Per the image, he has a branch circuit tap which would have to comply with 210.19 and 210.20. It doesn't appear to comply to me.
As drawn it looks to me like a feeder supplying a set of 30A OCPD's....based on where the connection (tap) is located I would say it was a feeder to the 30A OCPD and a branch circuit from the final OCPD to the load in this example. It is with nearly 100% certainty the EI would assume this as a feeder tap application.
I wont argue the "it can be both concept"...as this image clearly in my mind (the way it is actually drawn) is a feeder that terminates into an enclosure with 30A OCPD's that feed some LOAD which is not specified. If it did not have the OCPD's located where they are I would have no problem calling it a branch circuit...but at this stage I call it a feeder and those are feeder taps.
To each his own I guess.....I will substitute your logic with my logic and make it happen !:angel:
Definition of Branch Circuit - The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s). Seems to me based purely on this drawing...I have final overcurrent devices (30A) between there and the outlet(s)....now if that was simply a disconnection means only then I would call it the entire thing a branch circuit....but based on how it is drawn I would not...convince me otherwise please as I always like to learn something new.
I might add....if that 30A fuses are "supplemental" then I might buy the branch circuit argument....if these 30A OCPD's are required in the circuit to protect the smaller AWG conductors from the 30A to the load then they are not supplemental.
