Synopsis:

The book demonstrates to the electrical engineer on how to perform SANS 10400XA and SANS 204 lighting calculations, energy calculations of ceiling fans, commercial kitchen equipment such as gas/electric griddles, ovens, fryers, deck ovens, holding units, combination ovens, thermostatic and non-thermostatic loads, etc.

The book is presented in a Q&A format for ease of understanding and application.

The full list of topics covered are reflected in the table of contents. A snippet of a section of the book is also included.
