I've just had a new bathroom installed(UK based) and the electrician has put two shaver sockets(110V and 220V outlets) and an extractor fan on the light circuit.
With two toothbrushes plugged into the shaver sockets, the extractor fan lasted about 3 weeks before buzzing and then completely failing(but still buzzing) after about 4 weeks.
I've had a few electricians around and they all seem in doubt as to what the issue is - was it a freak failure or did the two shaver sockets destroy the extractor fan?
The extractor fan has been replaced, but I'm not using the two shaver sockets at the moment as the buzz is quite loud when both are plugged in. With only one plugged in there is only a mild hum.
Does the extractor need to be on a separate circuit?
