LOAD CONNECTION
Connect a 240/480 volt, 3-phase source to the three fused bars labeled A, B and C, located in the
customer connection access box. Cables to the Load Bank should be sized to handle the
maximum rated load according to the National Electric Code. Verify load cables, lugs, and
mounting hardware have sufficient arc over clearance to sheet metal and cover when closed.
The current can be determined by the following formula:
Line Current =
kW x 577
VOLTAGE (Line to Line)

GROUNDING
A permanent ground should be connected to the Load Bank enclosure either by a grounded
conduit or with a separate ground wire to prevent a potential above ground on the enclosure. No
internal ground connections are made to any terminal on the Load Bank.
