Is it necessary for electrical disconnects to have a visible indicator for their operating position?

Only for commercial applications
Yes, it's mandated by the NEC
No, unless specified for high voltage systems
It depends on local regulations

The correct answer is: Yes, it's mandated by the NEC

Having a visible indicator for the operating position of electrical disconnects is indeed mandated by the National Electrical Code (NEC). This requirement is in place to enhance safety by ensuring that anyone working on or around the electrical system can easily determine whether a disconnect is in the "on" or "off" position. Visibility reduces the risk of accidents, as it helps to prevent an individual from inadvertently working on an energized circuit, which could lead to electric shock or other serious injuries. The NEC aims to establish standardized practices that promote safety and reliability across various electrical installations, making compliance crucial for all types of applications, not just commercial or high voltage scenarios.
