310.15(B)(6) states that the neutral service and/or feeder conductor can be smaller than the ungrounded (hot) conductors, provided the req's of 215.2, 220.22 and 230.42 are met. Is it okay to size the neutral service conductor the same size as the Minimum Service conductor?
The sizing of the service conductor is based on fastened-in-place appliances and other equipment utilizing a grounded conductor.
Most of the buildings that I provide service to do not have equipment specified yet. What happens if more equipment is added to the building later in time? Does the neutral conductor that was sized per equipment at the design stage have to be replaced later because the neutral conductor demand changed? Is there anything wrong with just sizing the neutral service conductor the same size as the minimum service conductor, as long as its not smaller than the required grounding electrode conductor specified?
