Gate Operator Power Requirement Estimates:

• High Voltage (120V) Gate Operators draw about 6 Amps per operator when in use.
• Gate Operators using batteries as the main power source draw about 2 Amps for the charging circuit.
• These estimates include accessories usage such as Keypads, Radio Remotes, and Loops but DO NOT INCLUDE lighting.
• For accurate power requirements, consult the manual or specification sheet for your operator and accessories.

 

Electrical Supply Wire Used in Driveway Gate Installations:

• Wire used in underground conduit should have a “W” in it designation, which stands for “Wet” Ex: THWN, or THHN/THWN.
• Romex CANNOT be installed in conduit, however; Romex with “UF” (Underground Feeder) designation can be used for direct burial applications.
