Theory
100

A conducter having no covering or electrical insulation whatsoever.

What is a bare conducter?

100

This device is intended for the protection of personnel that functions to de-energize a circuit or portion thereof within an established period of time.

What is a GFCI (Ground-Fault Circuit Interrupter)?

100

This is the difference in potential between any two conductors

What is voltage?

200

This is the maximum current that a conductor can carry under the conditions of use without exceeding its temperature rating.

What is Ampacity?

200

Connected to establish electrical continuity and conductivity.

What is bonding? (bonded)

200

This household area requires ground fault protection even though it is inside, typically finshed with no A/C.

What is a garage? 

300

A String of outdoor lights that is suspended between two points.

What is Festoon Lighting?

300

this device shall be installed such that at least 8 feet of length is in contact with the soil and provides the connection to earth.

What is a grounding electrode or rod electrode?

300

This classification of a conduit section allows an installer to use 60% of a conduit's fill rather than 40% of the conduit when running wire.

What is a nipple?

400

The overhead conductors between the serving utility and the service point.

What is a Service Drop?

400

This important electrical component shall be used to connect the equipment grounding conductor(s) and the service-disconnect enclosure to the grounded conductor within the enclosure for each service disconnect.

What is a Main Bonding Jumper?

400

The professional practice used when more than 3 current carrying conducters share a conduit.

what is derating?

500

Capable of being reached quickly for operation, renewal, or inspections without requiring certified professionals to take actions such as to use tools (other than keys), to climb over or under, to remove obstacles, or to resort to portable ladders, and so forth.

What is readily accessible?

500

A low impedence circuit capable of safely carrying the maximum ground-fault current likely to be imposed on it from any point on the wiring system where a ground fault occurs to the electrical supply source.

What is an Effective Ground-Fault Current Path?

500

The formula to calculate the wattage (power) used by device, fixture, or appliance

 What is watts = volts x amps
