Been out of game for 2yrs due to illness so a bit rusty and would be gratful for advice.Cu change for Part P assesment.Cant touch decor to much, inlaws house. A few problems caused by diyer.
1.16a mcb with 3 seperate radials . 1 feeds 1x1g skt other 1x1g skt other 1x2g skt. Going to split into 2 radials in 16a + 1 radial in 16a.
2. 16a mcb with 2 seperate radials. 1x1g 1x2g in kitchen.OK.
I know its bad pratice and not standard circuit (but i think its just same as spuring of a radial at any point )Not against regs and will be ok for assesment if label up at cu and noted on cert. But 3 in 1 again bad pratice better split into 2 and 1.
3. Shared neutral on landing light, usual thing fed from down light. Neutral from up. Going to run sheathed single in existing trunking to loft to landing light to solve trip prob.ok.
4 .2g skt directly behind electric cooker at low level is this ok. Not sure again think not against regs just bad practice.
5.Shower 9.5KW fed by 4mm!!!.Upgrade to 10mm luckly 4mm is already in trunking on landing to loft cu under stairs.
6.Garage 20a mcb from house cu 2.5 2c armour.To 2way m/clad cu 6a 16a Problem being old freezer which trips rcd.1 light 2 skts. Going to remove rcd at cu in garage change skt to rcd type and have freezer on m/clad unswt fcu.New house cu high integrity with garage on main sw side no rcd.ok.Yes pme but no extreneous parts, water pipes eg, in garage so ok. though you may not agree
.
7.Rest of house skts mix of 1g and 2g 32a mcb rfc feedin 14 points.Not best but ok.
Two Cus at present right mess main old wylex m/c 2nd added for the radials above and shower which is piggybacked form main switch in 10mm cores chopped of to get in terminal with tails At least its rcd which was a suprise, again right mess.
Your advice and views please. Two years out can knock your confidence a bit.
Thanks neil.
