Will a 40A Charger run on 30A shorepower?

Question:

Is there any benefit in having a 40 amp AC charger if my shore power is 30 amps? Should I change to a 30 amp charger?

Answer:

Actually we need to differentiate between AC and DC voltage and amps.

Your 40 Amp 12 VDC charger (aka converter) is powered via 120 Volts and runs at less than 5 amps AC. The output of the charger is 40 amps at 12VDC. Therefore you can keep your 30 amp 40 120V receptacle and run your 40 amp charger no problem.
