Emergency Response in Earlwood
Licensed electrician dispatched fast · 24/7 · 30–60 min
Strathfield, Burwood, and Concord post-war brick veneers face their own electrical challenges — three-phase legacy supply, oversized backyards with detached structures (granny flats, sheds, studios), and original aluminium wiring developing oxide-related hotspots.
- A tingle when touching outdoor taps, metal balustrades, pool ladder, or BBQ
- A buzzing or humming sound from any outdoor power point or garden light
- Visible scorching or discolouration around an outdoor outlet
- Water visibly entering a switchboard, particularly external boards on the side wall
- Pool/spa equipment that hums but does not start, or starts then trips
- A "smell of weather" mixed with electrical smell on the affected circuit
About Why Does My RCD Trip When It Rains?
An RCD that trips only during or after rain has moisture reaching a live conductor — typically through a cracked weatherproof power point, a failing garden-light fitting, or waterlogged pool equipment. That is a real earth fault, not a nuisance — the circuit is unsafe to use until the leak is fixed, so book a diagnostic online or call 0433 462 902 now.
It is one of the most common storm-season callouts we get across Sydney, peaking between November and March when east-coast lows and afternoon thunderstorms push horizontal rain into fittings never designed to handle weather from that angle. Sydney Electrical Service attends 24/7 across every Sydney postcode, so the fault can be found and the circuit restored before the next downpour.
What to Do Right Now in Earlwood
- If rain is still falling, do not touch outdoor electrical equipment.
- Open the switchboard. Identify the tripped RCD.
- Turn off every breaker downstream of that RCD. Reset the RCD to ON.
- Bring breakers back on one at a time. The breaker that re-trips the RCD is the wet circuit.
- Leave that breaker OFF. Unplug everything on the circuit (outdoor power points, garden lights, pump equipment).
- Wait until the rain has stopped and the equipment has dried. Often the circuit will reset successfully on a dry day — but the fault has not gone away.
- Do not "tape over" the problem with silicone or waterproof bags. It is a temporary illusion of safety.
- Book a Level 2 electrician to find and repair the leak before the next storm.

Renovation-era cable damage is a consistent issue in Inner West homes — the high-density extension and reno history through Newtown, Glebe, and Balmain has accumulated decades of pinched, drilled, or damaged cable that surfaces years later.
