Each circuit in a secondary distribution box should have a unique identification number that corresponds to the panelboard and the specific breaker or fuse it feeds. This numbering system helps avoid confusion during maintenance, troubleshooting, and future expansions. Typically, the primary side refers to the incoming energy source, while the secondary side refers to the outgoing circuits supplying loads . Labels should include:
Electrical drawings and wiring diagrams use standardized symbols to represent components in the distribution box. Common symbols include:
