I’ve just had my incomer fuse upgraded by UK Power Networks & It was mentioned that my meter tails should really be uprated to 25mm. How do I go about getting Bulb to do this? Is there a cost involved or should it be done as a matter of course if it is a safety concern?
Ring them and ask them to upgrade them - it could be free.
If you have had your main cutout fuse upgraded that is because you expect to use more amps. So it is a safety concern.
