    0.5mm T&E cable now available.

    I moved into a new developer house in 2001 - I am not there now. All houses were wired in 1.5mm lighting. Until LEDs became the norm, I have never come across any new build or rewire using 1.00mm lighting cable. Not one. I am not making this up. Your experience is 100% the opposite of mine.

    0.5mm T&E cable now available.

    You are giving an opinion. The fact is that rule of thumb was the normal for domestic lighting cable sizing in using 1.5mm. Few ventured away from that size. Most of the time lighting cable was vastly oversized.

    0.5mm T&E cable now available.

    When it came to lighting in domestic houses rule of thumb was paramount - 1.5mm was used with few even thinking of using anything else.

    0.5mm T&E cable now available.

    I had neevr seen it installed or for open over the counter sale until around 10 years ago. That does not mean it was not there.

    It can be for sure. An added safety level. Have a 3A mcb and a few 5A round pin lighting sockets and plugs, supplying table lamps with 0.5mm flex plugged into the 5A sockets, then the 3A mcb covers it all.

    0.5mm T&E cable now available.

    It may have been available on order, but it was not sold in the mainstream dealers for sure. I was not aware of it. I came across it as a general stock item about 10-12 years ago when LEDs took off like a rocket. I recall about 7 years ago a developer fitting 1.00mm T&E on the two lighting...

    0.5mm T&E cable now available.

    My point was that when 1.00 T&E was not available, many would be saying you can't introduce that bootlace when it was mooted 1.00mm T&E maybe coming. I think I saw online a 2A//3A RCBO. Not cheap. Yes, 6A lighting MCBs and RCBOs are too high a value these days.

    0.5mm T&E cable now available.

    Entirely up to you. Nothing says you cannot. Before 1.00 mm T&E I am sure many viewed having that as they are doing now with 0.5mm. What! Such skinny cable! Although when using 1.00mm cable fitting a 2A MCB must tighten up the safety margin. If you have a light switch switching a 5A round pin...

    0.5mm T&E cable now available.

    But the conductors are thinner when working inside backboxes and no earth sleeve needed. The flexible CPC conductor is ideal for connecting to metal backbox terminals. Pulling either of them will be similar. Then 0.5mm is cheaper. An April Fool's joke sparked some positive thought. :)

    0.5mm T&E cable now available.

    One point raised. I prefer having a lighting junction in the light switch backbox rather than at the ceiling rose. It is easier to fit and fault find. Using T&E and a Wago in the light switch backbox made matters tight in there. 0.5mm and Wago in the backbox, makes it all so much easier. Just...

    0.5mm T&E cable now available.

    CH control wiring on retros is done using flex. A two bedroomed flat with a 2A RCBO or MCB using 0.5mm, as been mentioned, can do the lighting for sure. 0.5mm has a maximum current load of about 3A. If there was 50 5w LED lights in the flat, it would be highly unlikely we know, it would be...

    0.5mm T&E cable now available.

    They did a good job. Where did they get the 0.5mm T&E? It was obviously thinner than the 1.00mm cable. The points is, is that 0.5mm and a 2A MCB or RCBO (which are available) would be perfectly safe using 0.5mm cable. The max current draw of 0.5mm is approx 3A. 50 LEDs consumes 150 watts. So...

    0.5mm T&E cable now available.

    I just did a search and 2A RCBOs are available as well. Sometimes there is the seed of a good idea in a joke.

    0.5mm T&E cable now available.

    He only did the lighting circuit. It worked well and a neat job as well. I only saw the CU. It worked and was safe. He did his homework on safety, the max amps loading of the cable, etc. No way would the cable overload using LEDs and 2A MCB. I never saw any bodged DIY work in the house.

    0.5mm T&E cable now available.

    This reminds of a few years when I saw a lighting circuit in a one bedroom flat wired with 0.5mm flex, as all lights were LED. The guy got a reel super cheap or for nothing. He used a 2A MCB. A neat job. He said to wire up lighting switch backboxes it was super easy as only thin wires, and that...

    0.5mm T&E cable now available.

    What about their E. And 0.5mm taking 8 amps max current. :) 0.5mm cable takes a max current of 3A. Having 50 5W LEDs in house is 250 watts. That is around 1 amp. So 0.5mm will do a very big house. So not that much of a joke. :)

    New 0.5mm T&E cable and 2A mcb's avialble, as lighting loads are now so low because of LEDs

    Main MCBs replacing incommer switches

    A main incommer MCB need only be for overload protection not fault. A string of RCBOs can cope with other issues.

    Main MCBs replacing incommer switches

    Oh! Now I know. What is the standard size of main fuse there? 60A? Many 100A?
