I am looking for an explanation and/or other opinions about the interpretation and calculation of Article 220.14(I) - Multiple Receptacles calculated at not less than 90 volt-amperes.... 220.14I) states that "A single piece of equipment consisting of a multiple receptacle comprised of four or more receptacles shall be calculated at not less than 90 volt-amperes per receptacle". My interpretation is that this means a power strip or a power strip type device that is installed in/to a piece of equipment. By definition of "Receptacle", the four or more receptacles would have to be on the same yoke. By definition of "receptacle" a multiple receptacle is 2 or more "contact devices" (plug-ins) on the same yoke. So when 220.14(I) states "four or more receptacles", I would interpret that as four or more "contact devices" (plug-ins) on the same yoke. Also meaning that the NEC wants you to calculate 90 volt-amperes per "contact device" (plug-in), which means "four or more" would be a minimal of 360 VA. This has nothing to do with a quadraplex receptacle outlet. The only way this code rule would apply is if you would consider a "yoke" to be an entire power strip device because it is mountable, or an integral part of a piece of equipment. So basically this code rule applies to nothing we usually see in the electrical field. Thoughts?
 
the intent of the rule you mentioned in 220.41 I is for this device. I have installed many, no need to open up the wall to install a 2 gang mud ring or box. There is an adapter plate to use on a single gang opening.

I believe it also refers to a hard-wired multi-outlet device, including hard-wired power strips such as Plugmold:
