Re: Electrical wiring

Jesus,
Sorry but it sounds like you are going to be changing some wire. The color code rule reflects generally accepted wiring practice and that is why it is specific. Sensors and other COTS devices that are supplied with wire of a different color are acceptable. i.e. the photo sensors in the KOP. Your mentor had the right idea as color coding is often used with multi-conductor cable. We use a 3M product that is available from Digikey. It is a package that contains a couple of yards of ten different colors of 1/4" wide tape in a dispenser. Everything used in a particular circuit gets the same color code. The motor, the controller, the wiring to the motor, the PD wiring, the breaker, the PWM cable and the position on the DSC, analog module or solenoid module all get the same color. That way if the red motor is not running, one checks the red speed controller to see if it is lit, then the red breaker if there is no power or the red PWM cable to see if it has pulled out.
