WHY Does my Voltage Indicator Beep During Safe Isolation

[@bradleypyewell8986]

Been in the game 10years and always wondered why this was happening. What a absolutely brilliant video!! 😁

[@GSHElectrical]

Glad you enjoyed it! Thanks for commenting 👍🏻. Gaz

[@montystelevision3238]

I think this is the most detailed explanation of lighting continuity tests I’ve ever experienced.

[@GSHElectrical]

Wow unbelievable thanks for the great support Monty 👍🏻. Enjoy what’s left of 2022 and all the best for 2023. 🍾🥂 Gaz

[@Dog-whisperer7494]

I have to say that was something that confused me all the time till about four years ago. Thank you for a cracking example of excellent teaching and clearly explained.
Fantastic video as always Gaz 👍👍

[@GSHElectrical]

🙌🏻

[@StillLivingInChaos]

Well, who knew this would be so interesting! So obvious when you show it like this, but that was really well explained!

[@GSHElectrical]

Massive thanks for watching and the great comment 👍🏻

[@davidroche6973]

Great video and explanation, very helpful for people testing outside of the college environment who worry when first come in contact with these beeps when they were not expecting a beep

[@GSHElectrical]

Thanks MATE 👍🏻

[@mohammedezaj1018]

GSH Electrical, You did it very simple by explaining it on the practical way. Always loved your videos. Love from India. Great job Bro 👍 keep it up.

[@darrenqualters2341]

What a 1st class explanation there Gaz 👍 Yet another cracking video, well done

[@GSHElectrical]

Massive thanks I did enjoy making this one 👍🏻

[@TheEulerID]

You should also get neutral-CPC continuity on a TT system, albeit with a much higher impedance as the completion of the circuit is via the ground. The only supply system where that ought not to be the case is an IT one, and that's not something you will find in a domestic property in the UK (Norway is the only country where that might happen as far as I know).

[@rizgar8121]

Very good video Gary thanks for that.

[@alancooper7018]

Nice explanation. Might be useful to do a video on phantom voltages!

[@dmlelectrics8990]

Also a video on floating neutral faults would be good.

[@PHealey1981]

Lovely Artex Gaz…great video for learners, superbly delivered. 👏🏻👏🏻👏🏻👏🏻

[@GSHElectrical]

Thanks Paul as always for the support 👍🏻

[@tombickerton4114]

Excellent explanation and loved the diagrams .

[@GSHElectrical]

Thanks Tom for taking the time to comment and watch 👍🏻

[@SqwarkParrotSpittingFeathers]

Excellent as always.

[@GSHElectrical]

Thanks for the great support

[@bodybuilderatwork]

Excellent video as always. I have a request if I may, would you consider making a video on derating cable within insulations covering the various cable clipping/mounting methods i.e. in conduit within the thermal insulation etc. I'm sure with the way things are now with acoustic and thermal insulation going in walls/floors/ceilings galore I wouldn't be the only one to find it handy and also interesting to hear your thoughts on the best methods. Thank you!

[@GSHElectrical]

Great comment 👍🏻

[@sergiofernandez3725]

Great explanation

Thanks 👍🏻

[@kipdennis3796]

Thanks GSH always best at it!

Thanks for watching and commenting 👍🏻

[@itechprofessional1631]

Excellent perfect explanation in details ❤❤❤

[@GSHElectrical]

Thanks 👍🏻

[@Ben-zn8pe]

Great explanation 👍

[@GSHElectrical]

Massive thanks 👍🏻

[@IAmThe_RA]

What is the size of the wires linking the main switch to the 80A RCDs? And what is the size of the wires that go into the main switch?

[@rizgar8121]

Thanks

[@JustVisiting_]

Man, there's a lot of words that I don't understand. This is going to be more difficult than I thought.

[@GSHElectrical]

Sorry

[@JustVisiting_]

@GSHElectrical ha, not your fault.

[@faithful5475]

How about if you get 24v in lighting circuit between switch wire and natural

[@nocode1603]

Thanks gaz all is clear now 👏👍

[@GSHElectrical]

Thanks for watching 👍🏻

[@Dog-whisperer7494]

Maybe you could do a video explaining why the positive probe gives a beep when touching the face plate screws . I have noticed this on three of the switches in my house all the other switches are fine.

[@giorgos424]

Thank you sir!!!
It should be obvious but it was actually not, ..until I saw this!! :)

[@GSHElectrical]

Thanks for watching 👍🏻

[@bendavies8140]

Excellent video. Only thing if like was a shout out for us peasants out in the sticks living in TT system houses!

[@GSHElectrical]

Thanks for watching and commenting

[@mundent]

I have two questions. When you get the continuity between the switch live and N/E, would you lose the connection just by turning off the switch.
Second question, if the neutral is always connected to earth at some point then why doesn’t the RCD trip.

[@mikeenglish6734]

You would lose the connection if you turned off the the DP switch feeding the Dis board. No neutral path = no earth path. RCDs monitor the ingoing and outgoing current, if the path of electricity is altered, for example through a person the device will trip, equally if it flows through lets say the outer cover of a boiler (metallic) it will trip the device as the new path of current flow will be different to that of normal safe operation

[@mundent]

@@mikeenglish6734 That’s the part I struggle with. If the current is already connected to earth via the neutral what changes when there’s a neutral earth fault through the boiler casing like you say. The current still flows from neutral to earth.

[@brianhewitt8618]

Excellent👌

[@GSHElectrical]

Thanks Brian 👍🏻

[@bobsmith3291]

It’s because you’ve got the light bulb still in and it’s connecting the live and neutral

[@eddie_pegasus_electrical]

As always well explained, great video for learners to understand why this happens.
👊😎👍💙🦾

[@GSHElectrical]

Thanks mate

[@Bari_Khan_CEng_CMarEng]

Great explanation
