GS38 Test Leads and Probes the Requirements for Electrical Test Equipment for use on Low Voltage

[@artisanelectrics]

As soon as you leave college you never hear about GS38 again! 😂 Apart from maybe the annual NICEIC inspection.

Artisan Electrics Jordan will you be visiting Gaz at Tresham college this academic year?

[@artisanelectrics]

efixx I would love to! Just let me know when!

[@efixx]

Artisan Electrics of course you’d have to try the #ApprenticeWall challenge!

[@artisanelectrics]

efixx bring it on!

Here in Germany almost every electrician hangs the tester arround his neck, and some are calling it "electricians stethoscope". That's the best way, especially if your working on a ladder. Here the regulations say that you'll have to test the voltage tester on a known working source, it doesn't matter if it's a circuit or such a test device for voltage testers. Before and after, so same sandwich here. Sometimes the test devices got the disadvantage that you can't test the load connection if your voltage tester has this functionality. The shown Megger voltage tester unfortunately doesn't have that functionality of a load connection, but many others have it. And some of the test devices can't provide enough current to test it. I got several of those testers, from the simple neon indicator in one handle and a plunger coil in the other handle (plunger coil instrument is used as a load by pushing a button) from the 1950s up to a voltage tester as shown here and an industrial grade fully rubberized Tietzsch Prüfball (test ball) CAT. IV up to 1000V (most other testers are CAT IV 600V and CAT. III 1000V) and it is rated IP65. I suppose the regulations are the same as in the UK, here the voltage testers must be at least rated IPx4 because humidity has an impact on the insulation of the tester, reducing its effectiveness.

Wow what a detailed message and the for sharing it will us electricians in the U.K. 👍. Gaz

[@heyderaliyev8976]

great informative for those who are new to isolation process

[@ashmanelectricalservices4318]

A lot of modern voltage indicators have a self test function where all the LED's light to prove device is in good working order.

[@piney6587]

One main thing with those testers to look out for is that when the batteries are removed from the tester, the voltage indicators still work. So if your batteries run out for the other functions of the tester it still detects voltage

[@muzikman2008]

Like my fluke T150 it does a self test.. Then test on a 230V incomer, eliminates the need for proving units 😉

[@ashmanelectricalservices4318]

@@muzikman2008 It's more convenient when working remotely from the consumer unit to have a proving unit with you, otherwise you'd have to re-check your indicator at the incoming.

[@ashmanelectricalservices4318]

@@muzikman2008 The proving unit also has a light which illuminates when probes are inserted, this proves the proving unit is in good working order.

. I work in the railway industry as a maintenance engineer. I tend to quick for voltage first then trip a CB then make sure it is dead alot of the time the CB is at a distance from we're I'm working. Just because you think you have tried the correct CB doesn't mean you have. And sometimes not everything has a feed going to it all the time.

“Potentially touch those tips” 😆 I admit, I childishly laughed

[@georgedumitrescu9473]

Hi Gary. I know you said you have several other videos coming soon. Do you have one to show how to lock/ safe isolate MCBs RCBOs etc using the different locking systems available on the market. Thank you.

[@GSHElectrical]

A video like your request will appear on my other KZbin channel eFIXX in the coming weeks. Thanks for watching and commenting. Gaz

[@georgedumitrescu9473]

Excellent. I am looking forward to seeing your new videos. Well done Gary!

[@samlockley835]

do regulations, standards and rules change with different countries and where are you guys teaching from

[@williammcintosh6006]

Great video team.

[@AhmedMohammadali-pn3ud]

What is your recommendation for brand approved voltage indicators for demostic ? Thanks

[@watsond83]

Good Video Gaz, thanks :-)

[@nixxonnor]

Is my good old Fluke 87V with Fluke TP175 TwistGuard Test Probes* ok, according to the GS38 code? (* Exposed probe tip length 19 mm to 4 mm (0.75 inch to 0.16 inch))

[@Lukefreemann]

Find You a woman who looks at you the way these two look at each other 😂 ( your videos help so much btw )

[@nickrundall]

Gaz, you remind me of Alexie Sayle.

[@GSHElectrical]

Love it 🦾

[@DjChrisWilliams1]

Question.. What does GS stand for?

[@georgedumitrescu9473]

Gary’s Standards .. 😉

[@Dog-whisperer7494]

Good sound advice, but and this is a big but , Gaz you contradicted joe almost from the of , joe said the tips of the probes should have cover’s so they have a minimum of 2mm and a maximum of 4mm of exposed tips because when you touch onto a live part there’s a chance? If you’re stupid you could touch the other tip on to metallic casing and that’s not good as both tips will be live, you then said that there are set testing sequences witch you demonstrate on a number of other videos, is onto the least dangerous connection first ie onto CPD onto line of line of CPC onto neutral onto line of line of neutral, point two we all know that sometimes we have to remove the probe tip cover’s because the probe won’t reach deep enough to make contact so straight away we no longer conform to GS38 you have done this yourself the video we’re you demonstrate insulation resistance line and neutral combined you use a test probe with the cover removed and an R2 link between that and the neutral bar ,A gain GS38 sunk . As an extra bit of a rant it says we can’t use a multimeter for safe isolation? Because it’s to easy to set the wrong range ? Well what to stop you from setting the wrong function on your MFT ? If you are distracted or not concentrating it’s easily done. So GS38 is a nonsense just like we are not supposed to work on live circuits but sometimes we have to ie to do ZS and Ze tests and voltage tests . Rant over . Someone prove me wrong Great video and very informative as always guy’s 👍👍❤️

[@cag9284]

Make sure your proving unit battery is good.. 😂lol

[@GSHElectrical]

Thanks for the very positive comments 👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👍🏻👍🏻👍🏻👍🏻

[@cag9284]

It happens... Just saying.. proving unit are as good as only the batteries in them... Wasn't being sarcastic 🤷🏻
