60 Amp Junction Box.

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.

If you asked me, I'd say that if you gained access to the location to install the JB in the first place, it can hardly be regarded as inaccessible. Of course, things might change in the future - being tiled over or covered with glued laminate - but that's a slightly different question.

I tend to concur. It's a pain in the bottom, especially if the boards are T&G, but isn't lifting boards part of the deal?

IIRC, there was an article in https://professional-electrician.com by somebody from Wago which argued that under the floorboards is not inaccessible.

If, however, the sub-floor is sheets of board glued into place, followed by wet under floor heating, and then more boards, perhaps with a decorative or durable finish, nobody is ever going to go through that. Under those circumstances, I have made it clear that should any attention be necessary (presumably not with (MF) equipment) the only way in will be through the ceilings.
