ELECTRICAL INSTALLATION
COMPREHENSIVE EXAMS SET TESTED
QUESTIONS AND CORRECT ANSWERS
●● bonding
Answer: connected to establish electrical continuity and conductivity:
the purpose of bonding is to establish an effective path for fault current
that facilitates the operation of the overcurrent protective device
●● bonding jumper
Answer: a conductor used to ensure electrical conductivity between
metal parts that are required to be electrically connected
●● concentric knockout
Answer: a series of removable metal rings that allow the knockout size
to vary according to how many of the metal rings are removed; the
center of the knockout hole stays the same as more ring are removed.
●● drip loop
Answer: an international loop put in the service entrance conductors at
the point where they extend to the weatherhead ; the drip loop conducts
rainwater to a lower point than the weatherhead
, ●● eccentric knockout
Answer: a series of removable metal rings that allow a knockout size to
vary according to how may of the metal rings are removed; the center of
the knockout hole changes as more metal rings are removed; common
sizes are the same as for concentric knockouts.
●● equipment
Answer: a general term including material, fittings, devises, appliances,
luminaires (lighting fixtures), apparatus, machinery, and other parts used
in connection with an electrical installation.
●● equipment-grounding conductor
Answer: the conductor used to connect the noncurrent-carrying metal
parts of equipment, raceways, and other enclosures to the system-
grounded conductor, the grounding electrode conductor, or both at the
service equipment.
●● ground
Answer: the earth.
●● gounded
Answer: connected to earth or to some conducting body that serves in
place of the earth
