to a Cable of V75 Thermal Rating
Pursuant to Regulation 102 of the Electricity Regulations 1997, and acting under delegated authority from the Chief Executive of the Ministry of Economic Development, pursuant to section 41 of the State Sector Act 1988,
I, Graham Boxall, Manager, Operations, Ministry of Consumer Affairs, hereby notify that the following electrical fitting, being a TPS cable as described below, is prohibited from importation, sale, installation or use when its electrical overload protection exceeds the rating applicable to a cable of V75 thermal rating.
This prohibition is to take effect on and from the date following the date of publication of this notice in the
New Zealand Gazette.
Description
The TPS cable is a flat profile, white sheathed, "Twin and Earth", building wiring cable of construction similar to that specified in AS/NZS 5000 and having the earth conductor located in the centre position between the phase and neutral conductors. It was supplied with 1.0, 1.5, 2.5 and 4.0 square millimetre conductors.
The TPS cable is "recognisable" by a complete lack of marking on its sheath and was/is supplied on drums marked:
Manufacturer: "BANCO" - Taiwan
Insulation: PVC V90
Sheath: PVC V90
Voltage: 450/750V
This cable was supplied in New Zealand by PoweRun
New Zealand Limited (also known as Sheweta Enterprises (NZ) Limited.
Details of Hazard
The cable constitutes or may constitute an electrical hazard in that:
? when tested for its ageing properties at its marked capacity of V90 rating, the cable becomes brittle indicating that the cable will increasingly function unsafely in normal use, with consequential danger to property from fire, over its lifetime when used at a rating above that applicable to a V75 rated cable.
Reasons for Prohibition
The "BANCO" TPS cable does not comply with the safety requirements of Electricity Regulation 69, in that:
? the cable, being a fitting, will function unsafely in normal use, so as to cause danger to property from fire.
Accordingly, I issue this prohibition.
Signed this 4th day of February 2005.
GRAHAM BOXALL, Manager, Operations, Ministry of Consumer Affairs.
