Electrical Load Calculator for Non-Dwelling Buildings


As I explained before that ordinary Non-Dwelling Buildings Loads will be as follows: 

  1. Lighting loads, 
  2. Receptacles Loads, 
  3. Kitchen Loads, 
  4. Heating, Ventilation and air conditioning Loads (Non-Coincident Loads), 
  5. Motor Loads, 
  6. Other Loads. 



For the above Non-dwelling Loads, I explained the following points:

  • Where and how to distribute each type of load in a dwelling unit as per NEC code? 
  • How to calculate its Demand load for feeder and service sizing calculations 



This was done in the following Articles:




Today, I introduce to you, the most professional Excel Sheet for calculating the Total Demand Load for all types of Non- Dwelling Buildings as per NEC Code.
