RCD Tripping Glenhaven
Emergency Response in Glenhaven
Licensed electrician dispatched fast · 24/7 · 30–60 min
From Castle Hill through Kellyville and out to Rouse Hill, Hills District electrical systems share a common challenge: large-block family homes with extensive modern appliance loads (multi-zone AC, electric vehicle chargers, induction cooktops, ducted vacuum) running on switchboards that mostly meet AS/NZS 3000:2018 baseline but are now reaching the limits of their planned capacity.
- A tingle, prickle, or buzz when you touch a tap, appliance, or shower fitting
- A burning, fishy, or "electrical" smell anywhere on the affected circuit
- Hot or discoloured power points on the affected circuit
- An RCD that holds for a few seconds then trips — strongly suggests a real, active leakage
- An RCD that won't trip when its TEST button is pressed — the device itself has failed
About Why Is My RCD Tripping?
RCD tripping is caused by earth leakage — most often a faulty appliance, moisture inside a fitting or cable, degraded wiring insulation, or cumulative leakage across shared circuits. If tripping repeats or returns after resetting, you have an active fault that can cause electrocution or fire; call 0433 462 902 or book a diagnostic before resetting again. Every trip must be treated as real: RCDs are the single most important shock-protection device in your switchboard.
Sydney Electrical Service handles RCD diagnostics 24/7 across every Sydney suburb — from older Federation cottages in Marrickville and Annandale to high-rise strata in Pyrmont and Zetland. Northern Beaches outdoor entertaining areas face accelerated insulation breakdown from salt air and weather, making them a frequent source of hard-to-trace earth leakage.
What to Do Right Now in Glenhaven
- Open the switchboard. Find the tripped RCD (the toggle will be in the middle position, or fully OFF).
- Switch every breaker downstream of that RCD to OFF.
- Reset the RCD to ON. It should now hold because no circuits are live.
- Switch breakers back on one at a time with a 30-second pause between each.
- The breaker that re-trips the RCD is the faulty circuit.
- Unplug everything on that circuit and try again.
- If the RCD holds, plug appliances back in one at a time to find the offender.
- If it doesn't hold with everything unplugged, the fault is in the fixed wiring or a hardwired appliance — leave it OFF and call us.
Electrical work in Glenhaven
Multi-zone AC additions to homes that originally had single-AC capacity are a recurring switchboard-load issue — frequently requiring per-circuit RCBO retrofits or main-switch upsizing.

My RCD trips when I switch on the dishwasher (or kettle, dryer, washing machine). Is the appliance dead?
