I have a West Marine 1000 Watt inverter that I wired to a few outlets with no apparent ill effects. I use a shore power sensing relay I got from West to switch them between inverter and shore power. I used a GFCI outlet and it works when I test it. I have not tested a neutral>ground leak, maybe I should? The relay switches both hot and neutral wires and the green wire stays common. So far the biggest shock danger I have found with inverters is people assuming the shore power cord being disconnected = no AC power anywhere.

David, I've followed some of this thread and have a few concerns where some have mentioned using an inexpensive inverter. Using an inverter that is not intended for marine use or not properly grounded can cause problems. An inverter can produce short duration spikes which exceed the insulation rating of most wires. This becomes an issue in wet areas and will cause insulation failure. There are other issues relating to inducing corrosion. A friend who coincidentally keeps his boat in RI and is the technical support guru for a company that sells variable frequency drives (inverters for AC motors) had to replace his propellers when he used an inverter he bought from Harbor Freight. It was probably fine for anything other than marine use. If the neutral on the inverter is not grounded, the neutral can kill you regardless of the presence of a GFCI.

It does not have power outputs but two receptacles for plugs. I believe I can wire an extension cord to a outlet (assuming adequately rated and quality components), but I would like to know of any pitfalls that others may have found. Thanks in advance. David F.
