If obstacles would make it unsafe for you to inspect the service panel, you have the right to disclaim it. This assures that in case of an electrical emergency, there is a clear work- ing space in front for quick access to the circuit breakers. This space requirement creates sufficient room for you to work on the equipment without contacting live parts and metal parts. Every electrical equipment installation must be evaluated, and where possible, the proper clearances should be provided. The clearance is 36" in front and 30" side-to-side -- but that side-to-side clearance does not have to be centered on the panel as long as both edges are accessible.
