Discuss 0.5mm T&E cable now available. in the Lighting Forum area at ElectriciansForums.net
When moved into a new council house in 1977 that was wired in T&E , wylex metal clad 8way with BS3871 mcb's.Certainly seen 1mm T&E in 80s installation.
The MCB is not there to protect the plug or the socket.Theoretically the 5A plug/socket is not protected using a 6A MCB
It can be for sure. An added safety level.The MCB is not there to protect the plug or the socket.

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.
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.Certainly seen 1mm T&E in 80s installation.

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.Rule of thumb means absolutely nothing as there are many thumbs with alleged rules hanging from them.
I've been using 1.0mm2 T&E for domestic lighting circuits since metrication, and have never come across 1.5 installed by anyone else in 'normal' houses. The only time I've used 1.5mm2 is in very large houses where VD, etc., come into consideration.I had neevr seen it installed or for open over the counter sale until around 10 years ago.

Rule of thumb is not a correct method for circuit design what is 'paramount' is correct circuit design based on many factors.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.

Local wholesalers have always had pallets of 1.0mm2 T&E on the floor, but only a few reels of 1.5 on the shelf.
Older than me Brian lolMetrication was an amendment to the 1966 14th edition, issued in 1970, so I presume I've been using 1.0mm2 since around then.
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.Rule of thumb is not a correct method for circuit design what is 'paramount' is correct circuit design based on many factors.

Most of the time lighting cable was vastly oversized.
It is an opinion based on fact whilst rule of thumb is based on what exactly. Using 1.5 for domestic lighting circuits is not the norm as I have already stated 1.0 has been in use for at least fifty years. What are you basing your 'opinion' on.You are giving an opinion.

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.I've been using 1.0mm2 T&E for domestic lighting circuits since metrication, and have never come across 1.5 installed by anyone else in 'normal' houses.
