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.....

    Will it thereafter be accessible - a chance a fitted carpet gets laid?

    Hello Farmboy,

                                 no carpet will be laid. The floor is bare wooden boards now. If the removable TRAP was to be carpet covered, I would have written on it in pencil ELECTRICAL TRAP. I didn't do that as it would have spoiled the floor's appearance. The owner is aware of the trap.

    Hi Zoomup


    Thank you for clarifying your particular example.


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


    Cheers

    Hello Farmboy,


     the use of the big junction/joint box was essential to extend a short damaged cable to allow for reconnection to a new shower ceiling switch. I consider that the new connection is permanent and needs no inspection or future regular access. Junction boxes have been hidden under floors for years with no problems. I do not use junction boxes in new installations or in rewires if possible. There should be no need, but in repairs they can be very useful. I always used to screw down traps in floorboards and mark the trap ELECTRICAL TRAP. This allowed for future access if necessary. But was rarely if ever needed. The full details need to be known before any professional body comments upon hidden junction boxes.
