Recommended Wiring Requirements
From Control Panel to Electric Operator
Revised: April 20, 2010
General
If your control panel was not ordered with the optional fused disconnect, it is recommended (and most likely local code) that the power source be fused immediately prior to entering the panel. Consult your local electrical codes for fusing requirements. When making penetrations in any enclosure, ensure that the components and circuitry are protected from debris and contact with tools. Use the appropriate fittings for the application/environment.
Primary Power Conduit
In all cases, Primary Power wires must be an appropriate gauge based on the amperage and length of feed to the electric operator limit box. Consult your local electrical codes.
Recommended: a minimum 14 gauge, multi-strand wire installed in a protective conduit.
Control Wire Conduit
In all cases, Control wires must be an appropriate gauge based on amperage and length of feed to the electric operator limit box. Consult your local electrical codes. Recommended: a minimum 16 gauge, multi-strand wire installed in a separate protective conduit from the Primary
Power wires.
From both conduits, an appropriate flexible conduit should bridge the wires from the wall to the electric operator. In all cases, the reversing edge wires should connect to the coil cord via an electrical junction box located at half the door opening height. Reversing edge wires are not included in the quantities below.
