Hello, Standard NF C 15-100 recommends 8 points max for lighting circuit lighting 1.5mm Â² protected by a 10A breaker. But how to count bright spots?
The definition of bright point in asking me question it.
a) A wall switch that controls two account for 1 or 2 points of light? (I say 2.) B) lighting with spotlights attached to a transformer, how bright point count (1 or the number of spots)? (I say I know nothing:).)
If it comes back to the basic formula P = xi, could be at 2200W max. If we consider a point of light = bulb (60W), one arrives at a consolation of 480W. Which is low compared to the limit hence my question about the counting of light point.
Hello, Indeed, the standard allows for some interpretation, which is not always simple. You already have the answer in your logic. Two patches account for only a single point of light. A transformer feeding spots in LV also. It would have been better than the standard provides a limt of power per light, unfortunately
Hello The standard is very specific on this subject "8 points of light" and non-ignition point, to make it simple let's say 8 sockets (2 = 2 points sconces light) Each circuit 2400 W, has 300 VA by point, even for low voltage therefore also 8 = 8 points of light spots !
courjus Hi, I think following publishers and/or editions, there are some differences that can induce bad understanding. (I speak for me) Are you sure the 300VA limit per item, which is paradoxical for two points with two sconces. Maybe can you also tell me what editor or edition, to be sure to have good info. Thank you in advance. Good day !
