Textbook Question

Chapter 3, Problem 12R

How many lighting branch circuits are provided in this dwelling? __________

a. What is the minimum load allowance for small-appliance circuits for dwellings? See NEC 220.52(A). __________
b. An individual 15-ampere branch circuit is run to the receptacle outlet behind the refrigerator instead of connecting it to one of the two 20-ampere small-appliance branch circuits that are required in kitchens. For this separate circuit, an additional 1500 volt-amperes (shall) (does not have to) be added to the load calculations for dwellings. (Circle the correct answer.)
