1. Outdoor lighting fixtures
Insultation can melt in poorly installed outdoor electrical fittings, leading to a short circuit. You might then have to change your entire distribution board.
2. Circuit breakers for outdoor sockets
Because of the risk of exposure to water, outdoor sockets should have a circuit breaker. Without this you are risking electric shocks and fire.
3. Bathrooms and kitchens
Sockets, light switches and other electric installations in wet environments can be risky. If you are planning a bathroom or kitchen renovation, make sure a qualified electrician inspects the wiring.
