Re: Outlets Per Breaker
Article 220 looks like a totally different animal now, I'll be interested to see how Sam, with his 2002, is going to talk shop with Rod and Al with their 2005's.
One of these days, I guess I ought to try to figure out the "new" right way to do calculations.

Re: Outlets Per Breaker
Another example might be 220.14(H) regarding fixed multiloutlet assemblies. The requirement is that every 5 feet of a muiltoutlet assembly be calculated for 180VA unless the assembly would be for heavy use say in a store displaying TV's where every outlet may have a TV plugged into it. The latter scenario would require a calculation of 180VA per 1 foot. So if this were installed in a heavy use scenario could we still install it at 180VA per 5 feet or would the installation have to reflect the calculation with factor of 180VA per 1 foot? Does the NEC require that we use portions of Article 220 for actual installations?
I guess that the real issue here is whether article 220.14 is really about load calculations or actual installations as some have mentioned already in this post. The explanatory material (Exhibit 220.4) provided in the 2005 Handbook clearly indicates that a 15 amp circuit can have only 10 receptacles and a 20 amp circuit can have only 13. This seems to be where the confusion is since it under the article for load calculations. Does that make it mandatory to be installed than way? I'm not sure?

220.14(H) ? ? ?
Somehow I know you mean 220.4(H), right?

An 1800 square ft dwelling unit would only need 3 - 15 amp breakers for the lighting load. This dwelling unit will have about 50 lighting outlets including outside, basement or crawl and attic storage space. This would equate to approximately 16 to 17 outlets per circuit.
Although this installation would be code compliant I have a desire to inject that this will assure you a couple of return trips and added labor and material cost.
Commercial and industrial is a little bit different the receptacles are 180 VA for each duplex and the lights are per the VA load of each fixture.
This will hold true in the past few code cycles.

In 2002 there is no (H) in 220 14 or 4. In ?05 there is no 220.4

Re: Outlets Per Breaker
Thanks, JW,
I'll settle down.
Let me take a moment in my confusion.
For this thread to proceed, the question needs to focus on whether the hypothetical occupancy within which the question is focused is: </font>

Re: Outlets Per Breaker
Exhibit 220.4 is an illustration in the 2005 Handbook. It references 220.14(I) which does not apply to dwellings.
