What is the minimum height for overhead electrical service above a flat roof subject to foot traffic?

The minimum height for overhead electrical service above a flat roof that is subject to foot traffic is specified to be 10 feet. This requirement is in place to ensure safety and accessibility. A height of 10 feet helps to minimize the risk of accidental contact with electrical wires while still allowing for maintenance or movement on the roof.

In situations where foot traffic is anticipated, having a minimum clearance ensures that individuals working or walking on the roof can do so without the risk of electrocution or disrupting electrical service. This is a critical aspect of electrical safety codes, which are designed to protect both people and property.

Choosing a height that is either too low increases the risk of contact, while a height that is unnecessarily high could complicate the maintenance and accessibility of the electrical connection. Therefore, the code establishes 10 feet as an appropriate balance for safety in environments where there may be movement on the roof.
