Yesterday I was adding some supplementary earth bonding to the shower switch in my bathroom, and discovered that the end of the supply live wire had blackened and partly melted the terminal in the switch.
The shower is 7.5Kw, 18m from the consumer unit. It is cabled with 6mm, protected by a 40A mcb and a 45A double pole pull cord switch. All other terminals are ok. The cable is not laid within any insulation in the loft or adjoining walls. Any ideas why this may have happened? What can I do to ensure that it doesn't happen again?
Thanks.
