There are two contacts in a circuit breaker: a fixed contact and a floating contact. -
ANSWER ✓ true
Liquidtight flexible metallic conduit (LFMC) has an overall non-metallic outer
covering that is not waterproof or resistant to cracking from sunlight exposure. -
ANSWER ✓ false
A very simple example of a motor control mechanism is a variable frequency
drive (VFD), which adjusts motor voltage, changing the rotation speed. -
ANSWER ✓ true
Common wire sizes are 10, 12 and 14 - a higher number means a larger wire size,
and affects the amount of power it can carry. - ANSWER ✓ false
Each application requires a certain wire size for installation, and the right size for
a specific application is determined by the code. - ANSWER ✓ true
RMCs are both light and inexpensive. - ANSWER ✓ false
To prevent drips and water-logging in the conduit runs, install drains at the lowest
points of each run that might be affected, or at locations where water might get
trapped and accumulate. - ANSWER ✓ true
An installation may require a lot of bends, and bending conduits on location might
damage them or reduce the internal diameter. - ANSWER ✓ true
Conduit bodies are tubular units with openings at each end for admitting conduits,
and providing access to the wires. - ANSWER ✓ true
,One great advantage of flexible metallic conduit (FMC) is its ability to absorb
vibrations and allow movement, so it is often used to house wiring for pumps,
motors and manufacturing equipment. - ANSWER ✓ true
Rigid metal conduit (RMC) usually has the toughest and thickest walls made from
coated stainless steel or aluminum, so they offer excellent protection against
impacts, punctures and cuts. - ANSWER ✓ true
PVC conduits are available in both Schedule 40 and 80, which are basically ratios
of the thickness of the wall to its outer diameter. - ANSWER ✓ false
Aluminum conduit is one type of metallic conduit. - ANSWER ✓ true
Since electrical conduits are essentially a safety feature, you should select the
material, size and fittings based on the environment of the installation and the type
of wiring it will be housing. - ANSWER ✓ true
Fittings for electrical metallic tubing (EMT) are both readily available and
inexpensive. - ANSWER ✓ true
Mechanical lugs are available bolted with two screws or with four screws. -
ANSWER ✓ true
Unshielded twisted pair cables (UTP) are more affordable than coaxial or optical
fiber cables, so UTP cables are often used in telephones, security cameras and data
networks. - ANSWER ✓ true
Electrical nonmetallic tubing (ENT) can only be used outdoors, in areas where
they will not be exposed to physical damage, hazardous conditions, temperatures
over 50°C and the conductors do not carry over 600 volts. - ANSWER ✓ false
The National Electrical Code and Local Building Codes regulate the manner of
installation and the types of wires and cables for various electrical applications. -
ANSWER ✓ true
Nipples are threaded on both ends and can be installed quickly and easily. -
ANSWER ✓ true
, Three methods of mounting circuit breakers: fixed mounted; removable mounted
and drawout mounted. - ANSWER ✓ true
Liquidtight flexible metallic conduit (LFMC) is durable and strong; therefore, they
can be exposed to stresses or encased in concrete. - ANSWER ✓ false
A Schedule 80 conduit will have a thinner wall than Schedule 40, so it is not
permitted for installations where the conduit will be exposed to physical stresses. -
ANSWER ✓ false
Electrical metallic tubing (EMT) is light and bends easily. - ANSWER ✓ true
Mechanical lugs are suitable for brass lightning protection and where there may be
plenty of vibration - ANSWER ✓ true
Direct-buried cables (DBCs) have high tolerance to temperature changes, moisture
and other environmental factors. - ANSWER ✓ true
A bushing is 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. - ANSWER ✓ true
For coaxial cable, the two inner shields share the same geometric axis. -
ANSWER ✓ true
Triplex wires are usually used in single-phase service drop conductors, between
the power pole and weather heads. - ANSWER ✓ true
The adjustable speed drive is a unified combination of devices that enable
operators to drive as well as adjust the operating speed of a mechanical load. -
ANSWER ✓ true
RMCs are usually called 'thinwalls', since they have a much thinner wall than
others. - ANSWER ✓ false
Wire Lettering: H represents heat resistance and W represents suitable for wet
locations. - ANSWER ✓ true
