    Demand Load = 4,00, * = VA. I = / = A. Question 5 of 9. After the demand factor is applied, what is the general lighting load of a hospital which is hav sq ft area? As per NEC Table , The unit general lighting load for hospital is 2 VA per sq ft. So total lighting load of hospital = 80, * 2 = 1.

Mike Holt worked his way up through the electrical trade from apprentice electrician through electrical contractor, to become one of the most recognized experts in the world as it relates to electrical power installations. He was a Journeyman Electrician, Master Electrician, and Electrical Contractor.

InMike realized there was a need for quality electrical training and opened. Knowing how to correctly size loads in commercial applications is an essential skill for electricians.

Even if you work with stamped drawings, you'll eventually need to do commercial load calculations in the field or on a licensing exam. The NEC covers commercial calculations in Art.

but other articles also apply. Whether pro or novice, you'll find the key to better, faster, and cheaper electricaldesign for commercial buildings inside this book.

About the Author William H. Clark, II is a registered professional engineer with wide experience in electrical, lighting, /5(8). Electrical Master/ Contractor Calculations Library - Mike Holt You must master electrical calculations to be successful in the electrical trade.
