Evening all!
Just completed one job for my DIS scheme. Planning on changing my nans CU for the other. Went to have a look the other day, not as bad as what I thought! No bonding in place and earthing conductor too small but gas and water right next to meter so all easy fixes. The board itself is the old wylex rewireable fuses, little bit concerned that it only has 4 ways for a 3 bed semi. One supplies garage (30A). One lighting circuit (5A). Two power circuits (Both 15A). I havent taken the unit cover off yet, but I can see it has one 6mm T+E , which I assume is garage supply. 3 2.5mm T+E, guessing either 1 ring, 1 radial or 2 rings (other cable perhaps runs behind unit?) and 2 1mm T+E for lights.
Supply is TN-S.
Look like 16mm Tails. Cut out fuse isnt labelled and is actually damaged, top casing is missing about 30mm round plastic, quite easily stick my thumb in and touch the brass inside, so will be informing DNO first thing tomorrow, need to fit an isolator and upgarde tails anyway so hopefully that will make them come out faster!
So heres the plan!
New board 8 way board for any future re-wire. Going to have a look at breaking the lighting circuit into 2. Its been wired as a ring so hoping I can remove the cable that joins upstairs to down and put them on 2 radials. Im not sure about the ring(s) yet, if it is 2 rings wired in 2.5mm T+E, is it worth sticking them on 32A or out them on 16A's? I cant understand why theyre on 15's atm which makes me a little suspicious! The garage unit im going to replace at the same time as its a similar board but its missing half the side of it so needs replacing. Its fed via 6mm clipped direct then runs over head. Wasnt sure whether to install a 2 way with RCD in garage or put it on one of the RCD's in the house? Im going round there first thing tomorrow to do Ze test and some quick IR tests as its not currently got any RCD protection.
Also last point, noticed 2 or three old wylex switches in her house, ones and isolator for garage, anothers for outside light, they look pre-historic, green metal with black plastic for the switch. Are they acceptable as long as theyre earthed or do they need replacing?
Any suggestions/help much appreciated as always!
Cheers,
Rob
