A bit ago I asked about using a disused immersion heater switch (protected with a 16 amp mcb on the circuit board) to run a cable into the loft for a double socket. I opted for a fused connecter (13amp) and ran a 1.5mm (16amp) cable 5 metres into the loft to the double socket.
Is the 1.5mm cable ok or should I have gone for 2.5mm?
