AJJewsbury:

even omitting labelling happens

Ah, you mean the traditional British coloured dots labelling system?


White dots (a light colour) - lighting.

Blue dots (a water like colour) - immersion heater

Red dots (a hot colour) - for power - sockets or cooker (further sub divided by the red stripes just visible above the fuse terminal shield) - one thick for cooker, two (or more) thin for sockets.


Apparently well known for many years and had the benefit of being language independent (no need for anything different in Welsh speaking households for instance) and in most modest dwellings would uniqely identify every circuit. In larger homes were there might be more than one of each type of circuit you simply had to pull a fuse or two and see what stopped working - not too onerous (and probably more reliable that someone else's labels).


For those with non-standard fuse boxes without the coloured dots there was the "A" series alternative identification system - again language independent - 5A for lighting, 15A for the immersion and 30A for sockets/cooker (often sub-divided in the normal way by red stripes).

No, completely avoiding filling out anything at all on three-phase commercial final DBOs so no-one has a clue what feeds (or isolates) what !

Appalling when:

• equipment similar to the labelling printer I linked to in an earlier post can often be purchased for £30 or under

• Even more cheaply if you already have a laser printer, a number of forms of self-adhesive A4 labels are available (even plastic-based so they are more durable, but paper would provide something equivalent to the supplied labels with many CUs or DBOs), and someone resourceful might use images available on-line, and a Table in Microsoft Word to achieve the appropriate spacing ...
