Names come from: no legend on this sheet, so NECA 100-2006 is what a name rests on. It is the baseline for what a symbol MEANS, never for matching shapes — proportions differ per firm. Confirming a name here is a correction, and corrections are what build the firm's file.
Scale is UNSET. Nothing on this sheet has been measured. The reader declined to infer a scale rather than guess one, so there is no raceway and no branch wire off this sheet — together the largest block of material on a job of this kind. Set it from the title block and measurement becomes available.
