hello I did an EICR today on a flat probably about 10 years old. everything fine except the usual C3s for non rcd protected circuits and for plastic boards etc. my question is has anyone come across the type of cable I found going from 80mcb near cut out to con unit in the flat. at first I thought it was 3 core 4mm swa until I open up the con-unit. Ive been sparking since 2004 and aint ever seen this type of cable.
the brown core is 16mm
there are 7 x 2.5mm blue cores whichs equates to 17.5mm
and theres 4 x 2.5mm bare cores resulting in 10mm
The submain does disappear in to wall so I wanna know if I just treat this like I would of if it was 16mm twin and earth sub main and put c3 down for not rcd protection to cable
this is the first time I have ever posted anything on here so if I'm doing anything wrong please let me know
