In commercial installations, the new AS/NZS 3000 wiring rules require additional RCD protection.
- 30mA RCDs shall be installed on all final sub-circuits supplying lighting and socket outlets ≤ 32A. (previously 20A)
- 30mA RCDs should be installed on all final sub-circuits supplying 32A fixed wired equipment.
- 30mA RCDs shall be installed on all final sub-circuits supplying 32A fixed wired equipment that may represent an increased risk of electric shock such as environmental conditions (e.g. wet areas) and the type of electrical installation and process being conducted.
