Low quality UK consumer units.

Sparkingchip

For a long time I have believed that UK consumer units and their components are a lower quality than is generally used in Mainland Europe.

Take for example this Hager SPD and compare it to what is available in the UK.

Hager surge arrester type 215kA
The self-protected Hager surge arrester is equipped with a disconnection device in the event of a short circuit.

its self-protection eliminates the need to protect the surge arrester with a circuit breaker

this Hager surge arrester is ideal for installations with limited power connections (blue tariff) for residential buildings and professional premises

So why is this available and installed just over twenty one miles away from the UK, but not here?

    Higher risk of voltage disturbances?

    Before getting too far into the discussion, assuming you want a discussion, there are already some literally massive changes to UK domestic consumer units being put into practice.

    Above AQ2 in the red bits on the map.

    Skip through and watch the part with the coffee machine.

    This isn’t meant to be about SPD, the whole assemblies just seem to be better quality.

    Using all of those materials will cost the planet. The Chinese will be rubbing their hands together with the need to produce more. I reckon that there will be technicians attending these overegged houses every month due to breakdowns of the over complicated installations. The maintenance/breakdown costs will be very high.

    I feel sure that the wardrobe-sized CU is because the properties are experimental. Somebody is collecting a lot of data. I assume that each of the rows of SP devices is being metered separately, otherwise everything would fit into the central panel. A 4 x 3-way TPN board should be plenty.

    I would like to know how the SWA tails are connected in the meter box.

    Lol… perfect …that's the end of understairs consumer units. Althought, I might suggest It would need to be full wall height (2.4m) so all the cabling enters and leaves both top and bottom without the need to be installed under plasterboard. But then what should we do with our existing housing stock?

    Hager surge arrester type 215kA

    Just for clarity - that's a type 2 rated at 15kA (rather than 215kA).

    Raise the ceiling to 2,4m to accommodate the CU, or more likely put it in a shed outside to go rusty.

    UK building regs do not specify a ceiling height.
