LoadTier

LoadTier helps you review how building electrical loads are grouped by continuity needs and what supply arrangements are commonly described for each group. You can explore Grade One, especially critical, Grade Two, and Grade Three loads. Each entry covers definition, judgment points, and supply notes such as dual sources, ring feeders, or single-circuit layouts. Browse building-type examples, scenario cards, side-by-side grade comparison, and local bookmarks stored on your device. LoadTier is a compact reference for people who want a clear overview of load classification and supply planning ideas in building electrical design.
