Main Switchboard parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Circuit Breaker 8× Moulded-case breaker protecting a distribution feeder.
2 Copper Busbar 1× Tinned copper busbar set carrying the switchboard main current.
3 Relay 12× Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
4 Connector 40× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
5 Wire Bundle 1× Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
