Hi everyone, i might be having to run new meter tails from meter box to consumer unit which is just under 3m run, i have used 25mm 3 core before and its hard to work with especially through joists. I was thinking about 2 core 25mm swa and a seperate 16mm earth to make life easier but then came to the problem of having to run all 3 cores through the same hole due to eddy currents when terminating, does anyone have any ideas on this or is it not possible? Thanks for reading
