electrical_pe write: Good basic calculator for single family residential loads, but TINY data entry boxes. Requires too much time and too many errors entering data. Would help to have 2 or more pages. Also would be useful to have residential service sizing table and tables for multi-family calcs, but that is a lot to ask.
