The Swiss Way

Roger B


We recently had our kitchen rebuilt and at the same time the distribution box was updated. Here are a few pictures to show a non UK installation. The supply is 3 phase 20A per phase. Lights and sockets are generally 1.5mm2  singles in conduit. Appliance power (2 or 3 phase) is usually cables in conduit. Sockets and lights are on the same circuit for a large room or a number of small rooms. Neutral used to be yellow and is now blue. Phases are red, white and black. Circuits after the switch can be any other colour.

The bottle fuses were for the appliances, 2 phase for the oven and hob and 3 phase for the dishwasher. The Bathroom and toilet had an RCD. The bedrooms and living room MCBs with neutral isolators.

    Ah, so the box with the 3 blade fuses is also, presumably, the place where the N-E bond and TNC-s split occurs. They obviously don't share our desire for lots of green and yellow singles to rush off from a MET at tht point to the water fuel pipes for the heating and so on. You had me looking up ceander, to find it is a trade name for wave concentric or 'wavecon'.

    Thankyou, it is interesting to compare styles, and to remind ourselves of how much of what we see as being set in stone as immovable truth is really our local habit.
