TP-7091 2/2124 Section 3 Electrical
3.1.2 Grounding
Ground the generator set. The grounding method
must comply with NEC and local codes. Connect the
grounding cable to the generator set ground terminal in
the customer connection area. See Figure 3-3.
The requirement for having a bonded (grounded)
neutral or ungrounded neutral is determined by the type
of installation. The generator is shipped with a floating
neutral. At installation, the neutral can be grounded at
the generator set or isolated if the installation requires
an ungrounded neutral connection at the generator.
The generator set will operate properly with the neutral
either bonded to ground or isolated from ground at the
generator.
Various regulations and site configurations including the
National Electrical Code (NEC), local codes, and the
type of transfer switch used in the application determine
the grounding of the neutral at the generator. NEC
Section 250 is one example that has a very good
explanation of the neutral grounding requirements for
generators.
3.1.3 Electrical Lead Entry
Drill or punch holes in the enclosure for the electrical
conduit in the locations shown in Figure 3-2. To avoid
interference with the roof when it is open, use a 90
degree elbow at the AC voltage entry point and direct the
conduit away from the roof.
