I watch a few UK sparkies ... edition 18 states that a plastic DB must be replaced with a metal DB ... wow.

I havent installed a metal DB since the 1900s ... maybe we should get them to ship container loads of all their plastic DBs to SA ... mind you at R450 for a complete wired plastic DB ... you not gonna get cheaper than that ... never say never ... i found what use to be a good quality brand of electrical PVC components ... i nearly crapped myself when i saw how they have reduced the standard to compete with chinas junk ... i had to use a remeamer to clean the inside of the box and sand the outside to get the cover to secure on an an elbow.

My step bit works way better on plastic enclosures

Lets hope the SANS dont hear about this dangerous environment plastic enclosures create ... we have the DOL ... it would mean they would have to roll out from under their shell and start checking ... so we are in the clear.
