A load bus is defined as one or more panels protected by a single circuit breaker or fuse at the
battery plant. Cable from the battery plant is terminated at Load Shunt Bus Details rated for 800
amperes. (Two 750 kcmil feeder cables are required per shunt for currents larger than 500 amps per
shunt.) 3/8 inch hardware is provided for this connection. The cabinet may be equipped for 2, 4 or 6
loads. In 2 or 4 load configurations a bus bar link connects some panels together vertically. The 800
ampere capacity per load bus applies even if multiple fuse panels are connected together.
When internal return buses are ordered, load return bus details will be located either at the top or
the bottom of the cabinet as shown depending on if a top cable feed or bottom cable feed was
ordered. These may easily be unbolted and moved if the application requires. 3/8 inch hardware is
provided for load return cables.
Note: All bus bars are copper with a bright tin finish.
Bus bars do not require buffing or the application of NO-OX before connection to terminal
lugs or other bus bars.
