The AWG wire size for the electrical service depends on the distance
of the operator from the breaker panel. Refer to the table below to
determine the correct wire size. The NOMINAL column is the ideal
distance from the breaker panel to the operator for a given wire size.
The distances shown in the MAXIMUM column should never be
exceeded. For distances greater than 3200', it is recommended that
your local utility be contacted to install a service feeder for the
installation.
Wiring from external controls such as guard shack, telephone entry,
keypad or card reader systems should be brought to the operator by a
conduit separate from the 115 VAC electrical hookup. Low voltage
control wires MUST NEVER be routed in the same conduit as A.C.
power wires. Always consult and follow all local electrical codes.
