Which of the following statements is true regarding electrical disconnects?

1. The disconnect must be installed no more than 20' from the serviced appliance

2. The disconnect must be no more than 6 feet off of the ground

3. The disconnect must be in a clear line of view from the appliance

4. All of the above

The correct answer is: The disconnect must be in a clear line of view from the appliance

In addressing the requirements for electrical disconnects, the statement regarding the disconnect having to be in a clear line of view from the appliance is indeed correct. This requirement ensures that the person operating the disconnect can easily see both the disconnect itself and the appliance it controls, which is crucial for safety and operational efficiency. The visibility of the disconnect allows for quick access in case of an emergency or during maintenance, reducing the risk of accidents. While it is true that disconnects have specific placement and height requirements, option C emphasizes the critical importance of visibility, which is fundamental in both national and local electrical codes. This focus on maintaining a clear view supports prompt power disconnection when needed, enhancing safety protocols in electrical installations. The other statements regarding maximum distance from the appliance and height requirements, while relevant to installation standards, do not capture the primary operational safety aspect highlighted in option C. This understanding is essential for anyone involved in electrical work to ensure compliance with safe practices and regulations.
