Electric safety certificate/CCU/fuse boardMake Text Bigger
Hello, I have a number of properties where the fuse board/CCU is not in a metal cabinet or metal frame. In fact on some certified electricians have over the years replaced the old board with plastic boards to include circuit breakers etc.
I not convinced that in any circumstances – or particularly plastic boxes need to be changed. Yes, the wiring glands should be tight and no unprotected live wires. The reason to change is the risk of fire but the plastic housing is not the risk or cause of a fire it is the wing installation itself! Further, the plastic is a non-conductor so if there was a wiring/poor earthing issue touching the box would be safer than a metal one poorly earthed say (I assume metal boxes have to be earthed).
So the plastic box has a risk of fire. A metal box has a risk of electric shock. Neither is a risk if properly insulated and maintained.
To me, it should be a C3, not a C1?
