    How tolerant of customers are you?

    It’s all been said but boils down to new customers work to my terms and timescales or get politely told to find someone else. I’ll put myself out for long standing loyal customers. Yesterday at 4:40pm the caretaker of a community centre called me. I’ve worked for them for years. No lights in...

    Distribution circuits in Section 705 location, RCD needed?

    So far every C3 I've issued has been actioned, so it could well still happen. I'm intending to C2 the livestock access to distribution panel /cables and access to hookups as I consider them more potentially dangerous. But before deciding on the remedy I need to declare how dangerous a cable 1.2m...

    Distribution circuits in Section 705 location, RCD needed?

    Let's not get into a debate about whether 705 applies, for me that is without question as for at least 4 months of a year there are sheep in that there field! Here is where I am at: That locked cabinet is the outer cabinet. Inside is a further metal distribution panel with a locked door. It...

    Antique motor wiring

    Right, so centrifugal switch, two coils, and a start capacitor (google 80 micro farad start capacitor) There are lots of diagrams online showing you how a single phase motor with start cap and centrifugal switch is wired up.

    Distribution circuits in Section 705 location, RCD needed?

    Ok photos. The distro box D The more concerning hook up point (the mobile units go before the sheep arrive)

    Distribution circuits in Section 705 location, RCD needed?

    I'll take some photo's tomorrow or maybe tonight as I've been dragged there for other reasons. If we decide the cabinet is 'inaccessible' to animals, and the cables underground are, well, underground, it remains the case that there are distribution circuits supplying points in the field that...

    Distribution circuits in Section 705 location, RCD needed?

    SWA is TNCS, isolated at point of entry to other cabinets, then TT. So no requirement for RCD for fault protection of cable if that is what you were getting at!

    Distribution circuits in Section 705 location, RCD needed?

    Thanks @loz2754. Out of academic interest, you are right about the reason. Having just read the 16th edition equivalent section it's basically the result of simplifying many very complicated regs about EEBADS, protection from indirect contact to exposed conductive parts, and requiring reduced...

    @westward10 I really appreciate your thoughts. Thanks.

    Distribution circuits in Section 705 location, RCD needed?

    ...and that is the thing. I don't think the RCD bit is actually a problem in the real world at all. I want a C3.5 - "Improvement NOT Recommended but I've noticed it"

    Distribution circuits in Section 705 location, RCD needed?

    Yes. Quick sketch: Distro cabinet D has no outlets, it's a metal distribution panel within an IP rated box mounted within a timber 'bus shelter' style structure. Enduring question is whether D being inside the field mean outgoing distribution circuits need 300ma RCD protection. Other concerns...

    Distribution circuits in Section 705 location, RCD needed?

    :-) Not quite 6 circuits, similar to this: https://hager.com/uk/products/h/hda100u-mccb-h3-x160-tm-3x100a-18ka

    Distribution circuits in Section 705 location, RCD needed?

    Thanks for looking through it. My take is that it's a circuit in a location covered by 705 and needs RCD protection. I still believe the intent of the reg is fire protection in buildings, not distro circuits buried underground. This distribution box is a massive Hager board with x160 moulded...

    Distribution circuits in Section 705 location, RCD needed?

    Mainly TNCS. One set of hook-up points is definitely TT'd. I'd need to check the other but I believe it is much higher and connected to supplier earth. I'd also comment that Section 705 didn't say quite what I thought it said about that. It says it shall not be TNC (combined and never...

    Distribution circuits in Section 705 location, RCD needed?

    I just want to check how I should be interpreting section 705. 705.411.1 states required disconnection devices, the first two indents covering final circuits and sockets, requiring 30ma and 100ma RCD's depending on rating of socket. Indent 3 says " all other circuits" need 300ma RCD. Does that...

    Misuse of Quickwire plug and socket

    Aside from their intended use on lighting circuits, a while back it occurred to me that they make quick and simple test adapters. I wait for various commando plugs to come up cheap on ebay and then do this to them. My collection now stands at 16A (3,4 and 5 pin) and 32A (3, 4 and 5 pin)...
