A neat little pull-cord on a shower circuit will overheat and fail — it was a 6A lighting switch on a load pulling forty times that. This guide covers why bathrooms use a ceiling pull-cord at all under BS 7671 zones, how to match the rating (6A for lighting and fans, 45A or 50A double-pole for a shower), and why the shower switch must be double-pole.
A cable reel rated 13A can melt if you run a heater off it while it is still wound — and it is physics, not a fault. This guide covers why a coiled reel overheats, the wound-versus-unwound rating on the drum label, why a thermal cut-out matters, and how to pick between open, cassette and metal-drum reels.
