In last month’s update, we advised that we were investigating the compliance of building wiring cable from a number of suppliers. The investigation is now primarily focussed on cable imported by one company and used by that company at a number of construction projects.
We have evidence that there was one shipment imported in July 2016 and the possibility of two later shipments.
We have no evidence that this cable has been distributed by any other companies in New Zealand.
The cable under investigation is a range of two- and three-core thermoplastic-sheathed cable with markings that include ‘CERTIFICATE No. EESS 150102-0’.
Results of testing samples of this cable indicate it is not compliant with the relevant standard: AS/NZS 5000.2 Electric cables - Polymeric insulated – Part 2: For working voltages up to and including 450/750 V.
While not necessarily unsafe at present, the cable has failed its ageing test and may become unsafe over time. This cable must not be used and if any of this cable is found it will need to be removed.
We are also investigating the validity of documentation attesting to the compliance of this cable.
We are looking at other cables in the market and auditing the documentation of all cable which we are aware is present in the market. This auditing and follow up action will continue as necessary for some weeks ahead.
We ask that installers remain vigilant about the cable they install. Our August update includes guidance on how to identify whether the cable is likely to be compliant.
