questions about shore power

[NRR]

If the voltage at an inside outlet measures 120 volts + or minus 10 % while the AC is running you are fine.

I know my camper with fridge on AC power and the air conditioner (13000 btu) running shows 114 volts inside. The external cable is a yellow extension cord with ten gauge wires. It is plugged into a 20A outlet. Never had a problem.

Now if your sump pump kicks in and trips the breaker. That would be a problem.

How big is your air conditioner?

Thanks to all. I am currently on a 30 circuit and I plan on running a 30 amp circuit at my home.

The voltage at an inside outlet may be greater than the voltage the air conditioner is seeing.

However if the AC voltage at the air conditioner ALWAYS measures 120 volts, (+ or minus 10 %), WHILE THE AIR CONDITIONER IS STARTING and RUNNING the air conditioner will be fine.

the meters just plugs in and test voltage where ever you go.

The OP mentioned installing the 30A plug 50-80ft. from his house. To do this he will need to run 8g wire to have approx. 120V @ 30A service.
