Exam 18: Device Installation

The metal frame that a receptacle or switch is built around is called a(n) ____________________.

The NEC defines a(n) ____________________ as a contact device installed at an outlet for the connection of an attachment plug.

Explain the drawbacks of the push-in method of securing conductors to devices.

The proper NEMA designation for a 30-ampere, 125/250-volt grounding-type receptacle installed for an electric clothes dryer is __________.

On a receptacle, the ____________________ conductor is connected to the silver terminal screw.

Which of the following determine the effect electrical shock has on the body?

If a device box has been installed too far back behind a wall, a __________ can be used to bring the edge of the box flush with the wall surface.

Electricians create a split-wired receptacle by removing the __________ between the brass terminal screws on the "hot" side of a duplex receptacle.

Section 210.12(A) in the NEC requires all of the 15- and 20-ampere, 120-volt branch circuits installed in dwelling unit kitchens, family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sun rooms, recreation rooms, closets, hallways, laundry areas, or similar rooms or areas to be AFCI protected.

If the two conductors to be connected to a single-pole switch are black and a reidentified white, the connection you are using is called a traditional _________________________.

A duplex receptacle that is wired so one half is hot all the time and the other half is switch-controlled is called a(n) ____________________ receptacle.

If a white conductor in a Type NM cable is connected to a traveler terminal on a three-way switch, it does not have to be reidentified because it is not "hot" all the time.

Explain the purpose of the metal strap that runs through or behind a receptacle or switch.

A(n) _________ is a familiar type of transient voltage surge suppressor that is usually bought and installed by the homeowner rather than the electrician.

When a duplex receptacle is installed horizontally, it is recommended that the __________ slot be located on top.

__________ connections on devices are a reliable way to terminate circuit conductors to a switch or receptacle device and can save time during installation because a terminal loop is not required to be made.

A feed-through GFCI receptacle can provide GFCI protection for regular receptacles installed "downstream" on the same branch circuit.

A Class A GFCI device is designed to trip when fault current levels are _____ milliamps or more and not to trip when the fault current is less than _____ milliamps.

A device intended to provide protection from the effects of arc faults by recognizing characteristics unique to arcing and by functioning to de-energize the circuit when an arc is detected is called a(n) ________________________________________.

GFCI receptacles should be tested at least once per __________.
