E3.1 — ELECTRICAL ROOF PLAN

Roof plan read from the page image; lettering is drawn as outlines, callouts read by eye at each unit.

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 1/4" = 1'-0" — 18 points per foot. Read off the title block, so measurement off this sheet is available. A later correction flags any measurement taken under the old scale as stale rather than silently recomputing it.
