JCC V50 all the way 👍

I'll be honest I'm not sure where myself or the client stood inspecting fuses that contained asbestos flashguards behind? (I have to return anyhow so can check) Do you agree that a code 2 would still be present for the user exposed to live conductors upon replacing fuse wires? (Forget damage to...

If I'd have just posted photos, you'd have asked for my opinion. I do have a degree of competency (according to certain governing bodies and various firms) and am extremely passionate about my job, however I'm not having the best time at the moment, hence swallowing my pride and posting some...

Wow. What a helpful forum. 👍 Appears nothing but a 'hieracy' that inisist on condescending comments. I've got one man telling to me conduct a Ra when totally unnecessary and didn't even realise you could use the building structure as an earth. .....and another insisting on a single code that...

I haven’t see a sparky carry out an Ra test on a TT for a very long time, a few times if that. I haven’t got my regs book to hand but perfectly acceptable. I will forward tomorrow. Carried out install on farms before, bonding a great piece of conductive steel and knocking an earth rod in beside...

…..but yet again the user is exposed to live conductors before even accessing the fuses. Did you know the DNO use silicone to reinstate IP ratings on Henley blocks? Clearly not competent to carry out said works either! ……Its not me isolating a circuit I’m worried about. I understand you would...

Why would I comment on that if the users already exposed to live parts upon opening the cover to replace a fuse?? Its not the fault condition I was referring to...it was a single device not isolating all line conductors for maintenance on circuit etc. (yes I know the main switch will suffice...

I have disconnected the earth and carried out a Ze. There is no requirement to carry out a Ra just because it’s a TT system. The test can be carried out as normal practice in a TN system. Your not getting my point. It’s perfectly acceptable to use the building structure as the earth. I have a...

The rod is on the opposite side of the steel. No I haven’t done a Ra because I’ve used test method 2 with the loop tester. The structural steel will be acting as the earth compared to a earth rod.

Me neither, but all 3 fuses are operated by a isolator before opening the cover.

Carrying out an EICR on a farm and just after some advice regarding my codes. This is only the supply to the barns. House has a separate supply. TT arrangement with an electrode, although tbh the steelwork will be acting as the earth. 100mA upfront and 30mA protecting relevant circuits. All Zs...

Yes Murdoch. I'm aware of the need to earth the armour. Just intrigued regarding fly leads when the cpc is integral to the cable as was pulled up on this. Despite all SWA entering galv trunking. My argument as stated above is why any different to conduit?? I'm just going to attach a protective...

Do you say that for guidance notes and 7671??

Thats why the armour is connected to earth, albeit through a joint in the same way as conduit and MICC. There's alot of reputable names and organisations behind codebreakers.

Hi all, first post... Does a SWA cable incorporating an integral cpc require a protective conductor between the armouring and the earth terminal of metallic enclosure? I got snagged on this during an NICEIC assessment. I tried to argue the point of conduits and MICC cables relying on joints...

Providing your Zs is acceptable a 1.5mm cpc is perfectly fine on a 32A OCPD. Just to note a 4mm PVC/PVC contains a 1.5mm cpc, a 6mm contains a 2.5mm.
