What is the maximum height above grade for a pole supporting a luminaire that doesn’t require a handhole?

The maximum height above grade for a pole supporting a luminaire that doesn’t require a handhole is 8 feet. This specification is often derived from safety and accessibility standards, as poles that exceed this height typically necessitate additional features for maintenance and operational access, such as handholes.

When luminaires are installed at heights up to 8 feet, they remain within a range that allows for easier maintenance and service without requiring specialized equipment like lifting devices. This is especially important in outdoor settings where accessibility is a concern for maintenance personnel. Poles exceeding this height would complicate the maintenance process, hence the need for a handhole to facilitate access.

The choice of 8 feet as the threshold reflects practical considerations in electrical installations, especially in residential or commercial areas where maintenance efficiency and safety are primary concerns. Understanding these regulations is crucial for ensuring compliance with local codes and enhancing the longevity of the installation.
