My tenants in the shop have called me out for the third time because the lighting fuse blew when they turned on their miniature halogen chandelier and one of the lamps blew at switch-on. To me, continuously blowing fuses means a faulty appliance, and in this case I definitely blame the halogen chandelier. I hate the things. I should never have installed it for them, but they'd already bought it and "it looks sooooo nice!!!".
Anyway, when I rewired the shop 15 years ago all the lighting is in 1.5mm cables. 1.5mm at "clipped direct", "within non-insulating wall", "floor/ ceiling void" is rated at between 16A and 20A. I'm tempted to replace the
5A lighting circuit fuse with a 10A fuse to avoid transient blowing when a halogen blows. Total circuit consumption is 365W of tubes, 15W CFL and 180W of the halogen chandelier, so 2.3A running total. Any comments?jgh
