I seem to remember that the maximum arm span (fingertip to fingertip with the arms stretched out) is usually roughly equal to the person's height, give or take a few cm (for me it's about 50 mm off) so 2.5 m seems to err quite far on the side of caution. Also wasn't the minimum distance of...

Definitely looks like gold H03VV-F 3G0.75 (the size is a guess because I‘ve never seen larger flex in this colour).

Schottky diodes work reasonably well, sometimes even better than NOS Germanium diodes.

Might be time to find someone with a cable tracer and start sleuthing where the other end of the unknown cable is.

The ones commonly used on the continent are push-in style with release levers that need to be pressed quite hard. I can’t imagine the wires coming loose in one of these.

Yes but you can arrange the terminals in such a way that the earth is the last to pull out even if all three conductors are cut to the same length. Screwless sockets are faster to wire than screw terminals and are often thought to be more reliable because the spring pressure can compensate for...

Outside the UK the fan is quite unlikely to be connected to a 32A circuit so it’s not quite the same situation. That doesn’t automatically mean you have to connect the fan via an FCU but it does explain why you don’t need one elsewhere. The most likely reason why you‘d need one (or a BS 1363...

I get strong bticino Domino vibes but that seems unlikely as well.

I know but inferred from the electrician‘s comments that the existing conduit is too small for another three 6 mm2 singles, which means you‘d have to chase for another length of conduit, probably 25 mm.

As far as I know the two single-phase circuit option is only used in the Netherlands but that’s more of an education assumption than factual knowledge.

It will probably work on even a 2.5 mm2/20 A circuit unless you try to put on four pots of cold water at the same time. You definitely want a dedicated circuit though and if you‘re already opening up walls I‘d go for 6 mm2.

Most of Europe had settled on 220/380 or 240/415 V 50 Hz AC for new supplies around WWI but there were plenty of legacy systems in place until well after WWII, both DC and AC with various frequencies and voltages. Electric railways in rural areas would sometimes supply villages along the line...

Sounds like a textbook example of a neutral to earth fault. Any substantial load on the same RCD causes a voltage drop on the neutral, which then causes current to flow from neutral to earth and that trips the RCD. These faults are pretty much impossible to find without an insulation resistance...

The heat generation is pretty much entirely resistive and the big problem with extension leads is lack of heat dissipation.

I‘d be tempted to go with two pendants for ambient lighting and LED battens under the cupboards to light up the work tops in front of anyone standing there. My kitchen is smaller, about 2.5x3 and I‘ve got one hanging light with glass shades and two 6 W LEDs plus under-cabinet lights, the...
