Switchboard Labelling: What Inspectors Look For
Main switch wording, circuit schedules, warning labels and legibility — the labelling that keeps a switchboard inspection clean.
The non-negotiables
Every main switch labelled with the standard wording, every circuit identified against its protective device, and warning labels for multiple supplies, solar, and voltages where required. Labels must be durable and legible — marker on the escutcheon doesn't qualify.
The circuit schedule
A legible schedule inside the door, matching the as-built circuits, is the cheapest defect prevention available. Update it whenever a circuit is added; an inaccurate schedule is worse than none when someone isolates the wrong circuit.
Engraved beats stuck-on
Custom boards can ship with engraved traffolyte labels fitted — main switches, submains, metering sections — so site labelling is reduced to the final circuit schedule. It looks professional because it is.
