Installation
Avtron Outdoor Resistive Load Bank • Part Number K975A 994213
3-6
GROUNDING
A permanent ground conductor must be connected to the Load Bank enclosure by an individual
ground wire to prevent a potential above ground on the enclosure. There is a ground nut in the Load
Bank, located within the control compartment, for this connection. This ground conductor should be
run with the load power conductors to provide the lowest impedance fault path. The ground must be
connected to both the power source frame and to a good earth ground. The ground conductor should
be sized per the National Electrical Code Table 250.122, if not superseded by local codes.
