Replacing fuses with MCB's

mcbrien410 · 2006-01-17T21:08:54+00:00

My 25 year old MEM consumer fuse box is still in A1 condition and I'veonly had two fuses blow during that peiod. However I do feel I oughtto update and fit some MCB's.My MEM fuses screw onto the live buss bar and the other side of thefuse takes the wire for the ring main or whatever.Can I replace these fuses directly with a screw on MCB like say thisfrom ScrewFix...MK 16A SP Type B MCB 6kA...or do I have to replace the consumer box to one that just has a clipon supporting rail with the supply main wire going in one side of theMCB and the ring main wire into the output side.T I A Chris.

At that price you could replace the whole CU with a modern split load one including MCBs etc using one of the various special bundle deals that screwfix et al do.

Practically this will be counterproductive, as the work involved will far exceed the time it takes to change 2 more fuse wires.

For sale puposes it wil be ineffective, as what they want to see is a new CU and bathroom bonding. You can do those, but whether its financially worth doing I'm not so sure. To be honest I'd forget it.
