Gas Boiler Safe Isolation Tests / Checks - Day in the life of a Plumber

[@paulrossiter9567]

Quality video 👏👏👏 can’t believe some of the negative responses on here. From what I seen (I ain’t no electrician) that was perfect safety testing. Thankyou for jogging our memories and sharing 👍

[@AllenHart999]

Thanks 👍

[@gm2407]

a good video to know your plumber is doing it right and keeping everyone safe.

[@leerussellsmith8558]

Thanks Allen for this video, and all the others. Cheers mate, Lee.

Im more commercial than domestic and i have my head in panels everyday so I have C&G 1 and 2 in electrical. Don't you Domestic guy's have to comply to TB118? Informative video by the way for folks that don't know. 👍

[@AllenHart999]

Do you have any jobs for an old apprentice 😂😂😂

[@Ellielug1]

That was really clear and helpful - thank you

[@michaelnaughton9911]

Alan- in the live test, the instructor talks of the neutral to earth test with 15 v induction but summarises it as a neutral to live . That it I'm still half asleep .

[@markshaw1533]

Great video Allen, every day is a school day.

[@heatpump8566]

Great video Allen 👍

[@AllenHart999]

Thank you very much.

[@johnnybarbados8211]

Unfortunately, testing 3 phase circuits to ground doesn't end well, but it's fun. I'd love to see more commercial stuff in your remit, even if it's paid for. They're good videos. Maybe explain why Evomaxs' are prone to loud noises after 2 years 😬🤷🏻‍♂️

[@davidceredig-evans8772]

Excellent video. Many thanks.

[@baffoxxx2117]

Hello, I wanted to ask a question: In my boiler I hear a bubbling noise as if it is boiling inside the primary exchanger. Could you please help me understand the problem? Thank you

[@con6951]

Great video helpful for students like me. Thumbs up!

[@mgbroadsterJ]

I'm all for safety but will the customer be happy to pay more ?

[@AllenHart999]

Why would they pay more?

for any safe isolation you should be using an approved gs38 voltage indicator and proving unit or known source as well as locking off the supply be that using a fused spur lock off or locking off the circuit at the mcb, you can't just rely on removing the fuse as anyone can come along and throw a fuse in, also multimeters can't be used for isolation because of the chance of selecting the wrong measurement

[@seandempsey7351]

As for not using a multimeter for safe isolation because it is easy to set the wrong range. I have to disagree, why ? Because if you’re silly enough to set the wrong range on your multimeter then your silly enough to set the wrong function on your MFT , I have seen an electrician about to do a Ze test but he set his megger 1751 on continuity and wonder why there was a loud bang followed by a big puff of smoke and sparks from from his megger and now it is in need of a very expensive repair , at the end of the day it’s easily done , but I but he won’t make that mistake a second time.

[@stuartgammie1862]

Daft question but how do you know if you have reverse polarity? Is the reading different to what was in the video?

[@paulkelly3254]

I’ve got a full sheet telling you results and if you’ve got a different reading Stuart, phone was playing up so I didn’t get to that part👍🏻 I can send it you

[@cumberland1234]

If someone has swopped L&N somewhere on the supply you’ll get a reading of about zero volts between L&E, 240v between N&E.

[@SAS-gu9kl]

Good video boys

[@kelvinellis9155]

Shouldn't the tips on those probes be more insulated?

[@lizardboy0802]

Well done lad. Ya are completely right. Those probes don't comply with IEC 61557.

Allen I would like to assist with the multi meter video as I have got a few different meters that would be of some use

[@AllenHart999]

If you have any videos please feel free to send them on whatsapp Thanks.

Allen Hart could you email me [e-mail]

[@petersutton3054]

Socket and see are good for theses tests

[@ArksE8]

I dont know much about electricity. I just volt stick anything metal. If it bleeps I'll refer them to a sparky.

[@herrklamm1454]

Allen can you explain why we need a two pole voltage detector AND a multimeter?

[@jamesdyas542]

2 pole testers used for safe isolation should be GS38 compliant which a multimeter isn’t. A multimeter performs more functions than a 2 pole tester. That was what I was told last time I went on a course anyway. Hope this helps.

[@cumberland1234]

Put simply, a gs38 approved voltage indicator is the recommended tool for testing for dead. A multimeter isn’t recommended as it may be set incorrectly whereas an approved voltage indicator shouldn’t require any setting. Approved voltage indicators should be proven before and after each use, either on a known voltage similar to what you’re checking or on a proving unit. A multimeter is useful as a measuring device, i.e. for an accurate measurement of volts/amps/ohms etc.

[@jamesdyas542]

cumberland1234 agreed excellent explanation.

[@jasongeorge4602]

Great video as usual mate

[@salandjim]

Where in TB 118 is the as operative instructed to perform a 'safety toch test' or an earth loop impedance test or a polarity test - the ONLY 'procedure' derined in TB 118 is the Safe Isolation procedure ! This video does nothing more than add to the confusion within the industry because TB 118 is ill-conceived, misguided, misworded, inaccurate and contains an unforgivably dangerous bunch of words - it should be no more than 2 pages long and explain what is in the title of the TB - a SAFE ISOLATION PROCEDURE ! The objective is simple - prove the test gear good, isolate the appliance, prove the appliance is dead and then perform a confidence test of the equipment to prove it is still good. Th edocument has opened the flood gates for test gear manufacturers to sell kit for checks that are NOT required to keep the gas operative safe ....

Sorry to poo poo Alan but it’s all a bit flaky , can you link up with sparky ninja on this (FB) , they will help on a better step by step Guide , just trying to help ,
