If you are worried about ground in a boat, neg. side battery and motor ground. That's if you run your outboard to battery .
If you don't, no grounding needed.
Portable generators need no ground on boats.
Ac 110 at home should have a ground rod to expend elect. current for grounding.
Even with a grounding rod you should have a surge protector on you Elect. panel to prevent high voltage to destroy your appliances and putters.
If your home has a surge protector you must enter your generator before it, usually a outside box breaker 100-200 amps.
Depends on the wattage of generator, if using a 5000-10000 watt gen. a 50amp breaker is fine.
Homes with surge protection keeps all your electrical appliances protected, why in hooking up generators you go before this protection to filter any surge.
Most people like i have for more than 5 days without elect during Charley or Andrew used small generators 1200-5000 watts to power refig. fan and light and tv with 1800 watt gen. these items were pluged into extension cord direct to gen. require no surge protection.
You can and advise to just get a surge cable to plug in for these appliances and computer, cost is around $18.
I have recent bought a 14x7 ft cargo trailer that I converted into a camper that is 6ft-6 inches high and haul two full size motorcycles and two 12ft kaycks. has refig. top loading, two burner stove, double sink, ice maker.
Also all is run on DC and AC complete separated. 5 Gal. Porta Potty with on demand hot water for showers outside camper with full enclosed curtain.
When we get a campsite we take out the motorcycles and kayacs (they have wheels) and have the camper to enjoy. We do have
two gravity chairs that can sleep 2 but also have the blow up low double bed.
We also added ice maker and the 5000 btu aircondition works great in 90 degree heat in sw florida.
Think I can have my cake and eat it to except no Sailboat to tow.
The Powerhorse 2000 powers all and a 900watt microwave, twin 29 group batteries run the DC with 10 amp auto charge.
The 5000 btu runs at 4amps max. edgestar 63 quart at 1.5 amps , ice maker edgestar 1.2 amps, I haven't run the 900 watt microwave yet with the 2000 and may have to turn off AC for 2-3 min. to run it.
My built in ac is rated a 30 amps and powers everything when hooked up to campsite with 20amps or greater.
Have a 13 gal. gray water tank and a 12 gal. portable tank. Fresh water to sink in elect. pump with a hand pump next to it.
Filter system runs on the selfpriming faucet.
Most of this is same as I used on the MacX except the elect. sink pump, gray water tank and Icemaker.

When I use the generator at home I can easily attach a ground wire to the ground terminal and then to a metal stake in the ground. However, what does one do while on the water to ground it? Run a ground wire into the lake?
