Firstly let me explain the current circuit
10KW shower - 10mm2 cable to 50A Pull Switch < 5m - 10mm2 cable to CU 16.5m - 45A MCB - 30mA RCD.
The problem is the one piece 16.5m 10mm2 cable is about 2-3 m short for a neat installation around the CU. it could do with a short section to be joined onto it to then run into the CU.
A) Is this a good idea? the junction can be hidden under floorboards, or exposed for inspection. is joining 10mm cable a good idea? the 16.5m length was the longest available at the last minute. it's well below the 25m i have since seen available
B) if it is ok, what do people recommend for joining such things? i know it's far from standard practice, but there must be an acceptably safe way of achieveing it.
Cheers
