    Conductor insulation breakdown

    We’re already on the case, they’ve used this company loads in the past, so hopefully it’ll get resolved quickly. thanks again for everyone’s input :)

    Conductor insulation breakdown

    they look dry, the back of the plug is sealed with resin and the front of the plug pictured is dry with no signs of water ingress, some other light fittings on other circuits we have seen water ingress and it’s fairly visible, I was getting voltage transfer across all cores, even the Dali side...

    Conductor insulation breakdown

    Well, fancy a twist? the cable is fine, well technically most of it is, it turns out the fly leads that came with the lights are breaking down. They don’t look damaged in any way or any signs of water ingress, just a poor quality cable.

    Thanks guys I’ll continue my with my diagnosing and most likely get to the conclusion I assumed which is the cable needs replacing.

    Conductor insulation breakdown

    just to clear it up, to get to the ends of each cable I have to dig them out the sleeve that’s filled with sand and cement, but as my reply earlier I think I will do the first one, to be honest, if it is the cable I’ll have to dig them all out anyway to get to the cable duct at the bottom...

    Conductor insulation breakdown

    So back to the question, are you in agreeing that the issue is the cable is broken down and leaking current to earth? I agree it shouldn’t be buried.

    Conductor insulation breakdown

    They are IP rated JB’s I have access if I dig them out, I’ve currently got the middle light dug out with JB accessible. would it account for the rise in earth leakage as fittings are applied though, I was seeing and increase of ~4mA per fitting when fitted to the circuit, circuit will hold with...

    Thanks so far guys, the supply is 3ph but the circuit is 1ph. it’s a Schneider acti9 DB so individual 30mA 10A type C RCBO’s for each lighting circuit, which has been ramp tested to 28mA lighting circuit of which there is 4 problematic ones are all oblong wall wash up-lighters sunk into the...

    Conductor insulation breakdown

    I’m currently problem solving a lighting circuit issue on a retail park. newish install (12months old) IR of 12M Ohms across all three conductors, getting some very odd IR readings overall, I got a low reading between two separate disconnected cables, sent my meter off to be calibrated and came...

    Installation regs on multiple earth rods.

    I’ve seen the tool on eBay already thanks, I was going to take a grinder to an sds max bit and make my own :tearsofjoy: the rods came with a large Allen head bolt which I presume to be for the installation so I’ll just make something that fits into that :thumbsup: The ground is really bad where...

    Installation regs on multiple earth rods.

    That’s brilliant thanks, yea was going to use 2 rods but 2.4 apart, so I’ll just stretch it to more like 3m instead :)

    Installation regs on multiple earth rods.

    Better to ask than just plow ahead and do :) Like I said I’ve never really had to deal with installing Earth rods so I’m learning as I go. Common sense does point towards it not being an issue but I thought I’d just ask :) Thanks though.

    Installation regs on multiple earth rods.

    Hi everyone, just a quick question, Earth rods aren’t my strongest subject and I have no access to my 7671 at the mo, what’s the regs or guidance for installing multiple Earth rods? Issue I’ve had was services in the way, can the Earth rods be put into a different pattern than a square or a...
