Switchboard Upgrades & Safety Switches around Shellharbour
Shellharbour has a lot of established homes, many with original wiring and switchboards. That makes a safety check worthwhile before a renovation, and it's often why circuits trip or power points run hot.
Switchboard upgrades are one of the most common jobs in older homes. Replacing ceramic fuses with circuit breakers and safety switches on every circuit is a real safety improvement.
Salt air near the beach corrodes standard outdoor fittings and switchgear, so outside work in Shellharbour uses fittings rated for coastal conditions.

Why safety switches matter
A safety switch cuts power in a fraction of a second if current leaks to earth, for example through a person. Older homes often have none, or only one protecting the power points. We'll check what you have and recommend what's needed.
