Which statement is true, with respect to the motor installation?a)Wood...
1. Wood is not used for mounting switchgears
2. All equipment used in power wiring shall be of iron clad
3. Electrical looping is loop/loops created between two light with 1 single wire connected to multiple fittings. Usually looping is done for neutral wire. Neutral wire is a return wire for the current in an electrical circuit, i.e. it carries electricity from the output device back to the service panel/board
4. The length of flexible conduit is less than 1.8 m

Statement: All equipment used in power wiring shall be of iron clad.
Explanation:
Introduction:
In electrical installations, it is important to ensure the safety and reliability of the power wiring. This includes the selection of appropriate equipment and materials that comply with industry standards and regulations.
Explanation of the statement:
The given statement states that all equipment used in power wiring shall be of iron clad. This means that the equipment used in the installation, such as conduits, junction boxes, and fittings, should be made of iron clad material.
Reasoning behind the statement:
1. Protection: Iron clad equipment provides protection against mechanical damage and environmental factors. It is more robust and durable compared to other materials like plastic or non-metallic materials. This ensures the safety and longevity of the electrical installation.
2. Fire safety: Iron clad equipment has better fire resistance properties compared to other materials. In the event of a fire, it can help contain the spread of flames and minimize the damage.
3. Electromagnetic interference: Iron clad equipment provides better shielding against electromagnetic interference. This is particularly important in power wiring installations where sensitive electronic equipment is present.
4. Compliance with regulations: The use of iron clad equipment in power wiring installations is a requirement in many electrical codes and regulations. These codes are designed to ensure the safety and reliability of electrical systems.
Examples of iron clad equipment:
- Iron clad conduits: These are rigid conduits made of iron or steel. They are commonly used to protect and route electrical wires in industrial and commercial installations.
- Iron clad junction boxes: These are metal boxes used to house electrical connections and protect them from external elements.
- Iron clad fittings: These are metal fittings used to connect and secure conduits and other electrical equipment.
Conclusion:
The statement that all equipment used in power wiring shall be of iron clad is true. The use of iron clad equipment ensures the safety, durability, and compliance of the electrical installation with industry standards and regulations.
