Switchboard inspection for faults and extra load
A new appliance may raise questions about the board and existing circuits. An inspection can check their condition and the proposed load. It helps separate a repair from an upgrade, so the quote fits the work you need.
What would an upgrade change?
- Condition of the board and its safety switches
- Protection for the circuits in use
- Capacity for the appliances you plan to add

Adding a large appliance
Before adding an air-conditioner or other large load, ask whether the existing circuit can support it. A quote should explain any board or circuit changes and any time without power.
Safety switches and circuit breakers do different jobs
A circuit breaker protects a circuit against overload or short circuit. A safety switch detects current leaking from the circuit and is designed to reduce the risk of electric shock. A device may combine both functions. The appearance of a modern switchboard alone does not prove that every circuit has the required protection. Ask the electrician to identify what is fitted and test it.
When an upgrade may be needed
A damaged board, unsuitable protection, crowded equipment or a proposed new appliance can prompt an assessment. An upgrade decision depends on the existing installation and the work being added, not only the board’s age. The electrician should explain what needs repair, what needs replacement and what is an optional improvement. Do not remove the cover to inspect it yourself.
What to compare in a switchboard quote
Look for the circuits covered, devices supplied, testing, circuit labels and any changes to the enclosure. Ask whether the work requires supply to be disconnected, who arranges that and how long the expected interruption is. Request written details of completed work and any defects outside the agreed job. Keep access clear on the day.
