Good evening,
A few years back we had fitted a 10 kw electric shower but the plumber installed without upgrading the mcb (the old shower was about 6kw on a 32 amp fuse). Another electrician said the replacement mcbs for this unit are now obsolete. Is that correct and if so is a new CU required (there are four blank fuseways). The CU was installed late 1990 and uses all mcbs.
Thanks.
