Electrical compliance and certificates

Electrical codes and regulations exist to ensure that electrical systems are designed, installed, and maintained to minimize the risk of electrical fires, shocks, and other hazards. 

Registered electricians are trained to follow the codes and regulations that ensure your home or building is compliant and safe. Your electrician arranges the necessary compliance certificates once your electrical job is completed.

Under New Zealand regulations electricians issue a Certificate of Compliance (CoC) to certify electrical installations. This guarantees the work has been completed by a licensed electrician who’s registered with the Electrical Workers Registration Board (EWRB), meets NZ safety standards and codes, and has been tested.

Routine maintenance work, such as replacing sockets and light fittings or repairing appliances, requires an Electrical Safety Certificate (ESC). (All CoCs also need an ESC accompanying them).

What does a COC cover?

  • Wiring methods: how wires are routed, protected, and grounded to minimize the risk of short circuits and electrical fires.
  • Circuit capacity: Regulations specify the maximum current that wiring, and circuit breakers can handle, preventing circuit overload.
  • Outlet placement: Codes outline safe locations of where outlets should be in residential and commercial spaces.
  • Ground and arc fault protection: Ground Fault Circuit Interrupters (GFCIs) and Arc Fault Circuit Interrupters (AFCIs) are required in specific locations to prevent electrical shocks and fires.
  • Electrical panels: installation, maintenance and ensuring panels are safely accessible and adequately sized.

Why are electrical codes and regulations necessary?

  • Safety: electrical codes are there to protect human lives and property. Faulty electrical systems can lead to fires, electrocution, and other life-threatening incidents.

Consistency: they provide a standardized framework for electrical work, ensuring that electrical systems are reliable and uniform, regardless of who installs them.

  • Prevention: Codes aim to prevent accidents – by adhering to required standards we reduce the likelihood of electrical mishaps.
  • Legal Compliance: Non-compliance is not only unsafe but can lead to legal issues with property transactions.
