Hey guys and gals.
We bought a small office trailer that is wired up. It's never seen mains power and uses a generator disconnect (220). I read up on the myriad of code situations for bonding and then grounding, neutral switching etc. and came to the conclusion this would fall under separately derived system. So I verified the main panel and all interior wiring was unbonded with my meter and made sure the generator itself was neutral bonded. Following that I attached the only ground to the ground lug on the generator approx. 30 feet away to a ground rod I sunk.
Does any of that sound correct? I'm a little unsure what's meant by first point of disconnect, is that the switch or the generator itself? It's a standard cord and plug unit using a L14-30p.
Thanks
Edit: I also changed out the 50 amp main breaker for a 30 amp, since it's a 30 amp unit.
