Labelling your switchboard

Open many switchboards and you will find labels that say "Lights 1", "Power 2", or nothing at all. Some have labels written in pen decades ago that have long since faded, or describe rooms that have been renovated out of existence. A properly labelled board is a small thing that makes a big difference when you need it.

Why it matters

• In an emergency, you can isolate the right circuit fast
• When a safety switch trips, you know which part of the house is affected
• Anyone in the house, including visitors and tenants, can use the board
• Electricians spend less time tracing circuits, which keeps jobs quicker
• If you sell, buyers and inspectors see a board that has been looked after

What good labels look like

Clear labels describe the area or appliance served, not just the circuit type. Compare:

• "Lights 1" versus "Lights: kitchen, living, hallway"
• "Power 3" versus "Power: bedrooms 2 and 3, bathroom"
• "Stove" versus "Induction cooktop"
• "Pool" versus "Pool pump and chlorinator"

Labels should be printed or written in permanent ink, sized to read easily with a torch, and fixed so they will not peel off in the heat of a meter box on a summer afternoon.

Working out which circuit is which

If your labels are missing or wrong, you can do some of the groundwork yourself, carefully.

Do

• Work in daylight with a helper
• Turn off one circuit breaker at a time and note what stops working
• Check lights, power points, and fixed appliances like the oven, hot water and air conditioner
• Write it down on a sheet of paper to give to your electrician

Do not

• Remove the switchboard cover
• Turn off circuits feeding medical equipment, aquariums or anything that cannot lose power
• Pull ceramic fuses out repeatedly if you have an older board

Remember that the fridge and freezer will be on one of these circuits, so do not leave them off for long.

When circuits do not make sense

In older homes it is common to find a circuit that runs the front bedroom, half the kitchen and the outdoor light. This is usually the result of additions over the years. It is not necessarily unsafe, but it makes faults harder to track and loads harder to manage. If your circuits are a jumble, it may be worth looking at reorganising them during a switchboard upgrade.

Labelling after new work

Any time new circuits are added, the board should be updated. When we finish a job, every circuit we touch is labelled clearly. During a full upgrade, the whole board gets new labels. See what happens during a switchboard upgrade.

Keep a copy inside

A meter box on an outside wall is not much fun to stand at on a wet winter night. Keep a copy of the circuit list inside the house too, perhaps on the inside of a kitchen cupboard door or in a drawer with the torch. Take a photo of the labelled board on your phone as well. If you rent the property out, leave a copy for the tenants and include it in the handover notes, so they are not ringing you at midnight to ask which switch runs the fridge.

Safety switches and labels

It also helps to note which circuits sit behind each safety switch. When one trips, you instantly know which circuits to check. Our guide how to reset a tripped safety switch covers what to do next.
