How would you PAT test a “figure 8” IEC C7 cable?

thank goodness to hear someone who knows what they are doing. number of arguments I have had with our FM dept over the years that visual inspection was the only tests they could do on a 2 core plug for a laptop.

As someone who has just started up PAT testing and have just done my first 2 jobs I find your videos extremely beneficial and would like to say thanks. Yes you learn on the course but that is a classroom and not the real world. I will keep watching your vids . Thanks Ben

This was useful. Although I don't think you said so in the video, I checked what PAT testing machines do for the RISO test and they short live and neutral together and then apply the 500V (or 250V if you're operating at reduced voltage for a surge-protected appliance) between the live/neutral (now electrically one) and earth. I understand that's the standard, meaning all PAT testing machines work that way. I didn't previously know that, though it makes sense and also supports your conclusion. Similar logic applies to something I've been puzzling over, which is those shaver adapters that convert from standard 3-pin male to 2-pin female for shavers and some toothbrushes.

I've always visually checked the fig 8 cable but then used it to test whatever appliance its for as a class 2 so it checks both because you need to test the appliance. What's your thoughts 🤔

We have a few sewing machines using these figure 8's and a couple using the GST18's (all connected to a 'string' of power packs) in a cable tray.

I personally test it as class two by plugging the BS1363 plug into my tester and the other end into the fig of 8 adaptor (like what you have shown in the video) and then into the iec port and then select class two test, I was advised to test this way by the manufacturer of my machine, but to also put more emphasis on the FVI and log it in the Notes/Comments.

When I done my City & Guilds 2377 I was instructed to do a FVI and test a figure of eight lead (if on it's own) as class two and either leave the earth test lead off or clip it onto or near the end of the fig 8 lead.

I don't really see the point of this but I do test them now as I previously stated above, as I can not just enter a FVI on my test report without carrying out a test on the tester, (it's just the way the software works on my machine), I then just make any notes or comments in that section on the test report.

i do agree with you. Just visual inspection. very useful informative video. Thank you.

This is not a figure 8 cable, but only a figure 8 plug. The cable is double insulated. Figure 8 cable generally is not double insulated and hence might not fit the class of appliances of your country that can pass a PAT test.

[MrKwelsh]

An insulation Resistance test is checking that there is no short between the conductors. You could do an insulation resistance test between the line and neutral conductor.

[markellis]

c7 to c13 adaptor the do manual tests for. Or plug into an appliance and do class II test. Or use adaptor the manual tests. Also in my opinion if a person PAT testing pugs a class II lead into a C13 adapter the plugs that into Class I then he should not be doing electrical testing, in the field is not the practice ground that’s how to kill.

You can bridge the fig8 end and do a low ohms reistance test up and down both conductors, that will verify it's ability to carry the current rated on the fuse.

Hello what is the smaller version of that c7 cable called that can fit in small double holes

[michaeloconnor]

4:30 'An insulation resistance test is looking for any leakage to earth.' Is it?

[martynmasters]

Hi, Agree regards visual only check on the lead, but regards to the items it powers i, e cd players, sewing machines etc you still plug it into the item and run class 2 test to test the actual item as be making a circuit round using the item ?? or im i thinking wrong ? thank you

[GSF]

not saying your wrong, but if the insulation resistance is only measured against leakage to the earth wire, then what is the point of testing any class 2 item ? is the test current not put just down the live wire so it can be tested for leakage to the neutral wire also ?

[mohammedshalash]

You can check fuse rating, Live/ Neutral continuity ...
