disconnect(s) and wire for power distribution to the multiple breaker boxes. This customer supplied
fused main disconnect is considered the service entrance point.
Due to the inrush current required by the transformers on start-up, the main disconnect may have to
be oversized or use hi-magnetic trip breakers to handle this momentary inrush current requirement.
An alternative is to shut down the individual breakers on the panelboard before turning on the main
disconnect and then turn on the panelboard breakers individually.
The following table illustrates a typical panelboard wiring list. A list similar to this is located inside
the panelboard door. The Square D 30 amp QA breaker is UL listed for 1 or 2 #10 AWG wire(s).
