Tree-heavy suburbs — Wahroonga, Killara, Pymble, Hunters Hill, Lane Cove — see the highest rate of overhead consumer mains damage in metro Sydney. East-coast lows and storm-driven branches account for hundreds of point-of-attachment and service-mains callouts every storm season.

⚠ Stop — Call Immediately if You Notice Any of These:

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 Lane Cove

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.

Common Questions

Why does my RCD only trip when it rains and not when it's dry?

The leakage path only exists when water is present. Cracked seals, perished cable jackets, or compromised gaskets remain electrically intact when dry, but water bridges the gap from active to earth and the RCD detects it instantly.

Can I just leave the outdoor circuit off until summer ends?

You can — but the underlying fault is not going to fix itself, and the next storm will trip the RCD again. Worse, water and electricity tend to make damage worse over time, not better.

My RCD trips after the rain stops, not during. Why?

Water inside an enclosure can take hours to fully bridge a gap, especially if it has dripped through ceiling material or seeped into a junction box. Some leaks only become severe enough to trip after the body of moisture has saturated the insulation.

Are outdoor power points always meant to be waterproof?

They must be IP-rated for their location and have a properly functioning weatherproof cover. AS/NZS 3000 specifies minimum IP ratings for outdoor installations. Once the cover is missing, cracked, or warped, the rating is gone.
