On a related subject, it is well worth the time to take one's hand held voltmeter and check the voltage to any heavy loads on your RV, such as the AC. Test as close to the unit as it possible to ensure that the voltage is not significantly lower than at the power distribution panel. Load such as AC must be at full load for the test to be meaningful.
Regardless of whether one has a panel voltmeter for AC, one should use a hand held voltmeter to check voltage in the RV with all power loads on and compare the reading to that with all loads off. If one is seeing a difference (loss) of more than a couple of volts difference (loss), it would be worth investigation as to which section has the loss.
A high voltage drop (loss) always points to a high resistance which means heat. If the loss is over a short distance the heat could be enough to melt/burn a connection. This type of testing is an ideal item for one's semi-yearly maintenance checks to find problems before they become a failure.
Likewise, the power distri
"You will want to connect the wires near the power source (ie, near the battery or near your 120v circuit breaker box) and not at the end of a circuit which has other devices hooked to it, as those devices may pull the voltage down a little."
