It's not just for insulation testing though, it's also so you can confirm ring continuity, or in the case of a radial, continuity to the end point. You don't have to check this shit, but you're fucked on second fix if something's wrong even if you suspect it's down to another trade having damaged your cabling. If you can't prove it was all good when you left site after first-fix, then the client's just going to assume you fucked up, and if you have to chase out newly plastered walls or pull up newly laid floors to fix it, then the expense for that may be expected to come out of your pocket. It's a risk assessment: do you skip the testing and hope it's all okay on second fix, or do you undertake the testing to cover your arse against things going to cock at second fix? I take the safer option because I've been on site where builders have damaged my cables in the past.

RAD Official that supply voltage is a little lower than I would expect, I wonder what the voltage is at the main house supply. Normally the earth current is very low, some appliances with mains filters will pass a little earth current but very little. It might be worth extending one of the multimeter leads so you can measure the voltage between the incoming earth and the earth in the extension. There should be next to nothing between the two points. There are various different ways that the supply earth can get to a property if your “earth” is a TT type (ie a grounding stake) it would appear to have a significant problem. Personally I would investigate that prior to adding more.

Hi David. New to the industry so really appreciate the educational video. I'll be sure to watch all of your videos now. Can I just clarify my understanding please? So, if low IR between L&N, that means something is connected, but L/N&E should still give a high reading in that case. A low reading between L&N, but also low IR between L/N&E would indicate a fault. Is my thinking correct?
@dsesuk
4 жыл бұрын
Hi Nina, thanks for tuning in! A low reading between L&N *may* indicate a connected load; certainly that's more common than a fault condition. It's something that warrants further investigation if you want a number out of L/N. Connected loads shouldn't provide a path to earth though, at least not unless there's something providing an additional service between line/earth such as a surge protector. I'm speaking of domestic equipment of course; commercial or industrial equipment may have goodness knows what to confound things! A low reading between L/N&E, especially at 250V so SPD's aren't triggered, needs investigation. Something's causing it, and it can potentially cause trouble!

Thanks for your reply, David. Yep, it’s a domestic socket circuit. Definitely no surge protection and all accessories have been removed (as far as I can tell). L-N is reading 0.25M at 250V and L/N - E is reading 0.5M at 250V. Obviously, I didn’t test at 500V after such ominous readings!

@@ninav74 Not great numbers those. I'd start braking down the circuit next. If it's a ring, then split it at a socket which ought to be around the mid-point and test each leg, then keep braking it down as best as possible until you find where it's bad. Of course, it may be difficult in a furnished house. We had one last year which we traced to a socket some idiot had spurred off and hidden under a floor where the neutral wire was leaking to the earthed knockout box through a split in the insulation. We only found it because they were remodelling the house; had the new carpet gone down we'd have been scuppered.

Hi Tony. Nice to see you back. My apologies for my previous rude comments, you caught me on a bad day! To answer your question, no I'm not NERS certified and I don't know anyone who is personally. It's for people who work on the network, or at least that's my understanding, so it's for those who would be working on utility equipment rather than bods like myself who only work on consumer kit.

Can you then test the board as a whole using the Line/neutral & earth without risk of damaging any sensitive equipment at 500v
@dsesuk
5 жыл бұрын
Hi Lee. If the neutral bar is connected to an RCD, then you may have to disconnect it to save shoving 500V into it. You could then disconnect all the line wires and common them together to perform the test. It's not ideal though as the result you'll get will be lower than the lowest individual circuit resistance because of Ohms law regarding resistances in parallel. As an example, if circuit 1 is >999MOhm, circuit 2 is 300MOhm and circuit 3 is 6MOhm, the number your tester will measure will be 5.8MOhm. It tells you something about the installation as a whole, but not the health of the individual circuits. This is shown in more detail on my video about insulation resistance and RCD's if it helps!

Thanks David. If you perform the test as you describe it and your result is greater than 999 then does that then confirm that the whole installation is sound or could there still be issues on another circuit
@dsesuk

If you've commoned all the lines, joined them to the neutrals at the neutral bar and then tested to earth with a resultant reading off-scale on your tester, then that should indicate the installation as a whole is good and you don't need to test individual circuits. Oh, one other thing, the neutral bar would have to be disconnected (whether on an RCD or not) as neutral is connected to earth back at the intake (if PME) or at the transformer (if TNS) and would cause the test to fail if that connection remains!

Yes, you can... Carry out safe isolation on the main switch, if it's a dual RCD board, switch off the RCD's but keep the MCB's in the 'on' positon. Using a piggyback lead, connect croc clips to neutral bar 1 and line busbar 1, then connect remaining lead to earth terminal and zap... all clear, then test between neutral bar 1 and line busbar 1 and zap... all clear, then repeat all of the above on neutral bar 2 and line busbar 2.

On my testing course they told us if you short live and neutral at the board you don't need to worry about unplugging anything????
@dsesuk
5 жыл бұрын
You can short line and neutral at the board (i.e. busbar to neutral bar with breakers in the ON position) to test the whole installation at once with respect to earth, but there are three things to note: 1. Make damn sure the installation is isolated and that the short is removed before anything goes live again (I really don't like the idea of this as it introduces the potential for a major fiery fuck-up). 2. The neutral bar would have to be disconnected, otherwise it's already connected to earth in a TN arrangement so the test would fail (again, I don't like this as some idiot may re-energise the installation after forgetting to reconnect the neutral bar making all appliances appear dead when they're actually live). 3. The resultant measurement would be lower than the lowest individual circuit measurement because of Ohms Law for resistances in parallel. This means your tester might give a reading of, say, 0.5MOhm simply because one or more of those circuits isn't optimal on its IR. That number only indicates something isn't 100%, it doesn't indicate which circuit(s) need further investigation. In short, it's a bad idea as whatever time it saves isn't worth the potential dangers being introduced, and the number you get out of it isn't particularly helpful. More on this can be found in my April video on IR and RCD's.
@darrenrcps7219
5 жыл бұрын
Yes they told us do the IR for the whole installation and then if the result is suspect you would then have to go to each circuit one by one to find your problem ....... I suppose it's the same thing as you doing live and neutral to earth for each circuit individually and not having to worry about unplugging etc if you missed something
@dsesuk
5 жыл бұрын
Personally, I wouldn't bother testing all circuits simultaneously on a periodic inspection, as it's pretty much guaranteed that one or more circuits will give a less than optimal reading, so for the effort of disconnecting the neutral bar and commoning up the lines and neutrals and the risk of making a cock-up when re-energising, you may as well just get on with testing the individual circuits anyway!

David Savery Electrical Services Hi David great video. Your reply above wrt testing the whole installation at the board, with the main switch (DP) off, all circuit breakers/fuses on, why would you need to “disconnect the neutral bar” on a TN (S or CS) system ? There should be no path between neutral (or line) and earth on any and all final circuits ? (not withstanding there may be under fault or degradation circumstances)

There's no point IR testing anything L-N if any loads on the circuit are connected, this includes LED or neon indicators in switches. You'd have to remove and wire out the switches to get a reading for the wiring itself, and it's probably not worth the effort unless you're tracing an overload fault. You can still test L-N together with respect to earth as switches with indicators shouldn't be leaking anything to earth.

That depends. If someone actually provided a neutral at the switch and the indicator is connected between L&N, it will show as a fault if testing between L&N, just like any other load does. If it's one of the old style ones wired between L & SL and only lights when the switch is off, it won't make any difference to the test. Such things are uncommon now as they only work properly with incandescent lamps. If some buffoon connected an indicator between L & E because no neutral was available, then it will show as a fault, and must be removed.

Hi Garry. For a basic PAT tester, the Martindale model I have is just fine. It does support 250 or 500V testing, but the only time the 250 option is needed for most homes, offices or shops is when I'm testing a surge protected extension board such as that shown in the video as that will fail a 500V test by design. The 500V test *shouldn't* trouble the computers as they should be designed to withstand it. I've never seen a computer damaged by the PAT process, not that I'm saying it can't or won't happen, but it's not happened to me and I don't take any special precautions for IT gear unless there's a manufacturer label on it clearly stating otherwise!
@650GSF

one of the IT guys at the school also does PAT testing, and his tester does have the 250v option, but he said he hardly ever uses it as the tester by default keeps going back to 500v every times it turns itself off, he then has to go through a sequence to put it back on 250v, so he just keeps doing 500v test, he also said that he has not damaged any of the hundreds of computers he has tested. Thanks for the reply.
