What is the required clearance depth in front of power panels?

The required clearance depth in front of power panels is 36 inches. This standard is essential for ensuring safety and accessibility for maintenance and operation purposes. The 36-inch clearance allows adequate space for personnel to safely operate the panel, perform maintenance, and access electrical components without restriction or danger.

In terms of safety regulations, adhering to this clearance depth minimizes risks associated with electrical hazards, such as arc flash or equipment malfunction. Moreover, this distance helps ensure that there is sufficient room for tools, ladders, or other equipment that may be necessary during maintenance or inspection of the power panels. Having this level of clearance also complies with industry codes, such as the National Electrical Code (NEC), which emphasizes maintaining proper working spaces around electrical equipment to promote safe environments in commercial and residential settings.
