I?m looking at a school project that requires breaker panel replacement. The specs call for all circuits to be replaced with new wire to the first utilization device. My problem is the existing circuits all use shared neutrals 3 hots and a neutral. The new requirements call for dedicated neutrals to the first utilization device. Is there a problem tying all the neutrals together after the first device for each phase conductor? It would seem at some time you may me tying one or two maybe three new neutrals to a single sheared neutral? I also understand pipe will have to be added to accommodate the new fill. Please post your thoughts or comments I have not run into this type of request it seems senseless.
