60 Amp Junction Box.

Zoomup
Mornin' All,

                      I came upon a burnt out terminal on a Crabtree ceiling 50 Amp. shower cord switch yesterday. The cables had become so hot after 3 years of use that the line P.V.C. had completely fallen off the conductor and had left a horrible black smelly sticky mess.


I had to replace the shower cord switch, but the damaged cable was then too short after removing the softened copper and damaged insulation.


So I had to make a trap in the room upstairs, which turned out to be wooden boards over other wooden boards to access the cable below with a view to lengthening one cable. I used a new 60 Amp junction box as it allows two large conductors to overlap and be secured by 4 screws. It is solid and of good quality.


It is this item.....

    I asked the NIC about a screw joint box under fitted carpet and was told that could not reasonably be considered accessible.




    It also leaves a bump under the carpet, and may be a trip hazard. However it is accessible with a Stanley knife if required.

    Joking aside the bigger problem with anything like that under boards covered by a carpet, lino or whatever is not really accessibility, so much as knowing where it is . in the future, when the notes have been lost.

    If you do not worry about inspection, and I suspect in reality most folk do not open every junction if everything checks out OK, then generally you only need to get to it when there is a problem  and then, like finding a damaged section of cable, if you cannot find the problem,  you may choose to isolate both ends and run a new route around it.

    I have done it the other way up and used a plasterboard mounting box and cover plate in the ceiling below as a inspectable location
