Service Overview
Why Your Switchboard Matters on the Central Coast
The switchboard is the single most important piece of electrical equipment in any property. It is where the incoming supply is distributed, where a fault should be cut off, and where a safety switch either protects the occupants or fails to. Most older boards still installed across the Central Coast were designed for a simpler era of household electrical load — no air conditioning, no induction cooktops, no home offices, no EV chargers.
When a switchboard is outdated, overloaded, or missing modern safety switches, every electrical fault in the property becomes more dangerous. A modern board with RCDs and properly rated circuit breakers cuts power within milliseconds of a fault, turning what could have been a fire or electric shock into a nuisance trip.
NSW regulations now require RCD protection on most residential circuits, and insurers increasingly look at switchboard condition when assessing claims. Upgrading an old board is a safety, compliance, insurance, and capacity decision rolled into one.
Common Issues
Common Switchboard Problems We Fix on the Central Coast
Most switchboard callouts on the Central Coast start with one of the same handful of symptoms. Here is what tends to show up — and what should be treated as urgent rather than left until next week.

“Power went out across half the house during a storm. AB Electrical came out the same evening, found the fault in the switchboard, and had everything back on within two hours. Good communication throughout and fair pricing for after-hours work.”

“Smelled burning near a powerpoint and called AB straight away. They talked me through turning off the circuit over the phone and were at the house within 40 minutes. Turned out to be a loose connection arcing behind the wall plate. Fixed properly and checked the rest of the circuit too.”

“Called at 10pm on a Sunday after the safety switch kept tripping. AB Electrical was on-site fast, diagnosed a faulty appliance on the circuit, and made sure everything was safe before leaving. Professional and no fuss.”

Our Scope
Switchboard Upgrades & Repairs Across the Central Coast
AB Electrical handles the full scope of switchboard work on the Central Coast, from small additions like fitting safety switches to an existing board, right through to full replacement of ageing fuse boxes with modern enclosures. Every job is planned around the property, the existing wiring, and the way the household actually uses power.
Typical work also connects cleanly to broader upgrades — new circuits for air conditioning, induction cooktops, or EV chargers — so the switchboard is sized for how the property is actually used today, not how it was wired in the 1980s.

What affects the final price
- Age and condition of the existing board (ceramic fuses, wooden backing, asbestos panels all add scope)
- Number of circuits and whether new circuits are being added at the same time
- Whether consumer mains or meter work is also required (Level 2)
- Board location and accessibility
- Whether temporary supply is needed during the work
All figures are indicative. Every job is quoted before work starts.
What To Expect
What a Typical Switchboard Job Looks Like
A typical switchboard upgrade starts with a visit to photograph the existing board and confirm the scope — number of circuits, existing protection, any Level 2 involvement, and the customer's priorities. A written quote follows, then the work is scheduled for a day when the property can briefly be without power.
Most residential upgrades are completed in a single day with a short isolation window. Every circuit is re-terminated and labelled, every RCD and breaker is tested, and the customer gets a photo of the finished board before AB Electrical leaves the site.

FAQs
Questions about switchboards
The most common signs are ceramic fuses still in use, no safety switches (RCDs) on all circuits, repeated tripping under normal household load, a board that is full with no room for new circuits, visible damage or rust inside the enclosure, or advice from an electrician during other work. Any of these is worth a site inspection to confirm whether a full upgrade, a partial refresh, or an RCD retrofit is the right approach.
Ceramic fuses provide no overload protection beyond the fuse wire itself, they have no RCD (safety switch) protection against earth leakage faults, and they are not compatible with modern circuits or higher-load appliances. They were standard in the 1960s-1980s but do not meet current NSW wiring rules and are a red flag for insurers assessing claims.
For a typical full switchboard replacement, the supply is isolated for 4 to 6 hours. The isolation window is planned in advance and confirmed with you before the work is scheduled so there are no surprises on the day. Most residential switchboard upgrades are completed in a single day.
Sometimes yes — especially on older properties where the consumer mains (the cable from the street to the meter) are undersized for the modern load. AB Electrical holds ASP Level 2 accreditation and can do both the switchboard upgrade and the consumer mains upgrade in one coordinated job, saving a second isolation window and a second round of paperwork.
Sometimes. If the existing board is a modern enclosure in good condition, an RCD retrofit ($400-$900) may be sufficient. If the board is ceramic fuses, wooden-backed, or full with no spare ways, a full replacement is usually the better approach. A site inspection confirms which option applies.
NSW requires RCD protection on power and lighting circuits in rental properties. A switchboard upgrade is often the most practical way to achieve this — adding individual RCDs to an old board is sometimes possible but can be more expensive than a clean replacement when the board is already outdated.
Yes. A Certificate of Compliance for Electrical Work (CCEW) is issued for the relevant work and lodged in line with NSW requirements. The finished board is fully labelled with a circuit schedule, and a photograph of the completed work is supplied for the property owner's records.
Sometimes. Adding RCDs to an existing modern board first ($400-$900) and planning a full replacement later is a viable approach if the existing board is in reasonable condition and has room. AB Electrical can advise on staging during the site inspection and provide a written scope for each stage.
