Burnt Wires to storage heater

[tony]

Hi, Just looked at one of my storage heaters that has decided not to work this year, and found the inside of the spur and the cable badly burned! its been working for a number of years so the wiring should be ok- any ideas please.
Thanks Tony

I would say that the cable in the spur termination is loose so its been arking which obviously generates alot of heat.

As above also reversed polarity can be the cause of this. Regards Jimbo
