How to install a temporary electric meter

Updated February 21, 2017

Temporary electric meters at construction building sites allow workers to run their power tools. Connecting the feed wires to temporary meter boxes before the electric company turns on the power is the safest way to proceed. The electric company then will install a temporary meter. If you have an electrician on the job, already being paid, why spend extra money. With permanent meters, there is a disconnect fee and a reconnect fee that must be paid prior to installation.

Look for the feeder wires from the service pole.

Pull the feeder wires to the top of the meter box. The top of the box is the line side.

Strip the feeder wires down about a half inch. There are three wires, two blacks ones that are hot and one neutral one with white tape around it.

Insert the two hot wires into the cable clamp on the top of the meter, and connect them to the screw terminals. Use a screwdriver to tighten the terminal screws.

Slide the neutral wire into the connector in the middle of the meter, and tighten the screws with a screwdriver.


Have the electric company come out to the construction site and check your wiring for safety reasons.


Do not install a temporary meter on the construction site after the electrical company has already turned on the power. The current is 440 volts and will kill you.
