SUBMAIN INSTALLATION ELECTRICIAN GOLD COAST

A submain is a dedicated cable run from your main switchboard to a secondary switchboard, giving a granny flat, shed, workshop or subdivided section of your property its own separate power supply. Bonus Electrical installs new submains and upgrades existing ones, sizing the cable correctly for the load it needs to carry and fitting a compliant secondary switchboard at the other end. This is common when adding a granny flat, converting a shed into a workshop or studio, or subdividing a block, since each additional structure or dwelling generally needs its own metering and protection rather than sharing an overloaded circuit. We calculate the total load before starting so the submain is sized correctly the first time, rather than needing costly upgrades later as more circuits are added. Every installation is tested and certified to Australian Standards, giving you documented proof of compliance for council or building approval. Call Bonus Electrical today for a free quote.
