What is the "industrial standard" wire insulation color for DC motor (90VDC or 180 VDC) leads? I've seen some places that use black and others that use blue. Are both leads the same color? Are the field & armature all the same color? Thanks
Suggestion: The manufacturers do not have to adhere to an industry standard in its entirety, if their product sale reveals that the deviation from the industry standard is more profitable.
