I was just wondering if it is legal to splice motor wires, essentially running 2 motors off of one port on the power distribution panel.
I suggest that you read R52, then R30.
It depends a LOT on what motors you’re using. Some motors can be run 2/motor controller; many can’t be. No controllers can be wired 2/PDP slot. So if you’re running the right kind of motors, you can get 2/port, but if you aren’t you can get 1/slot.
Splicing motor wires to add length isn’t illegal, BTW.
It would probably be a good idea for @Piconmax to pause and study the whole Game Manual. There may be other rules he/she is not aware of or does not understand sufficiently.
