8.7 Main Power Hookup
This section describes how to hookup main
power to the CMT-130. These procedures
should be performed by a licensed electrician
that is familiar with the local electrical codes in
your area.
An adequate power supply must be provided to
the machine. See GP 6.16 Specifications for
power requirements. Power to the trimmer
should be on its own circuit with a lockable, dis-
connect switch. Too many machines on the
same circuit will reduce power to each machine.
Insufficient voltage may cause overheating, loss
of cutting/clamping force, and/or failure to oper-
ate.
The following table lists recommended wire
sizes for different voltage options. If a wire is
run over 75 feet (23 meters), the next size wire
should be used. Be sure to always follow your
local electrical codes.
