bs 1361 fuse

[i=p/u]

hi ho, i just replaced replaced 8 gu10 50W bulbs in room as were blown. there is 18 on the one circuit plus 3 mini strip lights under benches very likely 18W each, they were all working when i left and when she left room she switched all 3 switches on 1 go and she said the fuse had blown, would you say by her switchen all on one go would of blown the 5A 1361 fuse ?? i personaly think to many but when you add it up its under 5 A

18 x 50W = 900W / 230V = 3.9A
3 x 18W = 54W / 230V = 0.23A so roughly 4A all in, which is under 5A

any input guys before you all go your local niteclub and dance like your up a ladder and fallling

does 50W halogen gu10s use more than they state, think i heard or read somewhere before, or am i loosing it

Any incandescent lamp has an inrush current, hence a tired fuse goes POP

u aint just a pretty dude tony are you.... when i was working there today i found half pack of 5A fuses lying on top of cu .
would you say with the fuse keep blowing would destroy the lamps aswell in some way.

Its like a b Versus a C or D type breaker innit.....slightly different charactaristics for inductives (motors, ballasts, etc)..........

also, it's common for the fuse to blow when a lamp fails (more so with MCBs). an anti-surge (motor rated) fuse may cure your problem though.

well that sounds great telectrix would they fit in to the 1361fuse carrier or am i going to have to change..., i was thinking of changiung the fuse carrier to a 15A one

 

[telectrix]

bad idea.15A is a tad to high a rating for 1.5mm T/E . even worse if it's wired in 1.0mm. better would be to split the lighting into 2 5A circuits.

Could you change the fuse carrier to a 15A, come of the CU in 2.5 to seperate enclosure and fit a 10A MCB?

 

[i=p/u]

isnt 1.5mm rated at 18-20A or something tel. too much work involved in splitting the lighting circuit. ive told them to change to energy efficent lighting (led) just weighing up mu options for monday morning
