Can I just add an RCD to my existing board instead of replacing it?

Sometimes — but if the board is at end of life, partial upgrades are often false economy. We assess whether retrofit RCDs make sense or whether full replacement is the right call.

Do you handle strata switchboards?

Yes. We coordinate with the strata committee, body corporate, building manager, and individual lot owners. Notice of Service Work, by-law compliance documentation, and access scheduling are all included.

How quickly can you respond?

Quote inspections are typically scheduled within 2–5 business days. Emergency switchboard work (fire damage, severe overheating, loss of supply) gets 30–90 minute 24/7 emergency response. Call 0433 462 902.

How it works

Mosman, Cremorne, and Neutral Bay harbour-side properties combine high property values with the typical Lower North Shore electrical patterns: large multi-circuit boards, extensive outdoor entertaining circuits, pool/spa/jacuzzi equipment, and the salt-air corrosion from harbour exposure.

North Shore homes are stacking EV chargers, ducted air, data and home automation onto switchboards that were sized decades ago. We upgrade the board with the spare capacity and dedicated circuits those loads demand, and we handle strata-tower boards around Chatswood too.

About Switchboard Upgrade Electrician Sydney

A switchboard upgrade is one of the most consequential pieces of electrical work most Sydney homeowners will ever pay for. Done well, it gives you another 25 years of safe, code-compliant electrical service, full RCD shock protection on every circuit, and the headroom to add modern loads — induction cooktops, ducted air conditioning, electric hot water, EV chargers — without rewiring the whole house. Done poorly or deferred too long, your switchboard becomes the single largest fire and electrocution risk in your home.

Sydney Electrical Service is a fully licensed Level 2 ASP electrical contractor specialising in residential and strata switchboard upgrades across every Sydney metropolitan suburb. We handle the consumer mains, point of attachment, and metering side of the upgrade in-house — work most general electricians have to subcontract or coordinate separately with Ausgrid. Call 0433 462 902 for a written fixed-price quote, or book a site inspection online.

Electrical work in Mosman

Mosman is one of Sydney's older harbourside suburbs, and its housing reflects that. You'll find grand Federation and late-Victorian homes, plenty of interwar and Art Deco walk-up flats around the village and Military Road, and substantial harbourfront residences down toward Balmoral and the foreshore. A lot of these properties sit within heritage conservation areas, so meter boxes and switchboards often need to stay discreet and the original fabric left intact. In practice that means we regularly come across ageing rubber or VIR wiring well past its life, two-wire setups with no earth, and undersized fuse boards that need rewiring and proper safety switches to meet current standards.

Being right on the harbour, salt air takes its toll on outdoor switchboards, metering enclosures and consumer mains, so corrosion checks matter here. As an Ausgrid-accredited Level 2 ASP, we handle the network-side work too: overhead and underground service connections, point-of-attachment and consumer mains upgrades, metering, and three-phase supply for larger renovated homes. We also sort strata switchboards across Mosman's many flats and unit blocks.

Frequently Asked Questions

How long does a switchboard upgrade take?

A standard residential upgrade is usually completed in one day, with a 2–4 hour power-off window. Complex multi-circuit, strata, or boards requiring consumer-mains replacement can take two days.

Will I be without power for long?

Typically 2–4 hours during the actual changeover. If overnight isolation is needed, we coordinate so you have power restored by evening.

Do I need to replace my fuse board?

If it has ceramic fuses, no RCD protection, or is showing signs of overheating — yes. AS/NZS 3000:2018 requires RCD protection on all final subcircuits in new and significantly altered installations.

Will my insurance cover the upgrade?

Insurance generally does not cover voluntary upgrades. It can cover repair or replacement following damage (storm, surge, fire) — we provide insurance-grade documentation for these cases.

Does a switchboard upgrade increase my home's value?

Yes — particularly for properties going to market in older Sydney suburbs. Modern compliant switchboards remove a common pre-purchase inspection issue and signal recent electrical maintenance.
