WebNEMA Electrical and Schematic Symbols Standards WebWhen designating phasing at unusual or very complex intersections, one may need to resort to what is commonly referred to as non-NEMA phasing, or a non-NEMA phase rotation. Non-NEMA phase rotations are called such because the phase numbering conventions generally associated with NEMA are not followed. For example, in a non …
