  Yes

  No

  N/A

National Construction Code Requirements

• As stipulated in AS/NZS 2067 Section 5.5, electrical switchrooms shall comply with the requirements of the Building Council of Australia's National Construction Code (NCC). BCA Class 8 buildings are used as a guide.

• Do all egress paths around the switchboard have sufficient battery-backed exit lighting?

  Yes

  No

  N/A

• Is there sufficient emergency lighting in the switchboard cupboard (where applicable)?

  Yes

  No

  N/A

• Is the external area to the switchboard free from blockages (i.e. vehicles, gardens, etc) within 1 metre, either existing or potential?

  Yes

  No

  N/A

AS/NZS 3000 Requirements

• As per AS/NZS 3000, there are minimum safety requirements in a switchroom to ensure a safe area is maintained for both electrical operation & electrical workers.

Safety

• Is there minimum 600mm clearance between the all electrical (open) panels and other obstructions (such as other panels, walls, fences, pits)?

  Yes

  No

  N/A

• Do all panels require a tool to gain access to live parts?

  Yes

  No

  N/A

• Are all switchboard doors & panels secure and in good condition?

  Yes

  No

  N/A

• Is there a secondary egress path for boards with capacity over 800A, length >3m or fault current of >15kA?

  Yes

  No

  N/A

• Is the board in a location where smoke or fire could impact egress from a building?

  Yes

  No

  N/A

• Are the seals around the switchboard suitable to contain smoke and fire in the event of a failure (minimum IP5X)?

  Yes

  No

  N/A

• Are there any exposed or easily accessible live parts?

  Yes

  No

  N/A

• Switchboard is not in a hazardous area?

  Yes

  No

  N/A

  Yes

  No

  N/A

• Are safety services (lifts, fire, etc) separated from general power distribution?

  Yes

  No

  N/A

• As per section 7.2, it is critical that safety services are not at risk of isolation due to fault in another part of the electrical system.

  Yes

  No

  N/A

• Is there suitable segregation between circuits in cable tray/conduit?

  Yes

  No

  N/A

• Are cable trays secure, no rust/degradation and earthed at all non-bolted joints?

  Yes

  No

  N/A

• Are all circuits labelled correctly?

  Yes

  No

  N/A

• Earths identified & correctly labelled?

  Yes

  No

  N/A

• Do circuits into Hazardous Areas comply with AS/NZS 60079?

  Yes

  No

  N/A

• All power circuit must be protected by 30mA protection, with appropriate glanding. Final circuit equipment must be suitably rated. If you are unsure, isolate the circuit and consult your supervisor.

Switchboard Area Lighting

• Is lighting sufficient around the switchboard?

  Yes

  No

  N/A

• 160lux or greater is recommended for general electrical tasks.
  400lux or greater is recommended for electrical maintenance work, and can be achieved by task lighting.
