Domestic PME, Radial socket outlet problem

freedomrun · Mar 29, 2012

Domestic PME, have two 2.5mm t&e on a B32 mcb, if this was a ring at sometime then the continuity is broken somewhere and i cannot locate the break. No access to underfloor, no spare ways in the CU, has RCD protection to 30mA. I'm thinking it is not compliant to put two Skt Radial cct's on one breaker even if i downrate to B20? Any advice on what to do here please. Thanks.

What have you lost continuity on? L N and E ? or just one?
depending on what you have lost continuity on depends on the test you do to find it. as others have said you need to find the last socket before the break and disconect it at both ends! but you may also find the fault when doing this.. but it goes back to asking what have you lost continuity on?

I have no continuity on cpc, L & N. My apologies - I should have stated this in my original question. This is also why i'm not sure if this cct was ever a RFC in the first place.

Disconnet both legs at CU. Link R1 and R2 at board, on one legs, go to each socket in turn and check the reading, Do the same on the other leg, then see if the 2 "loops" are close to each other. Inspect connections at each "end" you have identified and see what you find
