Replacing Junction Boxes

[RussellS]

Hi,

In the precess of doing general renovations to the house I have come across a few junction boxes under the floorboards in both the ring main and the lighting circuit.

What I want to know is whether I should be removing these junction boxes as I find them and joining the wires using either crimps or soldering. Obviously, being under floorboards they are not open to inspection.

Also, in this forum there appears to be differing opinions about what is the best way to join the wires together. What are the pros & cons of both crimping and soldering. I understand that when soldering you need a good electrical connection before applying the solder and that the solder itself should not be providing the electrical connection but just holding it all together.


Many thanks for any advise.

Russell

best advice if not faulty is leave them

Do away with the need for any junction boxes at all by replacing the cables, making all joints in sockets / switches / fittings, so they will always be accessable?

While this may be the ideal solution it is not always possible when the wire is in an area that is decorated or has floor laid.

I am perfectly happy with the "if it ain't broke don't fix it" philosophy. However, what if there is one that is broke and does need replacing. Should I then replace with a new junction box or join the wires.

Replace with through crimps (blue on the live cores, red on the CPC/earth) and heatshrink over the entire lot. It will be neatest if you stagger the crimps to avoid a large 'bunch' in the cable.

Thanks very much for the reply.

Unless of course the jb's join more than 1 pair of cables....

So what do you do in this situation?

Check the tightness of the screws and put back under the floor for another 20 years or problem free electrics.......?
