TP-6906 6/14 17Section 1 Installation Instructions
1.4.1 Electrical Connections
Several electrical connections must be made between
the generator set and other components of the system
for proper operation. Most field-installed accessory kits
include installation instructions. Comply with applicable
national, state, and local codes when installing a wiring
system.
For Canadian installations, refer to the Canadian
Electrical Code (CEC).
For customer-supplied wiring, select the wire
temperature rating in Figure 1-6 based upon the
following criteria:
D Select row 1 , 2, 3, or 4 if the circuit rating is
110 amperes or less or requires #1 AWG (42.4 mm
2
)
or smaller conductors.
D Select row 3 or 4 if the circuit rating is g reater than
110 amperes or requires #1 AWG (42.4 mm
2
)or
larger conductors.

* The wire size for 60_C (140_F) wire is not required to be included in the marking. If included, the wire size is based on ampacities for the
wire given in Table 310-16 of the National Electrical Coder, in ANSI/NFPA 70, and on 115% of the maximum current that the circuit carries
under rated conditions. The National Electrical Coder is a registered trademark of the National Fire Protection Association, Inc.
[ Use the larger of the following conductors: t he same size conductor as that used for the temperature test or one selected using the
guidelines in the preceding footnote.
