So you Want to be an Electrician? Quiz

Answer: Red

Gray, white, or green with a yellow stripe are the acceptable choices for a grounded (or neutral) conductor. Wires of any other color (including red) are ungrounded conductors (or hot wires).

Knowing the difference between a grounded conductor and an ungrounded one is very important since grabbing the wrong wire is potentially dangerous (and shocking).

Answer: amperes

The ampere is usually referred to as an 'amp' and is named for the French scientist Andre-Marie Ampere. It can also be abbreviated by a capital A. The ampere is defined as the flow of about 6.24 quintillion (6x10 to the 18th power) electrons per second.

An ammeter is the device that is used to measure current. The milliampere (or 1/1000 of an ampere) is a commonly used subunit.

Answer: plastic bushing

The NEC states that all conduit connectors entering a box must have a plastic bushing for protection, if the wire is size #4 or larger. The bushing provides a smooth, insulated surface. Failure to use the bushing could lead to a short circuiting or a fire. The plastic bushing is a cylindrical mechanic or electric component. It reduces friction or wear between moving parts.

The NEC generally requires that conductors be safely enclosed.

Answer: Switched receptacles

A switched receptacle typically uses a wall switch (on/off) to control things. Switched receptacles in bedrooms and family/living rooms are an option instead of ceiling lights, but they are not a requirement. The small appliance circuits include all floor and countertop circuits. The lighting outside of exits also applies to commercial and industrial facilities.

Answer: within three feet of the basin

This rule is intended to eliminate the chances of electrical cords hanging over the sink. In addition to being within three feet of the basin, the outlet should be within twelve inches of the countertop. If there is more than one basin, the requirement needs to apply to each basin.

This meets the requirement of the NEC (National Electrical Code).

Answer: smoke detectors

Smoke detectors are life savers, giving occupants time to escape a fire. Smoke detectors are required on every level of the home plus in every bedroom of the home. It is also recommended to keep smoke detectors some distance away from heating sources including cooking appliances.

Answer: Open incandescent light

Open incandescent bulbs are considered a fire hazard. In addition, hanging light fixtures (which could easily become entangled) are discouraged.

The lighting fixtures that are used in a closet should be fully enclosed.

Answer: Copper

Aluminum is a good conductor, but the easy availability of copper, and its proven track record, means that this is the conductor of choice in most applications. The copper wiring is usually encased in plastic which is meant to prevent the electric current from escaping.

Wood is a poor conductor and silver would be too expensive.

Answer: Outlet

An outlet is a point at which power is used. Switches and thermostats only control power. This includes, but is not limited to, where you would insert the plugs. The outlet where power usage is differentiated from power transmission.

Answer: Radiant

While radiant heat can be useful, it is not very cost effective. Radiant heating can also be considered zone heating as each room has its own. Baseboard heating is often electrical but is not required to be.
