I've recently had an electrician in to sort out why my RCCB kept triggering when I put the Ring Main CB on..............the exact cause was never found although a certain part of the Ring main was found to have a low Resistance reading (Less than 200MOhm ?) & when this part was included in the ring main it triggered the RCCB.
So when I asked for a 5 year Safety Check (prior to the above work) I was told that it couldn't have 5 year interval due to the Low Resistance on the ring main.................so wouldn't it of been the answer to cure both the above to "recable" the portion that had the Low resistance / Triggered the RCCB ?
Secondly & a bit more worrying is that the ring main is protected by a 32A CB but from this ring main is a Spur which is in effect a radial circuit.......this radial Circuit is in the kitchen with 7 sockets/ fused outlets from it.........
So am I right in saying that this number of sockets should not be a "Spur" which infact is a radial circuit ?............plus the fact that this is 2.5mm cable Radial in a kitchen........& with a Dishwasher, Washing Machine, Kettle, Toaster & a 2 KW Heater all possibly being run off this at one time this could exceed the 20A of the cabling & not trigger the 32A CB !!!
