Changing Damaged CU

[skippy2]

Got a job coming up where customer has damaged CU, can't get identical CU and cabling to short to fit in new cu and customer won't pay for rewire.

Whats the best way to extend cabling to comply with regs?

Through crimp and heatshrink

Forgot to add, you could put a peice of 100*100 trunking above the new cu to put all the joints in. this way if they are needed at a later date you have acsess to them

If the joints are inside the new cu then just use crimps, they add very little 'bulk' as they are 'in line' and no need for heatshrink or other covering.

i'd use crimps as they are small and don't look too untidy inside board

Just a quedtion to the crimping fans, do you stager your crimps or jus as you cut thr cable?

Skippy, what exactly do you mean with " cabling too short to fit in " ?

Do you mean they won't reach the various terminals in the new board ? It reads like they won't reach the board at all .!!

Depends on the end result required. If it's just cables inside a cu then I just extend each conductor as necessary. If it's outside any enclosure and a slim joint is required (for looks or burying) then I stagger. If it's just going under a floor or in a loft I just cut it square.

Is it not possible to move the CU slightly higher (or lower or whatever) to make sure that there is enough cable to terminate properly?

The excess could be made up by using slightly longer meter tails, this will be much quicker and you will be able to dress cables into new cu properly.

If you can't move the CU then it is rare that none of the cables will reach, it usually the case of only having to extend a few.

I stagger the crimps by telling them a joke.................. :coat
