1.
To the authority having jurisdiction.
Correct Answer
C. Approved
Explanation
The term "Approved" refers to something that has been officially authorized or accepted by the relevant authority or governing body. In this context, it implies that the item or component being referred to has met the necessary standards or requirements set by the authority having jurisdiction.
2.
A point on the wiring system at which current is taken to supply utilization equipment.
Correct Answer
A. Outlet
Explanation
An outlet is a point on the wiring system where current is taken to supply utilization equipment. It is a device that provides electrical power to appliances and devices through a plug. Outlets are commonly found in homes and buildings, and they allow for the safe and convenient use of electrical devices.
3.
Connected to earth or to some conducting body that serves in place of the earth.
Correct Answer
D. Grounded
Explanation
Grounded refers to the state of being connected to the earth or to a conducting body that acts as the earth. Being grounded is important in electrical circuits as it helps to prevent electrical shocks and ensures the safety of the system. When a circuit is grounded, any excess electrical charge or fault current is directed safely into the ground, reducing the risk of damage or injury. This connection to the earth provides a reference point for voltage measurements and helps to stabilize the electrical system.
4.
The conductors from the service point to the service disconnecting means.
Correct Answer
A. Watt
Explanation
The given statement refers to the conductors that connect the service point to the service disconnecting means. It does not mention anything about grounded or thermopile. The term "Watt" is not relevant to the given statement and seems to be unrelated. Therefore, the explanation for the correct answer "Watt" is not available.
5.
An outlet where one or more receptacles are installed.
Correct Answer
B. Receptacle Outlet
Explanation
A receptacle outlet is an outlet where one or more receptacles are installed. Receptacles are the electrical devices that allow you to plug in and connect various appliances and devices. Therefore, a receptacle outlet is a specific type of outlet that has receptacles installed in it, allowing you to power and use multiple devices at once.
6.
The greatest root-mean-square (effective) difference of potential between any two conductors of the circuit concerned.
Correct Answer
D. Voltage (of a circuit)
Explanation
The correct answer is Voltage (of a circuit). Voltage refers to the potential difference between two points in a circuit. It represents the amount of electrical potential energy per unit charge. The root-mean-square difference of potential is a measure of the effective voltage in a circuit, taking into account both the magnitude and frequency of the voltage. Therefore, the greatest root-mean-square difference of potential between any two conductors in the circuit represents the highest voltage in the circuit.
7.
More than one thermocouple connected together. The connections may be series, parallel, or both.
Correct Answer
C. Thermopile
Explanation
A thermopile is a device that consists of multiple thermocouples connected together in series or parallel, or both. When exposed to a temperature gradient, each thermocouple in the thermopile generates a small voltage. By connecting multiple thermocouples, the voltage output of the thermopile can be increased. This makes the thermopile suitable for applications that require higher voltage outputs, such as powering electronic devices or measuring temperature differentials. Therefore, the given answer "Thermopile" is the correct choice as it accurately describes the device formed by connecting multiple thermocouples together.
8.
A device that responds to when the temperature rises at a rate exceeding a predetermined value.
Correct Answer
A. Rate of Rise Detector
Explanation
A rate of rise detector is a device that is designed to respond when the temperature increases at a rate that surpasses a pre-determined value. This means that if the temperature rises too quickly, the rate of rise detector will be triggered and respond accordingly. It is commonly used in various applications where monitoring temperature changes is crucial, such as fire alarm systems or industrial processes. The rate of rise detector helps to ensure safety and prevent potential hazards by alerting users when the temperature rises rapidly.
9.
Indicates a recommendation or that which is advised but not required.
Correct Answer
C. Should
Explanation
The term "should" suggests a recommendation or advice, indicating that something is advisable or recommended but not mandatory. In the context of the given symbols, "should" implies that the action or condition represented by the symbol is not required, but it is suggested or recommended to follow or achieve a desired outcome.
10.
A screw or a quick-connect device where a conductor(s) is intended to be connected.
Correct Answer
D. Terminal
Explanation
A terminal is a screw or quick-connect device used to connect a conductor(s). It provides a secure and reliable connection point for electrical wires or components. Terminals are commonly used in electrical and electronic systems to facilitate the flow of electricity and ensure proper functioning of the circuit. They are designed to securely hold the conductor in place and prevent any accidental disconnection.
