Code Watch: The 3-Foot Rule

Think of the space in front of your electrical panel as a “no-fly zone.” We’re breaking down the required clearances to keep your home safe and compliant with local code.

A residential electrical service panel with the required three feet of clear working space around it to meet NEC safety standards.

The 3-Foot Rule

The National Electrical Code (NEC) mandates a specific “working space” around electrical equipment. This is often referred to as the 3-foot rule.

The Impact: For most residential panels, you are required to have a clear space that is 3 feet deep, 30 inches wide, and 6.5 feet high. This isn’t just about making my job easier when I come to service your home; it’s a critical safety measure. In an emergency, you (or a first responder) need to be able to reach those breakers instantly without tripping over a lawnmower or digging through holiday decorations.

If you’re planning a garage shelving project or just cleaning up, make sure your panel has its “breathing room.” It keeps you compliant with Huntsville codes and ensures your home stays safe.
