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.....

    In this article they nod to the issue of interpretation of accessible.


     



    I believe that the wiring regulations have always required joints and junction boxes to be accessible for inspection or possible future alteration. Junction boxes should not be hidden in walls and plastered over as I have found on many occasions. A box and blank plate would be a better solution if the customer allows it. The Regulations for the Electrical Equipment of Buildings 14th Edition revised up to 1976 in Reg. B.73 requires joints in cables and bare conductors where necessary to be mechanically and electrically sound. Joints in non-flexible cables shall be accessible for inspection etc...
