Your Local Underground Power, Shed & Outdoor Electrician

Under Australian Standards (AS/NZS 3000), underground electrical cabling must be buried at a minimum depth of 500mm inside heavy-duty orange electrical conduit, with marker tape laid above it to prevent future damage.

Yes, overhead aerial lines can be used if trenching is impossible. They require heavy-duty catenary wire and specific height clearances (minimum 3.5m over paths, 4.9m over driveways) to prevent vehicle contact.

Spas usually draw significant power (typically 15 Amps to 32 Amps or more) and require a dedicated circuit run from the main switchboard, protected by an RCD and a local IP66-rated rotary isolation switch.

I will assess your main switchboard capacity. If the main board is overloaded, a mains capacity upgrade or switchboard upgrade may be required before running sub-mains to a shed.

It is a smaller switchboard installed inside a detached structure (like a shed). It houses its own circuit breakers and safety switches, allowing you to isolate and reset shed circuits locally.
