Since we had our extension built we have had continual problems with the isolator switch for the shower becoming really hot. It’s been replaced a few times. At the weekend, the whole hose was plunged into darkness and there was a puff of smike in Emma’s bedroom. One of the carers burned her hand switching the shower off. We were out of options until I read Larry Adkin’s guide, then I realized I needed professional help.
A call to a friendly electrician revealed the source of the problem above.
Today the electricians from the builders arrived and completely re-wired the shower and replaced the main breaker.
Speedy service !
