Appendix CPeriodic verification#

Requirements for electrical installations#

Comply with the requirements as set out in AS/NZS 3019.2007 Electrical Installations – Periodic Verification and as follows.

Clause 1.1 Where other traffic related equipment (for example CCTV or communications equipment) has been connected to the signals installation, the relevant periodic verification clauses apply.

Clause 2.1 Immediate electrical risks (exposed live conductors, unearthed equipment and incorrect polarity) must be rectified when discovered and the ESO notified.

Where other test results of an installation are found not to comply with the requirements of AS/NZS 3000:2007 Wiring Rules (for example high leakage current in a multicore cable) consideration must be given to the risk to road users of having signals switched off.

Where signals must be switched off for maintenance, police must be present to direct traffic.

Clause 2.8 For standard installations, the maximum interval between inspections is five years. Where harsh environmental conditions exist, more frequent inspections must be carried out. Once inspections have a documented history, frequencies may be adjusted to suit the specific installation requirements.

Clause 3.2 (c) – not required

Clause 3.2 (h) – not required

Clause 3.2 (j) – not required

Clause 3.2 (l) – not required

Add the following clauses to 3.2

Clause 3.2 (n) Covers/lids are not broken or missing

Clause 3.2 (o) Electricity entity side of the point of supply is not showing signs of deterioration.

Clause 3.2 (p) Electrical components have been replaced with identical units.

Clause 3.2 (q) Switchboards and poles/posts are adequately sealed against vermin.

Clause 4.3 (b) – not required

Clause 4.6 – not required

Clause 4.7 (b) – not required

Clause 4.7.1 (b) For each pole/post, this is verified by carrying out earth fault loop impedance tests at each pole/post between the A2 connection and the pole/post.

Clause 4.7.4 – Leakage current testing is required on the consumers mains and the multicore cable.

Clause 5.2 (a) – not required

Clause 5.3 (b) – not required

Clause 5.4 – not required

Clause 5.5 – Earth fault loop impedance measurements are required at the switchboard for external impedance and at the end of each multicore run for total circuit impedance.

Clause 5.7 – not required

Clause 5.9 – not required
