    EICR code - type C breakers with undersized CPC

    Mainly on commercial lighting with twin and earth 1.5mm or 1mm on 6A and 10A type C breakers Im sure there was a table in bs7671 requiring larger CPC sizes for type C breakers than supplied with twin and earth, hence why people use fb200 or singles etc I guess it must be restrictEd by let...

    110 V between L and CPC

    I am in training and decided to do some dead tests using my second hand Fluke MFT 1653B on an upstairs ring. I did the tests at a socket rather than at the CU. Results end to end L - L 0.74 ohms, end to end N-N 0.76 ohms, end to end cpc >2000 ohms. I checked all the sockets on the ring and...

    Line to CPC ratio.

    Just curious. I'm trying to find a poor connection on a ring circuit CPC by comparing resistance between the lines and cpc. I've chocced them all together at one end at the CU. I'm looking for a divergence between the CPC to line and line - line ratio. What is the ratio of CPC - line compared...

    Best way to check continuity of cpc for lighting

    20 y old lighting circuit with cpc at the board but terminating into class 2 recessed down light fittings. Looks like there is a junction box in the ceiling void feeding the light with L&N but I can't access the junction box so not sure how can prove continuity of the circuit?

    All these procedures for proving dead in the UK are mostly new to me . We were expected to be competent to work safely with the training we were given, I don't recall ever being taught to prove dead as such So is there a set procedure for proving dead in this scenario with approved devices...

    EICR no CPC at light

    Just want to see what people’s thoughts are on this, doing an EICR today. Testing the lighting circuit, 1 cable at every accessory which means joint box somewhere. Hall light is a pendant wired in 2 core PVC cable, no earth at it. Tested at kitchen light and got a reading, then tested at living...

    Neutral to CPC low reading on lighting circuit EICR

    CPC low R2 continuity reading ring final

    Hi, I've just been testing a ring final before installing an outdoor socket and I got an R1 and rn of 0.6, but instead of 1.01 for R2 I got a range of readings from 0.1 to 0.51 and it wouldn't settle down, so I couldn't continue the tests. I know parallel paths could cause a low reading, but...

    No CPC on lighting circuit

    No CPC at switches or light points. All lights are class 2 so a C3 on eicr. But what do I write for r1r2, just a LIM? is that acceptable? bit confused on this.

    Here's one I wasn't expecting on an EICR. Recently rewired and renovated 2-bed property (2015ish). Having an EICR as a new tenant to move in soon. No reported problems. I expected to be in and out in about 3-4 hours to be honest, and as expected I found nothing wrong until I began my ring final...

    Round Up or Down When Selecting CPC

    When selecting a CPC, do I round up or down? For example, if I have 120mm2 actives do I select a 50 or 70mm2 earth? If a have 150mm2 actives, is 70mm2 enough?

    Borrowed CPC for water bonding

    I've come across a house whereby the redundant immersion heater circuit (15A) has had it's CPC repurposed as a means of bonding the incoming water supply in the same cupboard. Irrespective of the CPC being undersized is this, in theory, allowed or must the earth bonding be clearly identifiable...
