  1 Question
Q: 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.


Ron T.

by Ron Tasker from New Hampshire on January 08, 2012

A: 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.

Ready For Bad Weather
The generator was delivered very fast and arrived undamaged. Starting it was another story as I had to pull it several times without it starting. I ended up slightly pressurizing the tank to get the gas to the carburetor and once it made it there, it started right up. Maybe only putting a gallon of gas in the tank was the reason it was hard to start that first time.

It ran for an hour without an issues and powered everything I would need (furnace, well, lights, refrigerator and freezer) to... more

Generac Xg6500 Review
I recently (3 weeks ago) bought this generator because of the last two major power outages we had in New Jersey. I selected the Generac XG series because I wanted a machine that would give me reliable performance for a extended period of time. When I received the machine it was delivered in a timely fashion with no issues. I filled it with oil and put the wheels on. I put one gallon of fresh fuel in it and attempted to start it as per the instructions. It didn't want to start at all. After... more

Generac Xg6500- Terrible Gas Fumes
I recently bought a Generac XG6500(model- 5796). Filled up the oil and added about 2 gallons of gas to test it out. Took many pulls to get it started. When started, it ran fine. I put a load on it and ran it for about 15 minutes. I was happy with it. I let it cool down, then put it back in the garage. After a few hours, I noticed a strong gasoline smell from the garage coming into the house(garage is attached). I checked it out- no leaks. The smell was coming from the gas cap. Is this just a... more

Would Not Start
My generator would not start upon receipt. I have sent it to a Generac dealer, but they have yet to fix it or even tell me when I might expect it.

Very happy with my purchase from P.E.D. best price and the best availability.
I haven't had to use it in an emergency but I did start it up and made sure it was OK.
I think the problem people are having with starting this unit is the choke. I couldn't get it to start on full choke.You have to give it a few pulls on full choke then go to 3/4 or just a little in from full and she fires right up and runs like a clock.
I like the idea of the full pressure oil system.This engine should have a... more

Watch That Choke!!
I see a lot of people having trouble starting this unit. I did too. Here's the trick pull 2 or 3 times with choke fully on then push choke in half way or so. Starts right up on the next pull every time! Then push choke in all the way. Generac needs to put this in there instructions. I have used this in a power outage, ran for 11 hours on 3/4 tank of fuel. I also run the unit every month or so to keep it in shape. Love it.

Simple And Powerful
Great generator and simple to use. I ordered the generator to replace a 5500 watt system. It was delivered with days of ordering and I wanted to have it ready for any emergency.

Setup was easy and the system is small enough to store in my garage. I have hooked it into the house and can power TVs, 3 Fridges and 6 ceiling fans and light. WITH lots of power to spare.

Very happy and I would recommend this system.

Very Pleased With Generac Xg6500
This is the second XG6500 I have been around. The first has about 400 hours and is running strong. I like the pressurized lubrication system as this machine runs on the hottest days of the year in very dusty locations. The spin off oil filter is easy to change. The unit is easy to start (it takes a good pull, but we are talking about a 410 cc engine) and typically starts on the first pull. I have had off-brand units (this was purchased to replace one of those) and this starts, runs, and is... more

Easy Start
This generator starts with one pull. So many people have stated that it is hard to start. The last generator I had was electric start and keeping the battery charged was a pain and that one had no pull start.

A gas engine in good shape and well maintained will start every time and most with one pull. Some people just don't know how to start a small gas engine the right way.

Getting Ready For Nascar !!
I placed my order after a lot of research and thought it was going to be delivered 10-14 days. It was here within 5 days !!!

I read the manual and ran it for 30 minutes for the break in period. During this time I plugged in different electrical items to put generator under different loads. It's not a quite as I hoped for - but down at the camp sites at Texas Motor Speedway - there are hundreds of generators running and they are all loud - some more so than others.

I know my Generac will... more
