lighting

[peteludman]

just a stupid question my brain is a mess at moment.

i want to fit another 10 fluresent lights high frequency on top of 10 of the same lights so 20 all together the tubes are 26 w 1 tube in each.

i get 2.2A for the lot so a 10A breaker would be fine and switch would be fine to.

is this the right way of working it out, looking at the tube wattage i know there would be a start up current but a type c breaker would take that wouldnt it

just let me know if im wrong or right and just being stupid

thanks

when calculating current for cable calculations or switch gear etc for fluorescent lights i think it is usual to multiply by a loading factor of 1.8.
So even a type B, 6A mcb should be ok - a 10 A mcb would still be fine for protecting 1.5mm cable if the installation method is nothing out of the ordinary.
