By interstate agreement and legislation, an electrical safety certificate issued by the appropriate regulatory authority in any State or Territory is recognised by all other States or Territories.
Articles approved by a regulatory authority must be identified with a valid Electrical Safety Certificate Number issued by a State or Territory authority. An electrical safety certificate number typically consists of a letter to indicate the State of approval, followed by a number.
