I've never bothered with it but the new generator I just bought has a bunch of bold warnings about wiring its ground nut but to a stake. Do you guys bother with it? 3500/4400 watt if that matters.
when I was working for the big box store I asked the repair guys about grounding. they said they know of no one who would drive a six ft rod in the ground for grounding the gen set. so I took that as a no.
