[Johnathon]

Hello
Just after bit of advice, just connected up a shaver socket in my bathroom and when plug in electric toothbrush there is a quiet humming noise coming from the socket, noise stops as soon as toothbrush plug pulled out, is this normal, cheers

Best asking a sparky to test it really mate.

Is the socket output reduced to 12v or 24v? If so then the noise is probably just the transformer stepping down the voltage.
