FAQs
Why would I need an electrical panel upgrade in Mascot?
Older switchboards often struggle to handle today’s higher household loads—air-conditioning, EV chargers, induction cook-tops, and home offices. An upgrade improves safety by replacing porcelain fuses with modern circuit-breakers and RCDs, reduces nuisance tripping, meets current AS/NZS 3000 wiring rules, and provides spare capacity for future circuits.
How can I tell my current switchboard is outdated or unsafe?
Warning signs include ceramic re-wirable fuses, no residual-current devices (safety switches), frequent breaker trips, flickering lights, burning smells, buzzing sounds, or visible scorch marks. If your home in Mascot was built before the early 1990s and hasn’t had a switchboard replacement, it’s likely non-compliant with current standards.
What does the upgrade process involve?
A licensed Level 2 electrician first inspects the existing service, calculates load, and lodges an Ausgrid CES (Certificate of Electrical Safety). On the scheduled day power is isolated, the old panel is removed, new metal-clad enclosure, main switch, circuit-breakers, RCDs/RCBOs, and surge protection are installed, earthing and MEN are tested, and labeling is completed. Finally, supply is restored and a compliance certificate is issued.
How long does a typical panel upgrade take and will I lose power?
Most residential switchboards in Mascot can be upgraded in 4-6 hours. You will be without power for that period, so we recommend charging devices, planning meals, and switching off sensitive electronics beforehand. Larger homes or meter relocations can extend the outage to a full day.
What permits or inspections are required in Mascot?
All switchboard upgrades must be carried out by a licensed NSW electrician. A Certificate of Compliance for Electrical Work (CCEW) is lodged with NSW Fair Trading, and Ausgrid may inspect works randomly. If the main service fuse, consumer mains, or point of attachment is altered, a Level 2 ASP is mandatory and a Network Application must be approved before work starts.
How much does an electrical panel upgrade cost in Mascot?
Prices vary with panel size, number of circuits, need for meter relocation, and whether the consumer mains also need replacing. For a typical three-bedroom home expect $1,400–$2,200 inc. GST. Upgrading to 3-phase supply, adding surge protection, or installing an EV charger provision can push costs to $3,500+. We provide fixed quotes after a free on-site assessment.
