Electrical level 3 Mod 1 Exam Questions And
Answers
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
, Electrical level 3 Mod 1 Exam Questions And
Answers
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
Ampacity of branch circuit conductors must be derated when -
correct answer ✅There are more than 3 conductors, temperature
exceeds the temperature rating
NEC table 310.16 -
correct answer ✅Lists allowable ampacities for insulated
conductors rated 0 to 2,000
