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.....

    Chris Pearson:

    As for the use of screw terminal as opposed to (MF) junction blocks - are the latter available for greater than 6 mm2 cable; and if so, are the enclosures rated for the current?


    So you may be stuck with traditional junction boxes.




    Are crimps and voltage rated heat shrink not acceptable?

    I would consider crimps on a 40 Amp shower circuit cable a "no no." The 4 screw per terminal 60 Amp junction box that I used is much much better.
