    I believe this is the case, yes.

    EICR. Cu "armoured" 3Ph supply cable. Is this a thing?

    It was installed in ~ 1989. That would have been 15th brown book, but I don't think that affects anything. I'm not sure if ESQCR had anything different to say back then. Substation in a building on the domestic site. Original contractor no longer trading. No information otherwise.

    EICR. Cu "armoured" 3Ph supply cable. Is this a thing?

    Definitely concentric. Not split. I'd hesitate to call it P"M"E because there is definitely no opportunity for any multiple earths this side of the substation.

    EICR. Cu "armoured" 3Ph supply cable. Is this a thing?

    I was tempted to call it "concentric". I'm only previously familiar with domestic 1 Ph supply TN-S which splits N & E on the outer.

    EICR. Cu "armoured" 3Ph supply cable. Is this a thing?

    I've come across a DNO installed (SSEN) 3 Ph 3 core PNE supply cable from a private substation to a large Lucy domestic head. Cable 3 Ph is copper "armoured" (or is there a better name for it?). Entirely underground, entirely within a domestic single owner property. No obvious practical or...

    EV chargers load curtailment & remote Ct. Recommend me a brand?

    OK, that seemed straightforward enough. (Having checked Zapi 2 in more detail). I note your comment about the Harvi 65A limit for wireless and checking this on website agrees. 60A set it would be fine though. My outstanding concern about the range is (partly) eased by your 40M experience. I used...

    EV chargers load curtailment & remote Ct. Recommend me a brand?

    Hi Gavin. Thanks for the quick reply. I know of Myenergi and have looked at their products in the past, but not for a while. The Matt:e (strange name) is a brand I have never come across so thank you for the quick pointer. Without much spare time, I might be away for a little while here...

    EV chargers load curtailment & remote Ct. Recommend me a brand?

    Can anyone recommend an EV charger brand/type with load curtailment (throttling) which is easy to interface by manufacturers design, with a remote Ct clamp (via radio link)? Situation as follows: Customer in 18c manor house converted to flats, living third floor. Supply head is ~ 35M away with...

    Calibration Costs?

    Did Rexel give you a turn - round time on that? My local Rexel has more or less shut their doors. I "stretch" a cal out to a couple of years with regular test-card checks etc, but with everyone closing their doors and insisting on mail-in of instruments that's got difficult. This is the...

    Please suggest a reasonable quality white euro-module brand

    Well they're a bargain price if they work well

    Please suggest a reasonable quality white euro-module brand

    I don't do much data cabling. I fitted recently CAT6 using TLC budget "Kauden" brand euro modules and plates. No problems with the module connectivity, but they were sloppy in the default frames and the frames were really flimsy and nasty sharp cornered thin plastic. I needed a lot of care just...
