Certainly appears the reasoning is based upon conflicting code sections to the proposal. To me it read, the established methods 300.22 have proven effective. Seems the proposal did emphasize issues with magnetic currents/over heating and was passed in the ROC as a safety measure. Bottom line - the proposal was voted out 140 to 118 and is not code. Thanks for the info . This will not make my free code change seminar for local sparky's.
