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

From Mosman and Neutral Bay through Lane Cove and out to Wahroonga and Hornsby, North Shore electrical systems share a common challenge: the largest residential properties in metropolitan Sydney supplied by overhead consumer mains running through some of its densest tree canopy.

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 Wahroonga

Wahroonga is classic Upper North Shore: large heritage homes on generous, leafy blocks, with grand Federation and Arts-and-Crafts houses sitting alongside substantial interwar and mid-century residences. These are big homes with big electrical demands, ducted air conditioning, pools, multiple living zones and outbuildings, and the original wiring and switchboards simply weren't built for it. We frequently upgrade undersized boards, fit proper RCD protection and rewire circuits where decades-old cabling has been pushed well past its design.

For homes of this size, three-phase supply is often the right answer, and as Level 2 electricians accredited with your Ausgrid network we can carry out that upgrade end to end, including consumer mains and the point-of-attachment connection. The heavy tree cover that gives Wahroonga its charm also means overhead service lines take a beating in storms, so private pole repairs and service-line work are a regular part of keeping these established properties safely powered.

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.
