The electric company needs to track your electricity usage during the construction process, so temporary electric poles generally include a meter can. The utility company will install an electric meter into the meter can when the pole is ready to be energized.
Like any other electrical installation, a temporary pole needs circuit protection. This is provided by a circuit breaker, which will disconnect the power to the outlets if the current through the circuit exceeds the rating of the breaker. The circuit breaker also provides a way to manually disconnect the outlet portion of the pole, allowing for safe repairs or inspections.
The pole requires a ground fault current interrupter (GFCI) outlet because the pole will be exposed to moisture (and most likely to heavy rains) during the construction process. The outlet must also have a cover that is specifically designed for outdoor use; the GFCI circuitry can malfunction if the outlet gets excessively wet.
The temporary pole must have a safety ground. The safety ground is connected to a copper ground rod, which must be driven into the ground next to the pole. If a hot wire comes into contact with the safety ground, the resulting current will be safely discharged into the earth. Some installations may require more than one ground rod.
