d) The prohibited TPS cable has been installed in electrical installations.
e) The TPS cable may have been imported and/or may have been installed by Lyon Electrical or others.
4. Reasons for prohibition
The TPS cable described in this notice is an electrical fitting that is, or may be, electrically unsafe, in that there is significant risk that a person may suffer harm as a result of dangers arising from use of, or passage of electricity through, the fitting.
The TPS cable described in this notice is, or may be unsafe as the TPS cable failed testing conducted on the ageing of the cable undertaken in accordance with AS/NZS 3808:2000+A1:2001+A2:2004 Table 5, Tests A&B and Table 6. Tests A&B are referenced by AS/NZS 5000.2.
- This test means that with time the cables will become brittle and live conductors may become exposed.
- This poses the risk of electric shock and fire due to arcing.
The TPS cable is non-compliant in that:-
- The TPS cable does not comply with Regulation 83 of the Regulations as it does not meet the relevant standard AS/NZS 5000.2 as listed in Schedule 4 of the Regulations.
- The TPS cable does not comply with Regulation 59 of the Regulations as it does not meet the relevant standard AS/NZS 3000.
Dated at Wellington this 12th day of February 2018.
