The Drawer Sizer helps you design drawers for furniture such as an armoire, chest or drawers, or a dresser. It provides three different sizing methods and options within each method for deriving drawer sizes based on the specific inputs provided. Read more about calculating drawer heights. Arithmetic progression: Drawer heights increase by a ...While box-volume calculations are in 314.16 (A), box-fill calculations are in 314.16 (B). Box-fill calculations in 314.16 are applicable for conductor sizes 18 AWG through 6 AWG. Box-fill requirements pertaining to conduit bodies enclosing 6 AWG conductors or smaller are in 314.16 (C). Last month's Code In Focus concluded with 314.16 (B) (2).A great tool to help electricians, engineers and contractors answer the question, "What size conduit do I use per the NEC®?" The app will calculate the conduit fill percentages and jam probability for multiple conductors per NEC® Guidelines. Simply enter the conduit type and size, then specify your conductors.
