Hi all, this is a question regarding my sons 45 Amp pull cord switch located inside his bathroom.
We are now on our 3rd switch in three years. The original one that was already in his flat lasted 18 months, this was already in when he and his girlfriend moved in. When it packed in I got my friend who is a qualified electrician to replace it for me, we managed to get into his loft to release more cable down into the bathroom, it was cut back to clean wire and a new one fitted, this lasted a year or so and the same wire had blackened and burnt out again. Its always the Black Neutral Supply cable that keeps going.
I then replaced it myself with another 45Amp switch, made sure all the connections were as tight as possible without stripping the brass connections, got my friend to double check it and again this only lasted a year before the same thing happened. I have now fitted a 50Amp MK switch to see if this helps.
Now here is my main question, I just asked my son how long he takes in the shower, his answer is a whopping 15 to 20 minutes then his girlfriend has a 20 minute shower straight after so its constantly under load, this is every day, we are talking 30-40 mins. I know these swtches can get warm so my theory is its not getting a chance to cool down and 30-40 minutes on every day means its not getting warm, its getting hot although Ive not felt it after 40 mins use. Im thinking its is going to burn it out eventually.
Am I talking a load of bull or is this too long. Ive told him to cut the shower time down to 5 minutes each. Any ideas if this could be the problem or is there an underlying fault elsewhere.
Thanks in advance everyone.
Steve.
