500+ switchboard upgrades
Experience assessing existing boards, circuit protection and the work needed for a repair or replacement.
Electrical Services
Switchboard repairs, safety-switch installations and partial or complete upgrades for homes and businesses. We assess the board’s condition, circuit protection and proposed loads before recommending what needs changing.

A switchboard upgrade is not always a full replacement. A suitable board may allow a targeted repair or additional safety switches; a damaged, full or unsuitable enclosure may need more extensive work.

AB Electrical assesses the existing board and wiring alongside any renovation or new equipment. We distinguish changes to circuit protection from changes to the property’s supply capacity, including any separate consumer-mains or Level 2 work.
Circuit breakers and fuses respond to excessive current. Safety switches (RCDs) detect earth leakage; an RCBO combines these functions. None makes faulty equipment safe to touch.
Keep away from a hot, damaged, sparking or crackling board. Do not touch devices to check their temperature or repeatedly reset a tripping circuit. For smoke, fire or immediate danger, leave and call 000.
You deal with the same electrician throughout your electrical work. If a fault is caused by our installation or repair workmanship, we put it right at no extra charge.
Experience assessing existing boards, circuit protection and the work needed for a repair or replacement.
The same electrician assesses and completes your electrical work, so you have direct contact about the finished board.
Where the job involves new loads, we check whether separate consumer-mains, connection or metering work is needed.
The finished work is tested and labelled, with applicable electrical compliance records and a photograph supplied.

Most residential upgrades are completed in one day. The expected power-off window depends on the work; tell us about medical equipment, refrigeration or access systems that rely on electricity before scheduling.
Assess the board, circuits and wiring, and identify any separate supply or meter work.
Provide a written quote for planned work and confirm the expected isolation arrangements.
Isolate as required, complete the agreed work and test the affected installation.
Explain the finished board, provide its circuit labels and photograph, and supply the relevant electrical compliance records.
These indicative ranges are for early budgeting, not an AB Electrical price schedule or a quote for your property. The assessment determines the work, inclusions and actual price. Planned work is quoted in writing; urgent work is discussed separately.
| Job | Typical range |
|---|---|
| Add safety switches to an existing modern board | $400 – $900 |
| Partial switchboard upgrade (refresh + RCDs) | $900 – $1,800 |
| Full switchboard replacement (standard home) | $1,800 – $3,500 |
| Full switchboard replacement (large home or complex) | $3,500 – $6,500 |
| Switchboard repair (single breaker or RCD) | $280 – $650 |
All figures are indicative. Planned work is quoted in writing before it starts. For urgent work, call to discuss the fault and likely costs.

Understand the signs that a switchboard may be outdated, overloaded, or no longer suited to the way the property is used.
