Jerry Simon Posted May 30, 2022 Report Share Posted May 30, 2022 30" to the side or sides of the panelboard (not sure of exact language; apparently I should be). From the sides of the panelboard cabinet? From the side edges of the deadfront cover? Quote Link to comment Share on other sites More sharing options...
Marc Posted May 30, 2022 Report Share Posted May 30, 2022 Simply a clear space 30 inches wide. Panel can be anywhere within that space. 1 Quote Link to comment Share on other sites More sharing options...

Never thought about it until I ran across one that had the main breaker at 84in from the floor! Quote Link to comment Share on other sites More sharing options...

Most people don't realize there is also a height requirement as well. Never thought about it until I ran across one that had the main breaker at 84in from the floor! It's a little more complicated than that. 110.26(A)(3) says that the maximum height is 6'-6" *or* the height of the equipment, whichever is greater. Lots of panels extend higher than 6'-6" and their working space should be just as high as they are. Under this rule, your 84-inch-high breaker would require clear working space around it. But the 2nd exception after this rule confuses matters. It allows the working space to be shorter for equipment 200-amps or less in "existing dwellings." (While it doesn't explain "existing dwellings", it means before this rule came into effect - pre-1993.) They specifically did not want the rule to apply to pre-existing panels. As for the 84" high breaker, two separate rules restrict that. 240.24(A) and 404.8 both limit the height of breaker handles to 6'-7" in their highest position. It's interesting to see that both the working-space rule and the breaker-height rules are 2 meters, but the working space rule resolves that to 6'-6" while the breaker-height rule resolves it to 6'-7". . . Two different committees, two different translations from metric. 1 Quote Link to comment Share on other sites More sharing options...
