Can’t I use Connectors and Tape or a Joint Box?
NO! BIG FINES!!
Tape, connectors, connectors with tape, and even junction boxes hanging freely or pushed in the wall boxes fall short of AS/NZS 3000:2018 c: 1.5.4.” A proper enclosure must be used, rated to IP4x and secured in place.”
Unenclosed junctions (connectors) hanging out of the wall are a defect under 1.5.4.4(a) and 1.5.4.4(b). Junction box’s hanging out of the wall on the ends of cables; section (b) covers off on why you can’t have this specifically, and the term used is “shall be firmly secured in place”.
The Purple Box was created in consultation with inspectors and compliance regulators to eliminate this problem and keep contractors from taking unknown and unnecessary risks.
Fines can and have been issued to contractors for not carry out safe work as the above due to falling short of the above requirements!!
