An overcurrent protection device must be installed such that its operating handle is a maximum of how many inches above the floor?

An overcurrent protection device must be installed so that its operating handle is a maximum of 120 inches above the floor. This requirement ensures that the device is accessible for operation and maintenance. In residential and commercial settings, it is crucial to have overcurrent protection devices, such as circuit breakers, positioned within this height range to allow for safety and convenience during use.

The 120-inch maximum height aligns with accessibility standards that prioritize safe and easy access for individuals to operate and reset breakers as needed. Ensuring that these devices are not too high can help prevent accidental issues, such as difficulty in reaching the device during emergencies, which is critical for overall safety in electrical installations.

This height limitation promotes compliance with safety codes and regulations that govern electrical installations, reflecting the need for prudent and accessible equipment placement in buildings.
