Hi can anyone offer advice?
I've been to look at a a consumer unit change. The head is antiquated. it wasn't sealed so I tried to pull the cover off but it was stuck. I eventually got it off and there was a porcelain fuse carrier underneath. This has been stuck in with bitumen. The Line cable from the head to the meter is 16mm double insulated but the neutral from a seperate box is a cloth covered VIR.
Can anyone
A. Put an age to the head,
B. Suggest what the fuse type and rating is, and
C. Is it possible to issue an installation certificate without the head being changed?
Thanks.
