    Switchboard Upgrades

    Switchboard Upgrades in Toowoomba

    Most boards get upgraded because the house has outgrown them. New air conditioning, a charger in the garage, and a board sized for a 1980s house. Glenn opens it up, works out what you're actually drawing, and tells you what it takes.

    A Board Sized for a Different House

    What's on the wall now

    A main switch around 63 to 80 amps, every way in the board used, and lights that dip when the air conditioner kicks in. It was right for the house when it went in. The house has changed since.

    What goes back on

    An enclosure sized off a real load calculation, breakers matched to the cable that's already in the walls, RCD protection across the final subcircuits, every circuit labelled, and spare ways left over so the next job is a small one.

    QLD Legislation
    AS/NZS 3000:2018 (Wiring Rules)

    RCDs Aren't Optional Any More

    The wiring rules say final subcircuits in a home have to be protected by an RCD. That covers lights and air conditioning, not just power points. So when a new board goes in, every circuit ends up behind a safety switch.

    Check My Compliance

    The Real Question Is Capacity

    Nearly every call starts the same way: someone's booked an EV charger or a ducted system, and the installer has said the board won't take it.

    A charger draws 32 amps and holds it there. That's not a kettle. It runs for hours, on top of everything else the house is already using.

    Spare ways aren't the same as spare capacity. There's room in the box for another breaker, sure. Whether the main switch and the cable from the street can carry it is a separate question.

    So Glenn does a load calculation against AS/NZS 3000 rather than eyeballing it. Sometimes the existing main cable is fine and it's just a bigger board. Sometimes the supply from the street has to come up too, which means Ergon gets involved.

    Fair Pricing

    What It Costs

    There's no price list, because no two boards are the same. The main cable, the circuit count, asbestos and access all move the number. Glenn looks at what's there and gives you a real figure before anything starts.

    Pricing Disclaimer: Prices are indicative. Every situation is different and pricing may vary.

    Our Simple Process

    What Happens From Call to Certificate

    1. Glenn takes a look

      He opens the board, counts the circuits, checks for asbestos and looks at the main cable coming in.

    2. You get a plan and a real number

      Board size, circuit layout, anything extra he's found, and how long the power will be off.

    3. Old board out

      Power isolated, the existing wiring photographed, then the old board disconnected and taken away.

    4. New board in

      Enclosure mounted, main switch, breakers and RCDs fitted, circuits reconnected and labelled.

    5. Tested, then handed over

      Insulation, earth and RCD trip times checked, Electrical Safety Certificate issued, and Glenn shows you how to test it monthly.

    The Challenge

    Original ceramic fuses, circuits dropping out regularly, no safety switch protection, and a main service cable too small for the ducted air conditioning the owner wanted.

    Our Solution

    Glenn put in an 18-pole Hager board with RCBO protection on every circuit, and coordinated with the energy provider to take the main service cable from 16mm² up to 25mm².

    The Outcome

    The ducted system went in without trouble, every circuit sits behind a safety switch, and there's capacity left for a charger later.

    It depends on the property, and anyone quoting a number over the phone is guessing. The main cable from the street, how many circuits you want, whether there's asbestos, and how hard the board is to get at all move it. Glenn looks at yours and gives you a real figure before he starts.
