Tim Maxwell Posted February 22, 2014 Report Posted February 22, 2014 Yesterday I had an exterior main disconnect at the exterior by the meter. The 150 amp main was over 80" above grade. Would this be under the 240 section in NEC regarding the 6'-7" rule? I'm 5'-12" and I could reach it, but anyone much shorter would need a bucket or ladder to reach it.
Erby Posted February 22, 2014 Report Posted February 22, 2014 Sounds like it's an inch over. Probably due to soil settlement after construction. Tell them to throw down some more dirt and be done with it.

Jerry Simon Posted February 23, 2014 Report Posted February 23, 2014 I'm 5'-12" Is that a regional thing (versus being 6')?
Jack Davenport Posted February 23, 2014 Report Posted February 23, 2014 Here is the code section from the 2011 NEC 240.24 Location in or on Premises. (A) Accessibility. Overcurrent devices shall be readily accessible and shall be installed so that the center of the grip of the operating handle of the switch or circuit breaker, when in its highest position, is not more than 2.0 m (6 ft 7 in.) above the floor or working platform, unless one of the following applies: (1) For busways, as provided in 368.17©. (2) For supplementary overcurrent protection, as described in 240.10. (3) For overcurrent devices, as described in 225.40 and 230.92. (4) For overcurrent devices adjacent to utilization equipment that they supply, access shall be permitted to be by portable means.
Tim Maxwell Posted February 23, 2014 Author Report Posted February 23, 2014 I'm 5'-12" Is that a regional thing (versus being 6')? just a joke, and see if anyone noticed.
ghentjr Posted February 23, 2014 Report Posted February 23, 2014 Yes, some of us did, and we also noticed that the exterior main disconnect was on the exterior.
Jim Baird Posted February 24, 2014 Report Posted February 24, 2014 "...I'm 5'-12"..." Down here they just say six feet. Reminds me of what a plumber once told me, "Anything smaller than a quarter we just call a half." Should not that disco be contained inside "working clearance" that maxes out a six ft six?
Marc Posted February 24, 2014 Report Posted February 24, 2014 ... Should not that disco be contained inside "working clearance" that maxes out a six ft six? Wouldn't that be putting the cart ahead of the horse? Clearances follow the enclosure, not vice versa. Marc
Jim Baird Posted February 24, 2014 Report Posted February 24, 2014 I guess you could build a ramp or steps and landing to get there. ...

Jack Davenport Posted February 24, 2014 Report Posted February 24, 2014 "...I'm 5'-12"..." Should not that disco be contained inside "working clearance" that maxes out a six ft six? Actually the height of working space is 6'6" OR the height of the equipment whichever is greater.
