What is the proper way to interpret Article 220-14 (A-L) as it relates to a manufactured, field installed wiring harness for Teknion office work stations. We are using a 8 wire harness which consist of a 3 wire isolated computer circuit & 5 wire, 3 circuit for general use. This harness is installed in a built-in raceway, with the tri-plex receptacles mounted in the top of the raceway, facing up. This leaves the outlets behind a flip up door at desk top height.
My first question, is this a ?Multioutlet Assembly? as defined by the code?
If not, then how do you calculate the branch circuit load? Taking into account that the tri-plex receptacles that we are using have all 3 circuits on one strap. The 3 outlets are not physically mounted on a common strap as a normal duplex, they are 3 separate outlets that are terminated in a common connecter that plugs into the harness & snap into a common pre-punched opening in the raceway. There are no exposed terminals on the back side.
My take on this is that you are allowed 13 total receptacles on one three phase group.
My last question, does this tri-plex receptacle come under Article 210.4(B) Multiwire Branch Circuits?
