Final answer:
The correct answer is option A. A piece of electrical equipment with a UL label on it shall be installed in accordance with the manufacturer's instructions and specifications.
Step-by-step explanation:
The correct answer is option A. A piece of electrical equipment with a UL label on it shall be installed in accordance with the manufacturer's instructions and specifications. UL stands for Underwriters Laboratories, which is a global safety certification company that tests and certifies products for electrical safety.
Following the manufacturer's instructions and specifications is important to ensure the safe and proper installation of the electrical equipment. This includes considerations such as proper wiring, grounding, and usage.
For example, if a UL-listed appliance requires a specific voltage or circuit configuration, it is important to follow those specifications to avoid electrical hazards and potential damage to the equipment.
This ensures the appliance operates within its designed parameters and maintains the safety certification provided by the UL label. These instructions typically cover the proper electrical load, which is usually rated in amperes, and the way the device should be grounded and connected to the power supply, often utilizing a three-wire system to prevent thermal and shock hazards. Following manufacturer's instructions helps prevent issues that could arise from incorrect installation, such as electrical fires or malfunctions due to excessive current which can trip circuit breakers or blow fuses.
