Question

wiring and protection
use the information below to answer the question
chapter 2 of the national electrical code (nec)
focuses on the wiring and protection of electrical
systems. in this chapter, article 210 addresses
grounded conductors, which are typically identified
by the colors white or gray. article 210 delves into
branch circuits, outlining the installation of ground
fault circuit interrupters (gfcis) and arc flash circuit
interrupters (afcis).

article 215 explains feeders, which are conductors
running from the load side of a utility meter to the
line side of the first overcurrent safety device.
electrical calculations are covered in article 220,
while article 225 addresses outside branch circuits.
lastly, grounding and bonding are discussed in
article 250. these nec articles collectively provide
comprehensive guidelines for ensuring the safe and
efficient operation of electrical systems.

in chapter 2 of the nec, what is the focus
of article 220?

calculations
branch circuits
grounded conductors
feeders
