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 am surprised nobody has mentioned soldering yet? Is this a dying skill? It really doesn't take very long with a decent setup, and if the joints are well made, it's as good as the original cable.

    I like the idea of crimping on lugs and then soldering them as well. The initial crimping holds the lug and the solder fills any voids afterwards and reduces the possibility of corrosion. . A small hole in the lug allows air to escape when soldering. Lugs were soldered on years ago for connection to bus-bars etc. It is not a good idea to solder on fine stranded wires as they can break due to any vibration in vehicles or vibrating machines though.



    I certainly haven't had problems with soldered connexions in motor cars over the years, even battery cables.


    However, we must be mindful of 526.9.
