How to wire a voltmeter?
I'm thinking of installing something similar to this to monitor the AC power in our new trailer. I don't want the 'plug in' type. Would rather have a small permanently mounted hardwired panel. Ques...

Resistance i.e. voltage drop "should be" almost non-existent in an RV chassis AC voltage system. This excludes the pedestal connector wire and plug. And ideally that too should also be tiny. There is no reason on the face of the earth to suffer alternating current voltage drop within a rig. Of course all circuits should be periodically tested. I test receptacles with an 1,875 watt heater, and roof air connections with a voltmeter, starting the unit on high head pressure.
