Where is the load side of an electric meter wired?
The load side of the electric meter, which carries power to the main service panel, can be wired either directly to the panel or to an interim disconnect. To do this, the ends of the two hot load wires are stripped and connected to the bottom two load terminals on the meter's hot bus bars.
How many hot wires are in a meter box?
Three large-gauge stranded wires (two hot wires and one neutral) enter the meter box from a weather head on a metal mast (or from underground service) and are attached to the corresponding line terminals on the hot and neutral bus bars in the meter box. These feeder wires are known as the line wires.

Can you ground a voltmeter?
It is perfectly safe to test these circuits. If you can't find a good ground wire, or don't wish to tap into a ground wire, you can ground the voltmeter to the metal chassis with a self-tapping sheet-metal screw. Attach the voltmeter negative to the ground wire with a wire tap, or to the metal chassis using a screw and drill.
Can a voltmeter be used as a back light?
Aftermarket voltmeters can come with a number of options, not least of which being a back-light for night running. These lights are often stand-alone, requiring their own ground and power supply. The smart thing with these is to ground them to the chassis, and tap into the dashboard light power wire.
How to read a voltmeter?
1. Find a voltage scale on the needle's dial. Choose one that matches the setting you chose on your voltmeter's knob. If there is no exact match, read from a scale that's an easy multiple of the setting. For example, if your voltmeter is set to DC 10V, look for a DC scale with a max reading of 10.
How to test voltage?
