Technical FAQs 3

Can a winding generator be used as an isolated inverter?

Isolated winding generators and isolated inverters must only be used to supply a separated circuit for electrical equipment installed in accordance with AS/NZS 3000 Wiring rules, and each winding must supply not more than one item of Class I (earthed conductive parts) electrical equipment.

Where should sub-circuits of construction wiring be protected?

All final sub-circuits of construction wiring must be protected at the switchboard where the sub-circuits originate by a residual current device (RCD), with a maximum rated residual current of 30mA, that operates in all live (active and neutral) conductors.

What is construction wiring?

Construction wiring (Construction and demolition wiring) means wiring systems installed to provide electrical supply for construction and demolition work, and is not intended to form part of the permanent electrical installation. The term includes:
