Do rules allow multiple PDBs?

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?

Re: Do rules allow multiple PDBs?

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 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).
