The board most people ignore

Your switchboard is the single most important safety device in the house, and it is the thing people look at least. If yours still has ceramic or rewireable fuses, that design is decades behind modern protection.

Warning signs

No test buttons, frequent tripping, a warm or discoloured board, a burning smell, or no spare ways to add a circuit. Any of these is worth a professional look.

What a modern board gives you

An individual RCBO per circuit means a fault in one area no longer blacks out the whole house — and you get far better shock and fire protection.

What I look for in a Adelaide switchboard

A lot of homes around Adelaide were wired when a couple of circuits and a few ceramic fuses were considered plenty. Add a modern kitchen, reverse-cycle air conditioning, an induction cooktop and a car in the driveway, and that old board is working far harder than it was ever designed to. The board itself rarely fails dramatically — it just quietly stops protecting you the way it should.

When I assess a board I'm not just counting spare ways. I'm checking the condition of the main switch and neutral bar, looking for heat damage and loose terminations, confirming whether there's genuine RCD protection on every circuit (not just the power points), and checking the earthing and bonding is actually doing its job. That's the part a quick "looks fine" never catches.

Signs a switchboard upgrade is overdue

• Ceramic or rewireable fuses instead of circuit breakers
• No "TEST" buttons — meaning no real safety-switch protection
• Breakers that trip repeatedly or won't reset
• A warm board, discolouration, or a faint burning smell
• No spare ways left when you want to add a circuit
• Original board in a home that's had renovations or extensions

Done properly, a switchboard upgrade is one of the highest-value safety jobs you can do on a home — and once it's in, it's sorted for decades. I test every circuit and hand over the compliance paperwork so there's a record it was done right.

Frequently Asked Questions

How long does a switchboard upgrade take?

Most domestic boards in Adelaide are a same-day job. Larger homes, sub-boards or boards that need the meter relocated can run longer — I confirm on site before starting.

Will my power be off the whole time?

Power is off only while I transfer circuits. I plan the sequence to keep the outage as short and predictable as possible.

Do I get compliance paperwork?

Yes. Every board upgrade is fully tested and you get a Certificate of Compliance for the electrical work.

Do you cover Adelaide?

Yes — Adelaide and Adelaide's inner metro suburbs. Call 0468 008 822 and I'll confirm I can get to you and roughly when.
