Funny that if any one comes on here and asks for some advice on wiring, unless they are a certified 17th edition electrician, they are told in no uncertain terms that they shouldn't work on electrics, yet it is ok for an unauthorised person to illegaly break the seal on the dnos cut out and remove and replace the fuse. Then it becomes a joke. The incomer is possibly controlled by a 400 amp fuse, how many unauthorised electricians use the full ppe to do this? (Nomex boiler suit, rubber gaunlets with leather over gloves, full face visor). Pot and black comes to mind.
