3 Plate Loop-in Method for Wiring a Domestic Lighting Circuit - Connections Explained

Student training aid for the connections required to wire a lighting circuit using the 3 plate loop-in method. Video explains the connection required within the consumer unit (fuse box), ceiling rose and one way switch. The circuit is wired in 1.0mm2 twin and CPC cable (twin and earth cable) and fused at with a 6 amps type B circuit breaker.

The connections in the consumer unit (fuse box), ceiling rose or batten lamp holder and one way light switches explained when wiring using the 3 plate loop in method for wiring a lighting circuit

My instructor tried to explain this using drawings, this explained it much better

[rashadhassan]

You are an amazing instructor/ teacher. I've learned so much and completed some amazing jobs that would have cost me a fortune.
Thank you so much for sharing your video's.
Your students will be blessed to have you teach them.

Another well structured and well presented video. I’m not an electrician by trade but find these videos very useful for understanding the house wiring.

[lesclarke]

What a great video thank you really enjoyed it and fixes my lights

[robertpeters]

Thankyou very much so well explained and presented.

[jkw]

Wow. I'm currently studying my electrical at level 1 and this is really helpful as it gains my knowledge and understanding in this trade, really awesome video and well explained. Thank you 👍

[adalbertchiperco]

Very helpful, absolutely fantastic. Thank you very much for your efforts.

[bobkent]

Thanks for the video it may have answered my lighting problem, I have a light that has stopped working (bulb ok not tripping), but also the light in the hallway that are on the same circuit. I am guessing form your video that the rose could be the issue as the power is not then getting to the next rose in the circuit, so possible become loose.

8ve always preferred this method. Lately I'm doing more switch Terminated.

Thanks for posting video, quite helpful. I'm trying to pick up some electrical knowledge as I work in the building trade (carpentry, decorating, plastering) but its not easy. Whenever I read books they launch into protons, neutrons and electrons and doing the maths of working out resistance on a parallel circuit, all seems a long way from deciphering the spaghetti of a 2 way switch with 3 different colour codes and a new light fitting that requires an earth, if I'm honest it drives me up the bloody wall. Electricians don't seem to help as they seem to be a law unto themselves, I was recently working in a bathroom, removing a light fitting so I switched of the lighting circuit fuse only to have my screw driver explode on me because the light had been wired of the ring main. Admittedly I should have double checked if it were live but its a bit like having to look left and right when pulling out into a one way street, you don't expect some twat to be driving up it the wrong way. If I sound like I'm having a bit of a dig at electricians, I am, stick to the rules and please sweep up all your crap after working on site as you are notorious for leaving it behind for everybody else to sweep up, ditch the prima donna syndrome. Anyway, Ive gone off on a rant, appreciate the video, thanks

[sanoojkutteri]

Would you please explain how we put different switches for multiple lights please... way you explain excellent...in a same room like kitchen..

[craignsharon]

I love the videos but this one is very hard to understand due to it all being wired already.
It is hard to see where each wire is coming from.
Thanks for posting the videos I am learning and need simple videos with diagrams or actualy doing the job in front of us

[Eiquanshouldseethis]

What should I do if I need more light with independent switch? As there is 1 rose in the room fit with the light. There are 3 cables in the rose loop in loop out and switch and there is no empty terminal in the rose

[busman]

Have you ever heard of the term "Travelling switches" used in controlling lighting of long corridors (in hospitals) . I recall my tutor mentioning them, however that's a few years ago now. It involves progressive switching e.g. switch one turns on the first fluorescent light, switch two turns off the first fluorescent light and turns on the second and so and and so forth. I have forgotten how this arrangement would be wired and which switches would be used. Any ideas or do you have a video ?

[michaelwoodward]

Would also be good to show how led downlights are installed & how you fully test them ie R1+R2 & Insulation Resistance testing either at 250v dc or at 500v dc with Line & Neautral connected together.

[thevoidire]

What do you do if bedrooms number two needed 2 or 3 lights controlled from the same switch?

[davidkane]

My house is wired in this way. I'm looking to add a light on a switch in my loft. Do I need to get into a live cable to an existing switch, add a junction box and then run a new cable to the switch and from the switch to the ceiling rose?

[db-bvrs]

If using twin brown and not line and switched line, how would you know what brown you’re putting into the feed and the one to the com in the switch. As you could put the one of the browns into line feed in the ceiling rose and the same brown into l1 in the switch.

[mrdarn]

Somethimg I've always wanted to ask:
Since EVERYTHING (except the protective cable) behind a switch can become a switched line at some point, and every "competent person" understands this as a fact, why is the brown sleeving required at the switch end?
I understand why we identify it in the lamp assembly, but surely identification behind the switch is overkill? I cannot think of an occasion when all cables except the epc wouldn't become a switched line behind a switch.

Thanks!
