  1. It still astounds that just 30 years ago my house had no circuit breakers, we still had the good old fashioned "fuse box", there was no consumer units or MCBs or anything shiny and white with inspection labels on it as we didn't get any of that until around 1994 - no, instead we still had an ugly brown box twice the size of a CU that looked like it was made of bakolite, and shoved in to the front was a dozen big ceramic fuses the size and shape of bourbon biscuits. I remember any time something blew my dad would remove the appropriate fuse cartridge, pull out a snapped/melted chunk of wire and then, spool a fresh piece of wire to it before plugging it back in. I'm glad that now the house is mine I don't have to rely on anything so archaic to keep fires at bay.

  2. A very large room with three entrances, buy a castle and you'll find this setup everywhere.

  3.  @camper1749  I would have ended that with "If you can't figure out how YouTube works, don't bother commenting." :D

  4. Yeah, it annoys me when American channels have British narrators because it takes me longer to figure out they are talking about the US, interesting video all the same but their power set up is nothing like Europe's.

  5. I bet a few 1800's gentleman said the same of Tesla back in the day as he sat under a tesla coil arcing blue flashes everywhere. Must have been so weird after a millennia of stamping out pagans, barbarians and witches and trying to convince the world that magic didn't exist all of a sudden these guys could create light from an invisible source and send lightning bolts from one side of a room to another.

  6. The only point where blue was used as a live wire was in the two conversions and I doubt someone would be happy if you tore out a section of their wall just so you could remove a blue wire and replace it with a brown one.

  7. Try again.

  8. That is true, but in a new build you also have both switches connected to the light whereas in a conversion only the original switch requires being connected to the light, this is why the two conversion variants come in handy as they do away with the need to connect the 2nd switch to the light, meaning less conduit/damage to wall and ceiling.

  9. The neutral is a direct return path to the source so even though the ground and neutral are connected no current will enter you if you touch the ground wire unless you somehow offered a better path to the transformer than the neutral wire does (practically impossible).

  10. Why are so many people struggling to understand what a conversion is? When you add a second switch to a one-switch system then doing the first variant would require a lot more work and a lot more conduit being fitted... "Why have you installed a conduit between the first switch and the second switch, and then another conduit from the second switch to the light? My friend had this conversion done and they only had one conduit that went between the two switches..." "Oh, that's because folks on YouTube told us all this extra damage to your wall and ceiling would be better!"

  11. How can you tell that the left side of the screen leads to the CU and not a junction box?

  12. It was clearly stated in the video that versions 2 and 3 were conversions, that's why they included the word 'conversion'...

  13. I have never seen them called a 3-way switch in my life, so you are literally wrong or literally not from Europe.
