This year, our team is planning on using 16+ motors. Do the rules allow multiple power distribution boards? If so, what kind of configuration would you put them in?

R25 says "the one (1) Cross The Road Electronics Power Distribution Panel"

With that many motors, I would be more worried about tripping the main breaker than anything else. But yes, there is a practical limit of 16 motors thanks to the PDP outputs.

Well, that's not completely true because according to R42 you may have 2 window motors, snow blower motors and a couple others on one controller and therefore one PDP output.

Given the unlimited motors this year if you're using those motors you're probably doing something wrong.

Or you're out of PDP channels.

Or those small motors provide enough torque and power, but you really need the torque applied in two separate locations, possibly in opposite directions (e.g. take-up rollers).
