    New Regs regarding RCD's

    I wasn't contemplating that someone would be so stupid as to install a split board in this situation to start with!!!.......

    New Regs regarding RCD's

    I would say that you've been fed a line, there. It's not impossible for an upstream overload device (which I assume is what you mean by 'main breaker') to activate at the same time as a downstream RCD (eg, introduce a load of dirty water and one is sensing a short going L-E [RCD] and the...

    RCBO curve

    I don't believe the OP has specified what rating the residual values are? Because if these are upstream of a cascade they could easily be 100-300mA in which case they wouldn't, necessarily, be affording fault protection. I go back to the basics here that there was a reason a designer decided...

    RCBO curve

    The OP is clearly misunderstanding the three different fault types under discussion here. It’s also unwise to assume that an RCD (or residual component of an RCBO) will disconnect faster than an MCB under an ADS or overload situation - type A & B RCD’s are now often in the >100mS X1n area which...

    open PEN protection.

    Interesting. First things first - a common misconception is that you need to have an earth rod adjacent, you don't - it could be a distance away so consider if a 'remote' rod and cable run (adiabatic ahoy!) might overcome this by conventional methods first before going off-piste. If you're...

    Lucien Nunes - Auction of collection

    And as a sixteen year old lad I worked in a TV shop and used to be on kettle repair duty!! Not only did the elements fail but the classic Russell Hobbs automatic kettle had manufacturing issues with the seams on the spouts and they used to fall off - that's how/where/why I learnt how to silver...

    Distances for supports - AWOL?

    Exactly. So it's even more of a suggestion than a regulation! And another bug of mine is that whilst 7671 itself makes references to all the applicable other standards that it references (easy one is BS1361 etc etc) and even has several pages of tables that list them concisely in the back, at...

    Distances for supports - AWOL?

    D'oh! Just answered my own question - it's me going senile. It's the OSG. As you were.........

    Distances for supports - AWOL?

    I'm either going mad or blind, but I went looking in the brown book the other day to find the small bit where it gives minimum support spacings for cables, horizontally and vertically. Except, I couldn't find it anywhere. Not in S.5 (where you'd expect), not in the appendices such as 4 (also...

    Not ground ginger, the real stuff! Just a couple of thin slices.

    ElectriciansForums.net Recipe and General Food Lovers Thread!

    Black tea, ginger, honey, lemon. I kid you not, half the singers you’ve ever seen will have downed that before taking to a stage. Must have made gallons of the stuff (not because it’s my job to, but because I’m nice).

    Singles in ducts

    The rules on parallel conductors are very clear: same length, same OCPD, same terminations. That’s why there’s no other derate factors applicable - doesn’t matter how many cables there are (we always assume two sets but no reason for three or more), it’s the same circuit.

    Singles in ducts

    Absolutely this. But only if the ducts are the same length!

    Hot glue

    [Genuine question] Is it more likely to be contaminates on/under the glue rather than the glue itself? It just seems so unlikely when I’m fairly sure if I go and IR a glue stick my meter will laugh at me.

    AC vs DC, live vs neutral

    Pop a post up in Electricians Jobs - https://www.electriciansforums.net/forums/electricians-jobs/ and I'm pretty sure there will be a few people in/around your area. @D Skelton might be able to assist. And no, MICC isn't an everyday wiring method anymore.

    UK Odd Electrical Fault in bathroom between taps and tiled wall

    I'm assuming that these have to be stone or another non ceramic tile?! I'm also assuming that you've verified water bonding and maybe gas as well if that's the source of DHW. You might also want to check all other exposed conductive items elsewhere to be sure it's not actually a back-fed earth...

    AC vs DC, live vs neutral

    So are you looking at buying this place? If so, then as part of your normal surveys just get a competent electrician to conduct an inspection and go from there. And no, MICC would not provide a 'giant earth rod' as whilst it would maybe introduce some additional parallel paths to earth (and...

    Possible New Idea For Forum?

    Totally! Top floor, end of corridor, non road side! In fairness, a proper big hotel doesn't make that much difference to road-side as the soundproofing is normally pretty good. There's a risk, though, in this in summer time that you end up in a room that's scalding hot and stuffy so keep your...
