Load calculations—Art. 220 (part 1) Refer to the drawing, and
give the best answer: 1. In doing a load calculation, assume you
have to sum the following loads: 14.75A, 25.49A, and 20.24A.
What is the result for the purposes of applying other code rules
relative to conductor ampacity, etc? 2. The drawing shows
various types of receptacle outlets. In a residence, how many VA
do you need to allow in a general-purpose branch-circuit
calculation for an outlet with the device at the bottom? d. not
specified 3. In a store, how many VA do you have to allow for
two duplex receptacles installed side-by-side in a two-gang box
when you make a branch-circuit load calculation? a. 90 VA d. not
specified 4. In the same store, which of the answers (from
Question 3) would be correct for the device at the bottom? 5.
Again in the same store, how many triplex receptacles (the top
center device) could you put on a 20A branch circuit? Would the
same answer apply to single receptacles (as at the right) if
they were located in groups
