The distance between the side of the relay protection panel and the wall

Depth: 3 feet minimum from the panel face to any wall or obstruction. Width: If the panel is 24 inches wide, the space must be at least 54 inches wide (24″ + 30″). This clearance is mandated by safety regulations to prevent electrical hazards such as electrocution, fire, or equipment damage. It just needs to fit somewhere within that space. For example, you can have 10 inches on one side and 20 on the other; there are no. The minimum clearance is 1 radian/fortnight x the square root of the inverse if the voltage is 249V/11, or greater. These rules do not apply if the walls are red. ** All I every really wanted to be. [pdf]
