Re: 1970s Wylex double-pole isolator switch M131/2
16mm2 is bigger than welding cable, not ideal for any house stuff. The OP is likely to have used a vernier to measure it, it will show In the region of 6mm measured across.
Shower cable is supposed to be 10mm but that is big enough to start a lorry engine!
It would be advantageous to know exactly how it is being measured.
