"Why Are There Two Lives From Separate Circuits At A Light Switch!!!???" | Electrical Fault Finding

[@JayTheSparky]

New build and they’ve fed something from a spur off the ring? Kept it on the same RCD as the lights so no neutral tripping issues

Good video.Seen it where they put a double pole switch in so one side does lights the other a heater or maybe a fan as an example.

[@JayLovesProgramming]

Very true! Delroy, could it be for a fan maybe? Would this actually work?

[@JayLovesProgramming]

Yes cracked it! kzbin.info/www/bejne/h6WampmZiM9-jck watch that video guys and Delroy. The end bit explains how they can be two lives at a switch. Why they're from 2 different circuits no clue but good video delroy mate

[@monikaw1179]

@@JayLovesProgramming This is NOT the standard way of wiring a fan and light to come on together. I've installed hundreds of them and never used a double pole switch.

[@JayLovesProgramming]

@@monikaw1179 oh no definitely not. Much better ways to go about it

[@oldbutstillcurious3615]

@@monikaw1179 ? In simple terms, what do you recommend to avoid taking two supplies, each from a different breaker, to a single switching module ?

[@ryanatkins3013]

I thought it may be todo with the heater in the bath room for the extra switch possibly good vid tho 👌

[@johnandrews4144]

Love the way you say hopefully you picked something up from that,!! Hopefully after reading the comments you have lol, but dont despair we all live and learn you'll know from now on and that's what matters, be a boring world if we all knew everything

[@andrewlougher-harris5492]

the cables should have been labeled in the switch too inform the next spark

[@lewistempleman9752]

Nice one delroy you're an inspiration

[@k1lmo]

I bet the heater in the bathroom isn’t working how you left it

[@jamiebaker5690]

I was thinking the same, something is now disconnected, its ok, another callout charge when they realise something isn't working haha

[@heronimousbrapson863]

I can hear a North American electrician asking: What the heck is a ring circuit?

[@David-dz8jb]

Seen and installed dp switches to be used where internal bathrooms/toilets share the same ventilation fan so it avoids commoning the sw live to all the lights. Not seen it spurred from the ring but maybe there is a heavy duty fan motor and that requires this.

[@danf6491]

Presume that wire was linked to the extractor or fan heater. Controlled by a double pole switch. Would have been better if they fitted a 2 gang or at least identified the cables. Also I'm sure you meter beeps so some croc clips to stop ya walking back to the fuse board might help. Did the client ever call you back?

Still live because of the fun booster!! You need turn of fun booster too :)

[@dans5101]

Thanks for sharing Del mate

[@lammy2304]

Can’t believe I’ve spent another 5 minutes watching you back and forth to the consumer unit for a second time !! Buy a beeping volt stick !! 🙈🙈

[@benh1216]

When you mean volt stick I presume you mean voltage pen? Also correct me if I am wrong since I am no electrician but I heard you can't use a voltage pen to prove dead on a circuit? Since I presume that's what you mean in regards to checking the CU.

[@lammy2304]

@@benh1216 yeah one of them ..... he wouldn’t be using it to prove dead - he’d be listening for the beeping to stop whilst stood at the consumer unit switching off relevant mcb’s to identify the circuit it’s fed from. Then he could prove dead if required. More for identification than proving, one of the best uses of the volt stick/non contact voltage indicators. Saves walking back and forth after turning one mcb off at a time.

[@benh1216]

@@lammy2304 ahh makes sense. Also yes I do that too. Don't know why I thought he would he using it to prove dead 😂 doh. Very useful piece of kit however. Definitely useful to give you an idea if a circuit is dead or live!

[@neilvincent9530]

I always thought you could a lighting curcuit on a ring final curcuit

[@mathman0101]

Nice one Del.

[@neilvincent9530]

You can take a lighting from a ring cuurcuit As a electrician I thought you would of known that

[@andrewkelsey7777]

umbrellas on the CU 🤦‍♂️

It's a domestic what do you expect? That is totally normal lol

[@normanboyes4983]

Delroy - I reckon you walked six miles there.😉

[@jujulimbu4443]

Hello sir,Can i work with you, I'm nepali

[@neilvincent9530]

How come the tenant seem to know about it very strange

[@Electric-First]

I had an issue few weeks ago, tenant was complaining about rccb keeps tripping. I carried out IR LN-E and all good >999 M . This happening immediately when tenant switching on washing machine from FCU . I advised tenant change washing machine or call engineer to check it . Tenant has changed washing and it continued tripping rccb. Then i start thinking may be because of dish’s washing machine also connected to the same circuit and may it has small residual current leakage. So , I connected ring circuit to 32 mA rcbo type C and it’s stopped tripping. The problem was caused by small residual current and by Crabtree rccb which was too sensible.

[@normanboyes4983]

Sensible Crabtree breakers are to be recommended.😉

[@davids5498]

Didn’t even put the downlights back up for the guy? Wtf.

[@Muskoka62]

You need an apprentice save all the walking

[@colinbradders9166]

Normally i have found with domestic stuff you have to think like the idiot before you more than actual genuine electrics 😅.
