Switchboard repairs & upgrades

Switchboard faults fixed properly

The switchboard is the safety heart of your home. If it's tripping, buzzing, scorched or still running ceramic fuses, get it looked at now — not after something goes wrong.

Signs of a faulty switchboard

Repeated tripping

Breakers or RCDs that trip regularly, or won't stay reset at all.

Burning or scorching

Hot smells, discoloured plastic or scorch marks around the board.

Buzzing or crackling

Audible noise from inside the board means loose or arcing connections.

Old ceramic fuses

Rewirable fuse wire boards are decades past their safe service life.

No RCD protection

Without RCDs your circuits have no modern shock protection.

No spare capacity

A full board blocks heat pumps, EV chargers and kitchen upgrades.

Old fuse boards vs RCD protection

An old ceramic fuse board only protects the wiring in your walls from overload. It does nothing to protect the people in the house.

  • Fuse wire: slow, easily replaced with the wrong gauge, no shock protection.
  • Circuit breakers: reliable overload protection, resettable, still no shock protection.
  • RCDs / RCBOs: cut power in milliseconds on earth leakage — the modern NZ safety standard.

The upgrade process

  1. 1. Inspection: we assess the board, mains and circuit layout.
  2. 2. Fixed quote: a written price with no unknowns attached.
  3. 3. Scheduled shutdown: we agree a time window that suits you.
  4. 4. Install: new enclosure, RCBOs, labelling and tidy termination.
  5. 5. Test & certify: full testing plus your Certificate of Compliance.

Pricing guidance

Small repairs — a failed breaker, a loose connection, a single RCBO replacement — are usually a straightforward fixed-price visit. Full switchboard upgrades are priced on circuit count, board size, mains condition and access. Every quote is fixed before work begins, and we'll always tell you honestly if a repair will do the job instead of an upgrade.

Switchboard FAQs

How do I know my switchboard needs upgrading?

Ceramic rewirable fuses, no RCDs, frequent tripping, a burning smell, buzzing, scorch marks or a board that's simply full with no space for new circuits all point to an upgrade.

What is an RCD and why does it matter?

A residual current device cuts power within milliseconds when it detects current leaking to earth — the difference between a shock and a fatal electrocution. Old fuse boards have no RCD protection at all.

How long does a switchboard upgrade take?

Most residential switchboard upgrades are completed in a single day, with power off for only part of that time. Larger or multi-phase boards may run into a second day.

What does a switchboard upgrade cost in Auckland?

Pricing depends on circuit count, board size and whether the mains need replacing. We inspect, then quote a fixed price before any work begins — no surprises on the invoice.
