    Ring circuit fault issue

    Hi. Had a guy in yesterday to look at the tumble dryer and he told my wife he couldn’t work on it because the ring circuit of the house had a fault showing on his meter of over 2 ohms. Wasn’t quite sure what this meant but I’m taking it as neutral to earth leakage??? I don’t really have any...

    Calculating Cable Size for Ring Circuit

    Hi All, I'm needing to calculate the cable size for a long ring main. Cable type will be SWA/LSF. The ring is feeding 5no Twin Sockets, on a 32A Type B RCBO, kicker is the length out and back is 300m. Using cable calculation tools can i half the length, 150m, half the current, 16A and allow 20%...

    Ring circuit or radial . Is this positive

    I was talking to 1 of the QSs today and was told that in amendment 1 of the 18th he thinks it will say about going back to doing radials rather than ring circuits. I'm not sure how true this is but the guy is friendly with NICEIC people and seeminly this was discussed at a recent road show (...

    Crossover in ring circuit

    HI, as my profile says I'm not a sparky and know my limitations. I'm trying to learn (for the sake of it only as I'll never do it) what tests for "Ring Final Circuits" are. I understand how the Tests 1, 2 and 3 are done but in one of the videos I watched the presenter (John Ward) mentions a...

    13a Fuse Spare spur from ring circuit

    Evening! I've got a 32amp MCB under an 30mA RCD supplying a ring of sockets in the basement. There is an electric heater that the client wants hardwiring in (still needs to have a switch). My logic would be a Fused Switch. Can I take the spur from a near by double socket into the input?

    Testing

    Does it matter which method (method 1 or method 2) you use when testing for continuity of the circuit protective conductors? Or is each method dependent upon which the type of circuit you are testing on ring or radial? I have been told that test method 1 is used for lighting and radial...

    Continuity Tests

    Is the continuity test for circuit protective conductors, the same test for ring and radial circuits or is there a different test for each type of circuit? Also what is the difference between testing for cpc continuity and testing for continuity for ring final circuit conductors?

    R1 + R2 of ring circuit

    Hi for a ring circuit, is there any need to measure and enter R1 + R2 values on a schedule of results ? Because an r2 value is already measured (together with r1 and rn). If I needed a ring R1 + R2 value to calculate ZS (although i would find ZS with a socket tester so really no need; but if I...

    Kitchen Mains Circuit?

    I live in a dormer bungalow, we only have one ring main which supplies both upstairs and down. We are about to installing a new kitchen and initially got a quote from B&Q, the installer came round and said that B&Q will insist on making the kitchen into its own ring circuit (to secure the...

    4 core fp200 ring circuit

    Came across a 2.5mm fp200 4 core cable used as part of a ring today, am I right in thinking this isn't an acceptable method as there will be only 1 earth wire in the cable ??

    Solar PV supply taken from a 32 amp ring circuit. Is this acceptable?

    One of my domestic electrical customers has recently had a 4Kw solar PV system installed. The area in the garage next to where the array was located does not have easy access to the main Consumer Unit so the installers have installed a 2-way garage consumer unit to connect the inverter. This 2...
