Electrical Connections; Generator Lead Connections - Marathon Electric MAGNAMAX Installation, Operation And Maintenance Manual

ELECTRICAL CONNECTIONS

The generator conduit box construction
allows conduit to enter the top, bottom, or
either side of the box. A hole-saw or any
suitable tool can be used to provide for the
conduit entrance. Protect the interior of the
generator from shavings when drilling or
sawing. An approved connector must be
used in conjunction with the conduit.
To minimize the transmission of vibration, it
is essential that flexible conduit be used for
all electrical cable entrance to the generator.
Refer to the connection diagram supplied
with the generator and / or the proper
diagrams shown in this section. Install all
intercomponent and external wiring in
accordance with the regulations of the
national and local electrical codes. Clean all
contact surfaces to assure good electrical
bonding with the generator lugs or bus bars.
Use heavy-duty terminal lugs or good
quality clamps for making all connections.
Insulate all connections in accordance with
national and local regulations.
Be sure the generator frame is grounded to
all the other components of the system with
a ground wire in accordance with national
and local regulations.

GENERATOR LEAD CONNECTIONS

The electrical connections in the conduit box
should be made in accordance with the
appropriate "connection diagram." Use the
diagram appropriate for the number of leads
and voltage range required. Refer to the
drawings supplied with the generator and to
drawings in this section.
The final voltage setting is established
within the selected range by an adjustment
of the voltage regulator.
CAUTION: SOME GENERATORS
HAVE MULTIPLE, IDENTICALLY
MARKED, CABLES FOR EACH LEAD.
CONNECT ALL IDENTICALLY
MARKED CABLES TOGETHER
WHEN MAKING CONNECTIONS.
