Hi all I'm after some advice on 2 way CU in a garden office which is 'buzzing' when I turn on or increase the tempreture of the wall mounted heater. But it only buzzes for a short time and then stops.
I'm not a qualified spark but confident enough to have double checked the torque settings on the mcb's and visually inpected everything including the buzzbar for any signs of damage etc. The CU and circuits were only put in roughly 4 years ago (by a qualified spark) and tested but the heater itself is about 12 years old.
Could anyone give me any idea on what could be the issue please and more importantly is it something that needs urgent attention or can it wait until the new year?
Thanks Paul
