YEDL have just installed a new PME earth in our house. I'm about to install a new CU, but want to check something first.
The current CU is an old Wylex wired fuse job, fed by about 8m of 6mm T&E, which scared the life out of me when we found this out (only bought the house 3 months ago) because there are a number of high power appliances installed in the house. This is protected by a 63A switchfuse (although I haven't checked the fuse rating in it TBH) next to the meter. I assume this is there because of the distance to the CU as much as the under sized feed. The new CU is going next to the meter so I want to ditch the switchfuse because it's only 63A.
The tails from the meter to the switchfuse are too short to feed the new CU directly so I need to extend them, and I thought I could either use a couple of henley blocks to join them (do the DP blocks mean I can just use one?) or mount a 100A isolator module in a single module enclosure (Screwfix 32311).
Which would be the recommended method?
