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...

Depending on the meter it will have 2,3 or 4 leads
If 4 leads likely one pair will be red/black, the other .. Brown or some other color.
This would be an AC meter.. Designed for 120 volt
The red lead gets a positive DC voltage, may be 12, may be 5. The black lead is DC Ground. The other leads AC, that simple.
I doubt you will find a 120 volt in that style.. You might find a 12-20 volt
Use a transformer.. I can even make a DC meter work for that job but that takes me more time to type (And many published AC-lower voltage DC diagrams exist)
