Chapter 11 Conductors, Connections, and Protection

___ is two or more conductors grouped together within a common protective cover and used to connect individual components.

Cable

___ is two or more conductors grouped together and used to deliver power to a load by means of a plug.

Cord

A cold solder joint is a good electrical and mechanical connection caused by sufficient heat during soldering.

False

An overload is a condition that exists on an electrical circuit when the normal load current is exceeded.

False

___ is the method of using light to transport information from one location to another through thin filaments of glass or plastic.

Fiber optics

___ is the process of joining metals by heat to make a strong electrical and mechanical connection.

Soldering

A circuit breaker is an OCPD with a mechanical mechanism that may manually or automatically open the circuit when an overload condition or short circuit occurs.

True

A ripcord is a cord included in a cable that aids in removing the outer jack.

True

Insulated conductors are rated based on the current they may safely carry without damaging the insulation.

True

Wire sized by using a number, such as No. 12 or No. 14.

True

___ is any individual conductor.

Wire

___ cable is a cable that has an outer cover made of flexible galvanized steel.

armor clad

___ cable is used to transmit data from one location within a system to another location.

communication

A(n) ___ is a material that has very little resistance and permits electrons to move through it easily.

conductor

___ is a hollow pipe used to protect conductors.

conduit

A(n) ___ connection is a connection in which two wires are held together by crimping them in a specially-designed fitting.

crimped

A(n) ___ is an OCPD with a fusible link that melts and opens the circuit when an overload condition or short circuit occurs.

fuse

A(n) ___ fuse is a fuse that may detect an overcurrent and open the circuit almost instantly.

non time delay

___ cable is a tough, plastic-sheathed cable that is normally made of a moisture-resistant, flame-retardant material.

non-metalic

A(n) ___ bend consists of two 45 degree angles on one piece of conduit.

off set

A(n) ___ is the condition that occurs when circuit current rises above the normal current level at which the load and/or the circuit is designed to operate.

overload

___ is the range of frequencies that is a device can accept within tolerable limits.

panel width

A(n) ___ splice is a splice that consists of twisting two wires together.

pigtail

A(n) ___ is the device at the end of a cord that connects the device to the electrical power supply by means of a receptacle.

plug

A(n) ___ plug is a plug in which one blade is wider than the other blade.

polarized

A(n) ___ is overcurrent that leaves the normal current-carrying path by going around the load and back to the power or ground source.

short circuit

A ___ splice is a splice that connects two wires together when one wire is to remain unbroken.

standard tap

A(n) ___ fuse is a fuse that may detect and remove a short circuit almost instantly, but allow small overloads to exist for a short period of time.

time delay

A(n) ___ splice is a splice that connects two wires that may be placed under a lot of mechanical strain.

western union

A(n) ___ is a solderless plastic connector that uses a tapered metal coil spring to twist wires together.

wire nuts

A(n) ___ is a tool that is designed to properly remove insulation from small gauge (normally AWG sizes No. 10 - No. 22) wires.
