Under BS7671, what is the amperage of 1.5mm2, 2.5mm2 and 4mm2 copper conductor restricted to when inside a race way or cable of no more than 3 current carry conductors? Thank you! :smiley2:

I note that it's ex GF.My ex GF had no objection to me calling her a septic.
Screwits or Wirenuts, whatever you want to call them were banned by our company during the 2[SUP]nd[/SUP] year of my apprenticeship. I’ll leave it to you to work how long ago that was.
My sweet Southern Belle would be quite offended, horrified even, to be called a Yank.
I'm not too sure i could put up listening to that slow Southern Drawl day in, day out for a lifetime!! lol!!
That's a bit offensive isn't it?. Daz
Whilst I agree with you and wouldn't use them myself (they just dont seem right to me for joining cables) there are a lot of "reputable" electrical suppliers out there flogging them quite happily and no-doubt "professional" electricians using them.
Got a big display of them at my local electrical supplier -- and not B&Q before Pete comments!!
She has the accent without the drawl.I'm not too sure i could put up listening to that slow Southern Drawl day in, day out for a lifetime!! lol!!
In regards to earth loop impedance, this is just to make sure the continuity of the earth conductor is UN-interrupted? My understanding is that the Active and Neutral is shorted to ground at the furthest socket on the circuit and a measurement is taken between the Active and Neutral across to the Earth conductor from that circuit? Active, Neutral and earth are all disconnected from respected terminals at the consumer unit during this test as well as making sure nothing is plugged in.
Guidance Note 3 explains our testing procedures.
Errr, i don't think they will have GN.3 readily available in the States!! lol!!
Pointless doing any ELI or live tests on a trailer at the factory anyway... They will only make sense when the trailer is hooked up to the power supply at the location it is to be used....
Don't think it makes interesting reading......for anyone.Well he has a PDF of BS7671 from the internet apparently. I don't expect that is readily available either, hence the PDF. I only mentioned it as it might be something he would be interested to read.
