I will be wiring 9 outputs in a J-box. These outputs are 115 vac at .2 amps each. It's possible that up to four of these will be energized simultaneously. Each should be grounded. The question is how many and what size grounds and commons should be run between the J-box and the control panel? (a distance of about 15'). I also have 8 inputs (24vdc) that i'd like to wire in the same J-Box and would like to know how many commons i'll need for that. Any help/education would be greatly appreciated.
