Does a portable floating neutral generator exist ?

Does a portable floating neutral generator exist ? Please send link where I can buy one around 7000watts power with 30amp twist lock connection . Thanks

Usually you have to special order them factory direct from China.....

Shipping and handling not included.

Try Googling Alibaba, I think they carry them.

Yes indeed, I actuall bought one at a garage sale last summer, has 4 ft long handles and can be also used to trim trees :lol:

My Honda 5kW had a jumper. Remove the jumper to isolate the generator. See Honda's instructions.

How high will it float? At least 10’ I imagine.

Some Champions have instructions to lift the neutral too.

Yeah, but I need to know how high.

A foot or two may not be enough....

Yes...there are many generators with a floating neutral or that can be converted.

I just continuity test a generator to see if there is a "bond" to the frame.

Honda makes a series for home backup...i think the EM model line up.

The manufactures need to come out with a model that has a "switch" to convert from bonded to floating neutral. It is dangerous to use a floating gen-set for other than home backup where the generator gets the bond at the homes service. Upstream groundfault devices don't operate on groundfault without a bond in the gen-set when you want to take it to the jobsite or campground.

I have a floating neutral gen-set for my home that I plug in a cordcap that has a jumper from the neutral to ground to bond the system when I take it to the jobsite.

I agree on the switch option. Good idea on the cord cap.:thumbsup:

GFCIs still trip where there is more than 5mA flowing outside of the intended circuit path, even where the supply is ungrounded. Often the fact that the supply is ungrounded makes it impossible for that amount of current to flow. If the current does not flow, there is no shock hazard.

OK...just when I thought I understood grounding.

Could you share some of the dangers if using a portable generator at the jobsite or campground without the bond from neutral to ground?

If there is no ground reference where is current going to flow when a conductor faults to ground? Your first "fault" creates a ground reference, then the system becomes grounded. A second fault can result in hazardous voltages/currents being present, but a GFCI will respond when that happens.

While it is called a Ground Fault Circuit Interrupter, it really just compares the current on the circuit conductors and opens the circuit where the current on the circuit conductors does not sum to zero. it doesn't care where the current has gone, it just cares that it is not flowing on its intended path.

Off hand, I can't think of any.
