Re: under-cabinet lights
Sitting here building a final exam for my NEC class when it hit me like a storm.
In 210.11 Branch Circuits Required Branch circuits for lighting and for appliances, in 210.11 (C) I am told that I am required to in install small appliance, laundry and bathroom circuits and they must have a 20 ampere overcurrent device.
When I get ready to calculate the load for the service I use Table 220.12 General Lighting Loads by Occupancy. Note the title of this table.
Well I am a easy instructor and I am going to let the class have the easy one, yes the Optional Feeder and Service Load Calculations for a Dwelling Unit as outlined in 220.82
Let?s look at (B) General Loads. Hey here in 1 what does that say?
3 volt-amperes/ft 2 for general lighting and general-use receptacles. I guess that the general lights and receptacles are to be on the same circuit.
Guess what? In 2 I can add in the small appliance and laundry.
In 3 and 4 I take the name plate rating.
This should make it very easy for anyone to see that other than those circuits outlined in 2,3,4 and part (C) of 220.82 are lighting outlets. Every receptacle outlet in the house and the required outside receptacles except those outlined by 2, 3, 4 and (C) are part of the lighting load. To plug a lamp or fixture in one of these receptacles would be connecting it to the lighting circuit and no problem. This is where they figured to be in the first place.
They was nice enough to allow us to include the small appliance and laundry circuit in the rating of the service so why would we want to intermingle the circuits together.
They have been very careful to point out that there is a difference in the circuits and also mandated that the small appliance and laundry circuits are to have no other outlets. 210.11 (C) (2) for the laundry and 210.52 (B) (2) for the small appliance.
George you made reference to 210.6 three times above but not one of them make mention to Luminaires (lighting fixtures) and they are outlined in A, B, C, and D. E doesn?t mention them although only A applies to dwelling units.
I took note that you also pointed out 422 for fastened in place appliances and also went to ARTICLE 640 Audio Signal Processing, Amplification, and Reproduction Equipment and ARTICLE 695 Fire Pumps.
I thought we was debating the small appliance and lighting outlets. I have tried to remain in 100 and 210 except as referenced elsewhere. This time I did jump to 220 for a different visual of the three major multioutlet circuits allowed by the code in dwelling units. I have quoted article and section that mandated that a light fixture be install on a general purpose circuit and article and section that forbids the lighting fixture to be installed to a small appliance circuit. So I ask for some to show me an exception that allows the lighting outlet or fixture to be supplied by the small appliance circuit.
