NEVER Back Feed A Home with Generator Power!

Electrical Question: I have a Briggs & Stratton portable generator model pro8000 01934.
I want to back feed the house and the GFCI trips.
It has the neutral bonded to the frame,and I want to float it and I can’t get any good wire schematics from Briggs,just 2 hours wasted on the phone with people who are clueless.
Where would I find the Neutral to disconnect?
Once I do, I will terminate with a connector for stand alone when needed.

This electrical wiring question came from: Dennis, a Electrician from Phillips, WI.

Thanks for your electrical wiring question Dennis.

Why Back Feeding Generator Power to a Home is Very Dangerous
Dennis, I’m sorry but I do not recommend back feeding a home with power from a generator due to the electrical dangers involved not only in the home electrical system but also the danger of back feeding the electrical utility system and creating lethal voltage for linemen who may be working on the power lines.
Additionally, I do not recommend disconnecting the built in GFCI protection that is installed in the generator unit by the manufacturer.

How to Connect a Generator to a Home
There are illegal methods of connecting a generator to a home to provide temporary power that can be very dangerous and these methods should never be used.
The proper way to connect generator power to the home electrical system is by providing a separation between the utility company power supply and the generator power so that the two sources of power can never be supplying power at the same time.
