Stem, you hero!
I was going to take the isolator apart.
Though after your help I traced the mains back to a cupboard, which had the spur inside. I’ve swapped the fuse and can now take a shower.
Thanks ever so much.
Hi all,
I need to check to see if my boiler has blown a fuse. I don’t seem to have a spur. Only the box attached. Is the fuse within there?
Hope this finds you well and thanks for your help.
