This generator will NOT WORK out of the box for home power. It is designed to work for construction jobs where requirements are different. The system has GFI protected circuits. A GFI circuit works by comparing the outgoing current on the HOT to the current coming back on the NEUTRAL. A difference of as little as 6/1000 of an amp trips the circuit. If you have the NEUTRAL and GROUND bonded at 2 points (also called a loop) the current will share the return path between the GROUND and NEUTRAL wire. Since the GFI sees less current on the NEUTRAL than on the HOT, it will trip, making the generator useless for backup. So do NOT attach the generator's ground wire to the transfer switch at all, but use a ground rod instead. This requires a professional electrician to make the change AT THE GENERATOR.
There is NO MENTION of this issue in any of the sales literature or specification. It's not in the owner;s manual, and not even in the Shop Manual, which I have a copy of. This is a SERIOUS ISSUE and Honda needs to address this, and I think they ought to fix it for free on premisis (since they are so heavy.) I am shocked (no pun intended) that this issue is not addressed by Honda. A great product rendered virtually useless for home backup without professional revision and no hint of an issue.
Response from Honda
You are correct that the EB series generators are designed for construction and industrial use. They are wired differently because they have to comply with different regulations. The owners manual does mention this (page 41).
Your local dealer can assist you with the options to make the generator work with a transfer switch. Please discuss with your local dealer so they can address your specific application.
