Installing new shower. Trying to work out wether the exisisting cable is big enough the cable is ran through a stud wall with no insulation into the loft then through approxx 100mm through rockwool to pull cord then cable from switch to shower in stud wall with no insulation.
Which referance method would I use?
I'm using referance method B as over 90% of the cable is installed in a stud wall without insulation
