    Metal saddles inside trunking when only 400mm off a concrete floor?

    I'm a bit out of touch re 18th edition. Is it really necessary to fit loads of additional metal saddles inside trunking when it's only 400mm above the concrete ground floor of a sports hall? All the stuff about premature collapse makes sense, but where, in this case, if the cable going to...

    External floor lights, WHY?

    Has anyone seen any of these last more that five years? Even then the work involved in resolving issues becomes crazy expensive. I think these are mostly specified by architects and no sane Spark would suggest them. Here's some I had the misfortune to be asked to "get working", yeah right...

    Height of Zone 1 2.5m above the shower tray or 2.25m off the floor?

    When looking for the height of Zone 1 above a shower, we typically look at the diagrams which show 2.25m above floor level, with no Zone 2 above (although some variants of the zone diagram on various websites do show a zone 2 above a shower). The text however (under 702.32), says Zone 1 is...

    Hey guys, I seem to have come to the right place! I just got a tall floor lamp second hand. It has a main light and an adjustable second. They're both dimmable. The second light works, which is just a 50w capsule bulb. The main light, however, seems more complicated. Anyone got any ideas...
