ELECTRICAL LEVEL 3 MOD 1 QUESTIONS
WITH CORRECT ANSWERS | RATED A+
The purpose of branch circuit load calculations is to determine - CORRECT ANSWER -The size of
branch circuit overcurrent protection and branch circuit conductors using NEC



NEC article 210 - CORRECT ANSWER -Covers branch circuits ( except for branch circuits that
supplies only motor loads).



NEC section 210.18 - CORRECT ANSWER -Branch circuits are rated by the maximum rating or
setting of the over current device



NEC section 210.19 - CORRECT ANSWER -Branch circuit conductors are required to be sized with
an ampacity rating that is no less than the maximum load to be served



Branch circuit conductors must have an ampacity rating equal to or greater than the non
continuous load plus - CORRECT ANSWER -125% of the continuous load



NEC table 210.24 - CORRECT ANSWER -Summarize the branch circuit requirements



NEC Article 220 - CORRECT ANSWER -Includes the requirements used to determinable the
number of branch circuits required and the requirements used to compute branch circuit feeder
and service loads



NEC section 210.20 - CORRECT ANSWER -The branch circuit rating shall not be less than the
noncontinuous load plus 125% of continuous load



Continuous loads are calculated at - CORRECT ANSWER -125% of the maximum current rating
