i am about to change a consumer unit and will therefore need to upgrade the tails to 25mm and the main earthing conductor to 16mm...only problem is that i will have to cut the seals on the meter if i am going to do this...ok,now that i have cut the seals 'and now i will be sent to jail!!!!!' on the meter and replaced the tails!!!,am i now going to have to cut the main fuse to replace the tails from the fuse to the meter as these are still 16mm?if i dont there would have been no reason to change the tails from the meter to consumer unit!!!!!!
