External DC Generator Wiring
Generator Input Circuit Breaker Kit P/N 564219 is shipped loose with the WIC. Refer to IM564219 (Kit
Installation Instructions) to install the kit into the NetSure Power System. This kit provides a 400 A circuit
breaker to feed the rectifier output bus of the power system through a shunt. The customer connects an
external generator output to this circuit breaker which then supplies generator input power to the system.

•
0 to 150 Feet: One (1) 500 kcmil or two (2) 4/0 per polarity.
•
Greater than 150 Feet: One (1) 750 kcmil per polarity.
Recommended Cable Routing
1. DC generator cables enter the WIC either via the knock outs located on the rear of the base or via the
knock outs located on the bottom of the base. See
