CFESA ELECTRICAL FINAL EXAM AND PRACTICE EXAM QUESTIONS 2025
NEWEST COMPLETE EXAM QUESTIONS WITH DETAILED VERIFIED
ANSWERS (100% CORRECT ANSWERS) /ALREADY GRADED A+
Electrical Conduit - ANSWER metal, plastic or fiber pipes designed to protect
electrical cables
Galvanized Rigid Conduit (GRC) - ANSWER a galvanized steel tubing with a wall
thick enough to be threaded
Rigid Metal Conduit (RMC) - ANSWER A thick-walled threaded tubing, usually
made of coated steel, stainless steel or aluminum.
Electrical Metal Tubing (EMT) - ANSWER A thin-walled metal raceway having a
circular cross section; used to pull in or withdraw electric cables or wires after the
tubing is installed in place; uses connectors and couplings other than the threaded
type.
Liquidtight Flexible Metallic Conduit (LFMC) - ANSWER A metallic flexible conduit
covered by a waterproof plastic coating.
Aluminum Conduits: A type of rigid conduit generally used in commercial and
industrial applications where a higher resistance to corrosion is needed.
Polyvinyl Chloride Conduits (PVC) - ANSWER The lightest in weight compared to
other conduit materials, and usually lower in cost than other forms of conduit
Liquidtight Flexible Nonmetallic Conduit (LFNC-B): - ANSWER Refers to several
types of flameresistant non-metallic tubing.
Electrical Nonmetallic Tubing (ENT) - ANSWER A thin-walled corrugated tubing
that is moistureresistant and flame retardant.
Conduit Fittings - ANSWER Fittings used for connecting runs of conduit together,
, and for connecting conduit ends to boxes, enclosures or electrical devices.
Conduit Bodies - ANSWER Tubular units with openings at each end for admitting
conduits, and providing access to the wires.
Bends - ANSWER Conduit fittings commonly called 'factory bends' or 'elbows'.
Coupling - ANSWER Conduit fitting used to securely link together lengths of
conduit and attaching sitefabricated bends.
Drains - ANSWER Conduit fittings used to prevent drips and water-logging in the
conduit runs, especially in areas where the temperature varies significantly, or the
conduit runs from a warm area to a cooler one, and moisture in the air starts
condensing.
Bushings - ANSWER Conduit fittings used to create a smooth entry point to
conduits without any sharp edges, protecting the conductors from damage during
wire pulls. Installed on the inside of the box opening and threaded into the
conduit end, separating the conductors from the edges of both the opening and
the conduit end
Locknuts - ANSWER Conduit fittings threaded on the inside, with teeth on one
surface or both, which grip the surface. Installed on both sides of an opening to
ensure that both the conduit and bushing are held firmly in place.
Unions - ANSWER Conduit fitting with two separate heads and a locking
mechanism which can connect two pieces of conduit together, even if they can't
be physically turned
Nipples - ANSWER Conduit fittings that do not exceed 24 inches in length, these
are threaded on both ends and can be installed quickly and easily. Used for short
runs or between nearby enclosures.
