Matt, I suspect that you've made a good decision regarding the single heavy gauge dedicated line. As a point of info regarding the 2.8 amp measurement, though, I would by no means assume that an electrician's current meter necessarily (or even probably) has sufficient bandwidth (i.e., is fast enough) to capture the narrow high amplitude current spikes that are likely to be drawn by the amplifiers at times. Especially in the case of Class D (and also Class AB) amplifiers, whose current draw fluctuates widely with the dynamics of the music.
On another note, let me add my second to the many expressions of appreciation that have been made for the time and effort you are putting into performing and writing up this effort, which is and will be of considerable benefit to many.
Best regards,
