EXTERNAL ELECTRICAL CONNECTIONS
1. Electrical Connections to the generator are to be made inside
the main output circuit breaker panel. The connections will
consist of the following:
• 2 x Ungrounded conductors – Minimum wire size use 75
Deg C, 300V wire, 10AWG Copper.
• 1 x Grounded Conductor - Minimum wire size use 75 Deg
C, 300V wire, 10AWG Copper.
• 1 x Equipment Grounding Conductor - Minimum wire size
use 75 Deg C, 300V wire, 10AWG Copper.
• 6 x Control Wires – Use 75 Deg C, 300V wire, 14AWG
Copper.
NOTE:
Either use different colored wires or identify both ends of the
wires for easy connection of all wires to the Transfer Switch.
NOTE:
Local codes may require the control wires to be run in a sepa-
rate conduit than the power wires.
• Use Class 1 wiring methods.
• These conductors should be fed through ¾” Flexible Liquid-
tight conduit for easy connection to the generator.
2. Remove the dead front plate from the output circuit breaker
panel. Retain fastener and external tooth washer for
reassembly.
3. Remove the conduit connector plate from the output circuit
breaker panel. Remove the plastic hole plug from the conduit
connector plate.
4. Pass all wires through hole in conduit connector plate, insert
conduit connector, and place lock nut onto conduit connector.
Fully tighten locknut.
5. Support the conduit connector plate up towards the output
circuit breaker. Make all the required wiring connections to the
Circuit breaker, Neutral Bar, Ground bar and Terminal strips
as described on the decal on the back side of the dead front
plate.
NOTE:
In order to maintain separation of circuits, the DC control wires
must be separated from the AC control wires. A piece of fiber-
glass sleeving has been provided in the manual kit to achieve
this. Slide the sleeving over the AC wires OR the DC wires, but
not both. Sleeving should extend over the wires from the conduit
connector in the conduit plate up to the terminal blocks.
6. Once all connections are made, reattach the conduit
connector plate to the output circuit breaker panel making
sure no wires are trapped behind the panel.
