    Torque Talk

    When I was with the NIC my area engineer was happy that I had one, and that was the end of the conversation, but, it was a tick on his form. Mind it was a few years ago, maybe the policy has changed, or perhaps my engineer was a bit more by the book. I don't know.

    Torque Talk

    The H&S "bods" in the UK can't understand that people can work on isolated equipment without using insulated tools. However, in their defence, the UK public distribution network is in such a poor state of repair that the PME/TN-C-S system using CNE/PEN conductors is breaking down and there are...

    Using conduit as a CPC

    The old Robin separates are the ones that do this. Not sure what model mine is.

    Using conduit as a CPC

    I once found an earth fault loop fault with a high current loop impedance tester rather than one of the modulated soft testers we use these days to avoid tripping RCDs. That put mains voltage / 10 Ohms down the loop test wiring. So, 23-25A, or there about.

    Using conduit as a CPC

    Right, sorry, the Megger PAT101, I didn't know. A useful thing to think about, IMHO. I use my DLRO for much more than containment testing. Motors, connections, earthing and bonding wiring. The high current high accuracy, DLRO10HD, will give 0.1 micro ohm resolution at the 25 milli Ohm range.

    Don't know sorry, I get the Gold package because of the work I do with the IET. You would have to ask them.

    OOh, Megger 101, what's that? Not familiar with it. Any links?

    Using conduit as a CPC

    Quite, luckily, even though I am too ill to use them, I have a high current PAT tester and a 10A Ductor, (Megger DLRO10X).

    1/2” Course to Fine Thread Adapter???

    If it is French, it is likely to be metric, not 1/2". Though not definitely. How accurately can you measure it, and can you measure the thread pitch/TPI? That way, it can be matched up to the known thread sizes. PG7, which is a metric European electrical thread size, is 12.5mm OD and 1.27mm...

    Torque Talk

    Scam members are expected to use a torque screwdriver for every termination to comply with the terms of their membership. What is done is another thing. On an EICR, it might be expected to check terminations, but the requirements of an EICR are also minimum disturbance. Any new terminations...

    Using conduit as a CPC

    This is why we used to do a doctor test on the containment when using it as a cpc. Shame that has gone out of fashion!

    BS7671 iPhone App???

    The IET have the regs and all of the primary guidance they publish available on an app by subscription, I find it VERY good, and I was an early adopter back in the 17th ed days. You get to have the content on, and offline on 2 mobile devices and 2 computers as part of one subscription log-in...

    different make SPD in consumer unit

    Sorry, @pc1966 I don't know how much they would be. I would have to sit down and work it out. I used to have access to many standards when I was working and doing the design/consultancy/expert witness stuff, but since being diagnosed with stage 4 incurable & terminal cancer toward the end of...

    different make SPD in consumer unit

    Don't shoot the messenger. I didn't say I agreed with the situation. Mind, not all standards would be necessary to be held. Some obvious ones, yes, 7430, 5839, 5266. It could be argued that them being available to buy online and download is, readily available. The cost is something else, but the...

    different make SPD in consumer unit

    The standards are listed in BS7671 and available to buy from BSI, they always have been. Ignorance of the law is no excuse. In H&S law the burden of proof is reversed it is down to the accused to prove their innocence. This leaves the training aspect, and the poor standard of training of...

    different make SPD in consumer unit

    Whilst BS7671 is not law, it is not even best practice. It is the bare minimum considered acceptable. What is wrong here is the "council bod" citing compliance with BS7671 as the reason for wanting this unit changed out. Best practice could certainly be considered as utilising the CU...

    different make SPD in consumer unit

    An SPD does not form part of the requirements to meet the enhanced breaking capacity in the product standard, therefore any brand SPD can be utilised. The "Council Bod" is unfamiliar with the product legislation and standards. Whilst this requirement has been brought into BS 7671 it comes from...

    Wiring a Safety Relay to a Safety Interlocking Switch

    What performance level are you aiming for? It’s whole body access, so Pld or Ple? This is pretty much the first port of call before deciding on how you wire it.

    Three phase motor help

    Just remember that the machine side is nothing to do with BS7671, & make sure that you are insured for 3ph machinery work, controls etc. & design as necessary.
