1.8?

[jdd]

When calculating design current is there any need for me to apply a 1.8 factor to fluorescent lighting with high frequency control gear?
I feel like this is a daft question but just wanted to hear your valuable opinions.

Thanks!

Yes.......

Still discharge lighting.

Oh right, wasn't as daft a question as I'd thought. I thought the 1.8 factor was to compensate for a higher start up current. But now I'm typing this I suppose a type C breaker would compensate for that! Doh!

But not for your cable size.

If I remember rightly the 1.8 compensates for the fact its an inductive load.....

I believe it's only 1.5 for flourescents?
