I have an electrical power generator and for it to properly work with it connected to the house it must be converted from bonded neutral to floating neutral according to these instructions. I was thinking of attaching a switch to be able to easily change from bonded and floating without having to remove the cover and wire each time I want to use the generator connected to the house or when using standalone.

I haven't found a simple toggle switch that can hold the max amp and voltage. I was then thinking of an isolation switch used on cars for batteries. I've seen some that can withstand 500 amps, but at 12 DC Volts. Would that work? I want something small I can attach inside the housing. Any recommendations and what specifications I should look for?

My Generator produces a max of 50 amps at 240 AC Volts.

The bonding cable is the top right white cable. Generator Housing

  • \$\begingroup\$ @SimonB thought I could use both for extra power. I kid, of course, I have a 100 Amp Manual Transfer Switch. \$\endgroup\$
