Hi, I have just looked under a kitchen unit where I can see some 2.5mm cable that is feeding a 13A fused Spur. It looks as though some of the insulation has been chewed off in a few places but none of them breaking the coloured insulation on the individual wires. What is the best course of action ? I believe some people put insulation tape on the affected areas ! Is heatsrink an option on affected parts ? It doesnt seem practical to replace the cable back to the supplying socket as that is in the wall behind the unit and in parts under the tiling. There has been no sign of mice since we have had the mice so this probably happened when the house was previously owned.
