Needs some help with ensuring I am within code. I been reading section 220 of my NEC 2011 code book all day and feel I am overlooking something important. I am not rich, so I don't have the 2014 NEC book yet. Out of frustration of not finding what I think exists, I am posting to the forum. This is for a residential application. Is there a safety factor of 20% or something like that I need to use in my load calculations?
I am using less than 20W LED spot lights, however the fixtures are rated for incandescent and to comply with NEC code, I need to base my calculations off of UL approved manufacture lamp specifications. (This is getting inspected)
Using the UL approved manufacture spec., my maximum branch load would be 17A at 120V.
From the panel to the switch is 2-wire 12AWG ROMEX. Both lighting sets controlled individually with one two rocker switch, (not a double pole). From the switch to the 1st fixture is a 3-wire 12AWG ROMEX and a 2-wire from fixture set 1 to fixture set 2.
In your opinion, would I be within code and does this sound like a good idea, or should I split the two lighting sets off and have them on separate branch circuits?
Your feedback is appreciated.
I am creating two separately controlled lighting sets off of one new dedicated luminary branch circuit with the following fixtures.
[*=1](LIGHTING SET 1) 4 motion light fixtures, (RAB STL360 Bullet Flood Kit with 3 lamps per fixture). Manufacture spec is 150W per lamp. This equates to 1800W using 120V as my basis.
[*=1](LIGHTING SET 2) 4 individual can lights that are rated to 60W per can, equaling 240W at 120V.
