BS1363's fusing is a bit problematic for high wattage dimmed lamps too. Not to mention the hastle of climbing or lowering rigging to change a plug fuse!
Generally BS546:1950 ( & ammendements) is just considered an opsolete standard here. Strangely enough though, so's CEE 7/4 (Schuko). Stranger still, BS546 was never an offically recognised standard at all in Ireland it just appeared.
It's difficult to get your hands on spares, the plugs available tend to be hard thermoplastics rather than the rubber variety etc.
