A main switch that trips for no obvious reason. A board that hums, smells hot or has a scorch mark around one breaker. A ceramic fuse that keeps blowing. These are repair calls, and plenty of them can be fixed without replacing the whole board.
Blue Link Electrical finds what is wrong with your existing switchboard, repairs it when a repair is the right answer, and tells you plainly when it isn't.
A switchboard repair fixes a specific fault in the board you already have. That might be a single breaker that has failed, a loose or overheated connection, a safety switch that no longer trips when it should, a damaged neutral or earth link, a cracked cover, or a meter box door that lets rain in. The enclosure, most of the devices and the circuits stay as they are; only the parts that have failed are replaced or remade.
Repairs make sense when the rest of the board is in reasonable condition and the fault is isolated. They make less sense when the board itself is the problem: ceramic fuses throughout, no safety switch protection, no room for new circuits, or damage suggesting the whole board has been running hot.
A safety switch that trips with nothing plugged in, or a main switch that drops out under normal load, can be a failing device or a fault further down the circuit. We test both before replacing anything.
Usually a loose connection arcing or a breaker on its way out. Keep clear and don't remove the cover. Our buzzing switchboard guide explains why it matters.
Brown or black marks around a breaker, a melted terminal or a board that is warm to the touch point to overheating at a connection. Damaged devices and cable ends are replaced and the connections remade.
A rewireable fuse that keeps blowing is telling you something about the circuit, and the fuse wire fitted is not always the right rating. See ceramic fuse switchboard replacement.
Rusted hinges, perished seals or a damaged door can let rain reach the board. We deal with the entry point and test the board and circuits for damage.
Missing blanks or covers can leave live parts exposed, and unlabelled circuits turn isolation into guesswork. Covers are replaced and circuits labelled as part of the repair.
You get a straight recommendation, not an automatic upsell. The questions are simple. Is the fault confined to one part of the board? Do the remaining devices and connections test sound? Does the board already have safety switch protection on its circuits? Is there room for what you plan to add, such as air conditioning, an induction cooktop or an EV charger?
One failed breaker or safety switch, a single overheated connection, a damaged cover or a leaking meter box door, on a board that otherwise tests well and already has RCD protection.
Ceramic fuses throughout, no RCD protection, heat damage in several places, an old backing panel, or no space for the circuits you need. Repairing one fault would leave the rest of the risk in place.
When an upgrade is the better answer, we explain why and quote a switchboard upgrade alongside the repair so you can compare the two. If you want to check your own board first, the signs you need a switchboard upgrade guide is a useful checklist.
What happened, when it started and what tripped or failed.
With power isolated where needed, we look for heat, damage and loose connections.
Insulation resistance, continuity and RCD testing to confirm the cause.
The repair, and any alternative, set out in writing before we start.
Failed devices replaced and connections remade.
Affected circuits tested and confirmed safe before power is restored.
If the board is hot, smoking, sparking or smells of burning, switch off at the main switch only if you can do it safely without touching anything wet or damaged, keep everyone clear and call. If there is fire, call 000 first. Our 24/7 emergency electrician line handles these calls; after hours, we attend emergencies only.
For everything else, including a breaker that trips now and then or a board you simply don't trust, book a standard visit. If the fault turns out to be in a circuit or an appliance rather than the board, our electrical repairs service covers that as well.
Switchboard repairs in NSW must be carried out by a licensed electrician and comply with AS/NZS 3000. Where a repair is notifiable electrical work, you receive a Certificate of Compliance for Electrical Work (CCEW). Blue Link Electrical holds NSW Electrical Contractor Licence 332956C.
As well as homes, we repair commercial switchboards in shops, offices, restaurants, cafes and warehouses, including three-phase boards. For a business, we plan any shutdown around trading where we can. If a commercial board needs replacing rather than repairing, see commercial switchboard upgrades.
Often, yes. If the fault is confined to one part of the board and the rest tests sound, replacing the failed device or remaking a connection is usually enough. If the board has ceramic fuses throughout or no safety switch protection, we will recommend an upgrade and explain why.
Buzzing usually comes from a loose connection arcing or a breaker that is failing. Keep clear, don't remove the cover, and call a licensed electrician.
A blown or damaged fuse can be dealt with, but ceramic fuses give no protection against electric shock. In most cases we recommend replacing the board with circuit breakers and safety switches.
