charger plug to keep the battery charged and ready
for use. Battery charging should be done in a dry location.

1. Plug charger into “Battery Charger Input” jack, located on the
control panel. Plug wall receptacle end of the battery charger
into a 120 Volt AC wall outlet.
2. Unplug battery charger from wall outlet and control panel jack
when generator is going to be in use.

NOTE: Do not use the battery charger for more than 48 hours at one
charge.

Can you recommend a cover for the Generac XG 8000E generator?
Richard Smith 
from Connecticut 
February 26, 2012
Answer
I would recommend the Classic Accessories X-Large Generator Cover model 79547. It may be a bit longer but it would cover the width and height better than the large cover would.

Jim, I'm a licensed NH Electrician I have a Honeywell 7500Watt Portable Generator that will be used to supply selected loads in a non-separately derived residential application as outlined by the 2011 NEC. The tag on this generator indicated that the neutral is bonded to the frame. I need to know if this generator can be made into a floating neutral generator without voiding listings or warranty. If the answer is yes then where and how does the manufacture recommend the removal of the bond? And will the manufacture send a new label that indicates the generator is now a floating neutral generator. This will be an issue with any generator that has its neutral bonded to the frame portable or stationary. Any info that you can give me will be a great help. Regards, Ron T.
Ron Tasker 
from New Hampshire

Answer
Many generators that have a bonded neutral to frame can be modified so the neutral is floating, or separate from the frame and generator ground. If the neutral connection (bond) to frame can be removed, if the manufacturer supports this, it’s usually the best solution as it would result in a “floating neutral” generator and would be ideal for connecting to most transfer switches.

If the generator manufacturer does not support modifying the generator to remove the bond between neutral and ground/frame, the system can be setup to meet all codes by using a neutral switching transfer switch. A “non-separately derived system” is where the generator neutral is floating, and its neutral is always interconnected with the neutral for the utility – this is the most common way backup systems are setup – including automatic backup systems.

If you need to isolate the neutral then you need to use a GFI type transfer switch such as the Reliance Controls "X" series switches.....see link for details.

GFI Transfer Switches

Note: Typically these switches are not required unless the 120/240v outlet on the generator is GFI protected which is found on Professional generators such as the Generac "XP" models and not the "XG" model.

The fact that a generator has a bonded-neutral does not rule out compatibility with 2-pole transfer switches, which make up the majority of all transfer switches. The only time that a portable generator will not function with a 2-pole transfer switch is if the generator has a bonded-neutral AND there is a GFCI breaker or GFCI mechanism protecting the receptacle being used to connect the generator to the transfer switch. Most 120/240v generator receptacles are not GFCI protected.

National Code does not require switching the neutral in general, but arguably the neutral should be switched when using a bonded generator based on how the system is setup and defined as a whole. Any time a bonded-neutral generator is connected through a transfer switch to a house wiring system, what results are two neutral-to-ground bond points: one at the main panel and one at the generator. This can be construed as having two bond points in the electrical system, even though the portable generator is not part of the system, and therefore one of the bond points should be removed (or a transfer device implemented that isolates the neutral).

Having two bond points in this scenario creates 'dual paths' on the ground and neutral between the generator and the house panel, aka "ground loop", meaning the ground wire from the generator to the house panel will share some of the return power with the neutral wire. This leads to a very small amount of voltage on the ground wire between the generator and house panel. It can be argued by an installer or authority that this power on the ground is objectionable, and a special neutral switching setup might be mandated. This is also why if there is a GFCI breaker protecting the generator receptacle, it will sense this power being lost on the neutral (to the ground) and will trip every time the generator is connected, even under No load.

* If the generator does not have a GFCI protecting the in-use receptacle, there will not be a trip and the generator will power circuits successfully. Now it’s just a question of whether having this setup is acceptable to the home owner, installer and authority if applicable.
Using bonded generators without switching the neutral has been a common application for many years, regardless of how the code is interpreted, but about 10 years ago generators started adding GFCI's (per OSHA job site requirements) and wiring them into the larger receptacles, which will limit their applications when used at homes. The 2014 code will require new generators to have built in GFCI’s, but only on the 15/20 amp 120 volt outlets, which in most cases are not being used to power a transfer switch. If we look at all of the portable generators that are bonded neutral, and then separate the models WITH a GFCI breaker protecting the 120/240 outlet, the percentage of these generators is extremely small. These are the only generators that will functionally require a 3-pole transfer switch that breaks the neutral.

Breaking the neutral with a “3-pole” (neutral switching) transfer device eliminates the ground loop (dual paths) between the generator and house panel created by having two bond points, and will eliminate the problem of the GFCI breaker tripping creating a “separately derived system” where the generator neutral is never common with the utility neutral.

I hope this information was helpful.

I have ordered a Generac XG8000E Can I use a transfer switch rated for 30amps or due I need to use one rated 50amps ?
A Janczyk 
from Connecticut 
January 06, 2012
Answer
You will want to go with a 30A transfer switch because the largest outlet on the generator is 30A and all 30A outlets, switches, inlet boxes and cords have a maximum wattage rating of 7500 watts.

Rule of thumb is to size your generator to 80% of the generators running capacity, so when a large load kicks in the unit has enough flexibility to handle it and still provide clean voltage output.

Jim, I am looking for a portable generator 6500W - 8000W that would be safe to run electronics from. I would have tv and computers connected. Is the XG8000E recommended? Is there another? Is there recommended surge/line conditioner to use?
Kevin Guerrier 
from New Hampshire 
October 01, 2011
Answer
The most clean power will come from a Home standby unit or an inverter generator. We offer the Honda EU6500IS inverter generator that would be your safest portable option.

The Generac portables are "safe" for running electronics, but the most clean power will come from an inverter.

What is the difference between the generac 5747 and the generac 5681 besides the price? Also what is max kw and running kw on both. thanks need answer before ordering.
John Maurer 
from Illinois 
February 19, 2011
Answer
In regards to your question, the XG8000E (5747) is designed mainly for construction site use but can be used in residential applications. The GP8000E (5681) is designed for the homeowner. Both models have the exact same engine and alternator with the only difference being the frame construction and the looks. Both units offer 8,000 watts running and 10,000 watts surge capacity.


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: A certified electrician should be consulted for proper sizing and installation of any generator.

What are the outside dimensions of the Generac XP8000E generator and will it fit in a generator hard shed type cover?
Francis Gauthier 
from New York

How does this generator start in cold weather with the electric start? What is the difference between OHV engine & Generac's OHVI engine?
Daryl Hammond 
from Ohio 
January 17, 2011
Answer
Portable generators are normally stored inside and the B&S 30471 comes with a float style battery charger which is plugged into the generator when not in use. This allows the generator battery to have a sufficient charge when the generator is needed to start.

An OHV (Overhead Valve) engine is compact designed and generally makes the unit operate quieter. The Generac OHVI (Overhead Valve Industrial) engine is built robustly with premium power and high performance and comes with a fully pressurized oil lubrication system and spin-on filter.
