What is the maximum height above the floor for the operating handle of switches or circuit breakers?

The maximum height above the floor for the operating handle of switches or circuit breakers is 6 feet, 7 inches. This standard is set to ensure that electrical equipment remains accessible for operation, maintenance, and safety checks.

In residential and commercial settings, this height allows most individuals to reach the controls without the need for ladders or other assistance. This accessibility is crucial for emergency situations where quick access to shut off power may be necessary.

Understanding these regulations is vital for electrical contractors, as they help ensure compliance with the National Electrical Code (NEC) and promote safety in electrical work. The other options exceed this height, making them non-compliant with these accessibility standards.
