the word bathroom is defined in NEC Article 100 as an area including a

Basin with one or more of the following: A toilet, uringal, tub, shower, bidet, or similar plumbing fixtures.

All 125-volt, 15- and 20-ampere and 30-ampere receptacle outlets that are not part of the permanent wiring of the building and that will be used by the workers on the construction site must be ______

GFCI protected

what can result when the ungrounded conductor in the appliance comes in contact with the metal frame of the appliance

Insulation failure

is it okay to use AFCI and GFCI devices in series?

It is okay

Will a GFCI protect a person when they touch both circuit conductors at the same time

It will not protect them because it doesn't sense an imbalance

Can you staple flat nonmetallic-sheathed cables on edge?

NO never

Ampacity

The maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating.

locations exposed to direct sunlight require to be listed or listed and marked as what

being "sunlight resistant"

Locations protected from weather and not subject to saturation with water or other liquids but subject to moderate degrees of moisture.

damp location

A location not normally subject to dampness or wetness. A location classified as dry may be temporarily subject to dampness or wetness, as in the case of a building under construction.

dry location

are AC systems from 50-1000 volts required to be grounded?

duh yes

What does the suffix "b" mean (ex. NM-B)

it means conductors have 90*C insulation

what is kcmil

one thousand circular mils

When arcing occurs between the black ("hot") and white grounded (neutral) circuit conductors, or between the black ("hot") conductor and ground, it is referred to as a "parallel" arc.

parallel arcs

When a conductor that is carrying current breaks or when a loose connection occurs, a "series" arcing fault is created. The current draw of the connected load is trying to jump across the opening created by the break or loose connection.

series arcs

rating of the overcurrent devices determines what

the rating of a branch circuit

All 15 and 20 ampere 125 and 250 volt nonlocking type receptacles installed in a damp or wet location are required to be listed as _____

weather resistant type

Installations underground or in concrete slabs or masonry in direct contact with earth; in locations subject to saturation with water or other liquids; and in unprotected locations exposed to weather.

wet locations

when is GFCI protection not required for an outdoor receptacle?

when it is not readily accessible and supplied by a dedicated branch circuit for snow melting or deicing equipment
