Wagos on Final Ring Circuits

Will this thread run for a full week?

You never know. Have fun while it lasts.

Regarding radials in other countries, I have always been uncomfortable with them not having fuses in the plugs, as is standard in the UK

 

[LastManOnline]

Europeans are completely comfortable not using fuses in plug tops because they are not required. Using the same adiabatic equation they can very safely plug their appliances into 16amp protected circuits. Fused plugtops in UK and Ireland on the other hand are obligatory due to the ring circuit having 32 amp circuit protection

A 0.75mm flex is not protected on a 16A radial. The maximum rating for a 0.75mm cable is 6 amp. It needs 6 amp or lower protection, not 16 or 20 amp. Run 20 amps through a 0.75mm flex then see what happens to it.

Overload protection can be omitted for a fixed load, as it's not possible for 20 amps to flow in this scenario.

SO I believe. But I have known a few table lamp fires in my time, and we have fuses in the plugs as well. OK they probably had a 13A fuse, not a 1A. But we have the ability to give greater protection, they do not in the basic designs.

Who said a 0.75mm flex IS protected by a 16a radial???. I think you may have misread my comment.
Furthermore as stated by a previous poster, an appliance is an "end of line" accessory which does not require overload protection, it simply requires short circuit protection.
I believe the Europeans had that figured out some time ago.

I have never heard of a table lamp fire. Can I ask where these occurred and under what circumstances?

candle lamps?

any roar 7 pages on a thread about wagos. that's more pages than in the Wago sales brochure.

To be fair to OP, I thought he made an intelligent argument regarding use of WAGO connector in a ring circuit, though under scrutiny it ran out of steam. It did however hold my attention. I found the reasoning on "table lamp fires" much less persuasive.

I will take pics of my fused lamp sockets next time i am in Spain. FYI, some of the light switches, such as those that operate wall-mounted bedside lamps and others, also have fuses in them.

In that case you can start a lucrative business in the UK changing ceiling rose, s

LIghting circuits are on 20A mcbs? New on me.

Sounds good. Looks like the Spanish have come a long way. When I was a kid I recall seeing the bell wire i the ceilings, they used for lighting circuits as they built those shoddy hotels.

I recall as kid we smelled burning in a bedroom. My sister's table lamp was melting - around the switch. My Dad pulled the plug out, taking the smelly lamp outside. I recall it had a 13A fuse in the plug, as it was brown coloured, not a 1A. An electrician neighbour told us put a 1A fuse in table lights. He also went around the house telling us what fuse value to put in the plugs as well. We were lucky we got there soon enough. A 1A would have saved it. That was just in our house.

You seem to think lamps will not develop faults.
