    Lollipop circuit on a 40A RCBO

    Thanks for the practical reminder of the application of Ohm's law.

    Lollipop circuit on a 40A RCBO

    From first principles I would interpret that a 40 A OCPD might be acceptable on a 2.5 mm² RFC or lollipop circuit, if the CCC of the cable allows. I am open to correction but it seems to me that BS 7671, TABLE 4D5, would allow 2.5 mm² T+CPC cable and a 40 A OCPD to be used 'clipped direct' for...

    Lollipop circuit on a 40A RCBO

    My reading of the Electrical Safety Council's guide on the matter is that if the OCPD rating is too high to provide protection to the cable then your coding is spot on.

    Ring main help

    It certainly makes things challenging on the volt drop and circuit resistance for effective ADS!

    Ring main help

    Surely, if redundancy with maximum coverage is required, then 4 circuits that don't follow the whole perimeter would leave large portions of the perimeter without coverage in the event of a fault. If the cameras are intended to watch the inside of the perimeter then this may not be a problem as...

    Earth and bonding cable checks-any tools available?

    Thats a hell of a waste of good Nordic timber!

    Voltage Drop

    The OP did not mention a motor; post 2, not from the OP, introduces the motor presumably as an example to examine what impacts voltage drop ...

    Just a hypothetical question,

    ... I thought that the death penalty was being discussed in another thread ... thanks trev!

    Last day

    Well done Pete, I wish you well in your future endeavours! I hope that you have a worthwhile pot to keep afloat and to enjoy your latter years.

    Is it just me?

    Some leave me quite encouraged that I have something to offer ... and that as a ... I am not quite at the 'bottom of the dung heap'! That said ... I quite agree that even from some supposed 'sparks', the standard is scraping through the bottom of the barrel!

    Solar and Wind

    Google the Beaufort scale, there are descriptions of observable effects of different 'bands' of wind strengths. Also take a look at the Meterological Office web local 5-day forecasts; there is usually a link to the observations of actual weather conditions at your nearest weather observation...

    ... 'motor turned on' ... what motor?

    Prizes for opinions again!

    There'll be accusations of a mutual appreciation society ... people will talk!

    Come on now T, I will have to start referring to you as 'generous' Mr 'T' before long!

    Prizes for opinions again!

    Big belly laugh ... we have something in common there ... I fear. Though in my own case I question from time-to-time how generous I really am ... not everyone has the same opinion of me as I do ;o(! I try to work on the premise of 'To give and not to count the cost ... '.

    I think that there is a bit of 'pyramid' selling 'amplification' going on here ... you got yer like n thanks!

    ... Dilligaf? How so ... 1 like and thanks each doled out and multiple in return? Then maybe I don't understand the system!

    Prizes for opinions again!

    ... and there was me thinking that you were doing this out of the goodness of your own heart ... not trying to bump up your stats! ;oP

    Need some advice with Garage lighting.

    Does that mean that I can blame my multi-function tester when it doesn't give me the result that I want?
