ELECTRICITY (WIRING) REGULATIONS - REGULATION 21

Procedures for inspection, testing and certification

(1) Tests on a fixed electrical installation shall be carried out with proper
tools and testing equipment and in accordance with accepted practices so that
no danger to persons or property can occur even if the circuit being tested is
defective.

(2) Results of tests and inspections shall be recorded, dated and certified by
the registered electrical worker who carried out the tests and inspections.

(3) Where a fixed electrical installation is divided into more than one part,
the individual parts need not be inspected, tested and certified by the same
registered electrical worker, and a single certificate in a form specified by
the Director may be issued and certified by a registered electrical worker to
cover a number or all of the individual parts, as long as he has received the
appropriate certificates certified by other registered electrical workers for
the individual parts, and is satisfied that the certificates are completed and
signed by a registered electrical worker of appropriate grade.

(4) A registered electrical worker shall ensure that the tests and inspections
covered in his certificate have been carried out within a reasonable time,
normally not exceeding one month, before the date of certification and that
the results of the tests and inspections are satisfactory. (Enacted 1990)
