210.19 is only for conductors.
The 80% rule for overcurrent protection now relies on 219.19 for the 80% only on continuous load, and is in line with the UL wording for breakers.
Much to the chagrin of us oldtimers, the 80% rule was re-written a few cycles ago. What with so many of us that used it for years, and so many of us do only commercial and industrial where everything can be considered to operate more than 3 hours, it is ingrained in us.
For residential, and considering the 180 VA is only for quantity of outlets on a circuit, I see no issue with allowing the counts I stated.
I try not to treat DIY'ers with disrespect, but they are ignorant to to huge amount of detail involved with this trade, and I like to deliver the best, simplest, and accurate info as possible.

First of all I must say I enjoy the technical dialog (with you) immensley - these types discussion are a great base for learning and it is always nice, valuable, and important to to get another's technical opinion - also of interest is the difference in the applicatin of the code in other areas of the country - although as I have travelled around in the course of my work it sometimes "bites" me <grins>... also peer review is a most critical aspect of valid technical info as I'm sure you are well aware and technical 'disagreements' are even more important to ensure one's complete and accurate grasp of the subject (facts) - a great and fun learning experience that I never tire of - kind of like the search for the absolute truth as a professor indicated to me somewhat unkindly many years ago lol... never forgot that.. also your time and interest and feedback much appreciated >>also note - I suppose we should take this type of dialog off the board so as not to consume resources (or is there a discussion area? ) - feel free to email me
[email protected] - tele might even be fun too on occasion (I am from the east coast originally) - spent part of my service time at Ft Devens actually... anyway... on to your reply
>re 210.19 - ahh yes entirely correct - as I realized shortly after I sent it - duh - I should have just left it at "i dont remember lol" :o
>re 80% rule - yes indeed - although again I was only referring to the loading of the OCD - I think labman referred to this recently too as I was browsing around (ill try to find it)
>number of outlets issue - yes - I see no real (or critcal) issue here either just a difference of area application perhaps and/or conservative design - I to am involved mainly in heavy industrial power distribution and some comercial and the 80% is in fact ingrained as you put it... although again in this area - being a house or a 3000A service 80% and 8 outlets it is - most of cook county has very restrictive code application...
>re DIY'ers.. ohhh yesssss.. some of the questions I see here are absolutely frightening and again kudos to you for taking to time to answer so many of them - I wish I had more - usually just brows and read but had some time today for a change to answer... also it loooks to me like you do in fact provide valuable technical help indeed and I surely hope that it is heeded - I see many receipes for disaster on here...
>that's it for now - thanks again - and do consider contacting me directly... take care, rg
