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.
I have been using a portable generator since 1985, starting with a 1000 watt Yamaha, then a 4000 watt Generac(very load and heavy), a 2400 watt Yamaha(that was stolen last year) and now two 2000 watt Yamahas. I have never grounded any of them and have never had a problem.
