Soldering t&e

Vote4Napoleon

Hi all,
What are your opinions on soldering together L-L N-N PE-PE of a 10sq, 6sq and 2x 2.5sq t&e. Basically 10sq feeding from db 6sq to hob and 2x 2.5sq to 2 ovens. It's on a 40a mcb and the ovens supplies will have 13a sw. fused spurs protecting the ovens. Kitchen supply was pulled before any design of the kitchen cabinets and as is often the case an addition has occurred (extra oven). Thanks in advance.

My opinion is it's dangerous.

Thanks for your reply. What way would you go about it? 63a connectors in a jb?

It's dangerous because you will have 2.5sq cable "protected" by a 40MCB.

Even the 6sq isn't adequately protected by a 40MCB.

No competent electrician would do what you are suggesting. You should not "join" various cables, the method of joining is irrelevant.

Just remember the cost of doing this job right is far less than the cost of when if goes wrong as you might find your insurance invalid, of course your losses potentially may be much worse than just financial.

Thanks again for your response. I was thinking of fused spurs before the ovens respectively so that the 2.5's don't draw a dangerous load.

To be honest I don’t follow what you are saying. Please explain again.

I will say this:
There are lots of acceptable ways of joining cables such as this. Soldering isn’t one of them. The trick is to ensure that every section of cable is protected by a suitably rated protective device. This may be achieved with an MCB or a fuse.
