Split System Air Conditioning Installation in Werribee — What to Expect
Planning a split system install in Werribee? Here's how the electrical side works — dedicated circuit, isolator, switchboard check and CES.

Summer in Werribee is no joke. A split system is the most efficient way to keep a room or whole home comfortable — but the electrical side matters as much as the refrigeration.
What the electrician does
- Checks your switchboard has capacity and an RCBO available.
- Runs a dedicated circuit back to the board (sized to the unit — usually 16A for residential).
- Installs a weatherproof isolator within sight of the outdoor unit, as required.
- Connects, tests and issues a Certificate of Electrical Safety (CES).
What to look out for
- Quotes that don't mention a dedicated circuit are usually piggybacking off an existing one — that's not compliant for most units.
- An installer without electrical credentials can mount the unit but legally can't connect it.
- Outdoor unit placement affects cable run length and noise — get it right the first time.
