Question:

Hi Charlie, per our county electrical code I am required to install an emergency shutoff for a 200A single-family residential service. The county electrical code specifies the shutoff must be installed within sight/30ft of the wall of the structure and labeled clearly. The service pole and meter are in direct line of sight but measure 39ft from the nearest wall of the residence. Power comes in overhead and then goes underground to the residence.  I want to install the emergency shutoff on the service-pole the inspector wants it on a pedestal within 30 ft. What does the NEC® require for this emergency service disconnect? I am hoping I can provide some evidence that will change this inspectors mind. My objections being added expense and aesthetics, and arguments being that installation on the pole satisfies the codes intent and puts the shutoff where it will be most easily located by emergency responders. Regards, Michael B.

Answer:

Hello Michael, thanks for participating in the CQD. Unfortunately, we are not able to provide insight on your County Electrical Code requirements, or on how to change the inspector’s mind. As for the requirements in the NEC®, Section 230.85(A)(1) require that the service emergency disconnecting means be installed in a readily accessible outdoor location on or within sight of the dwelling unit it serves. NEW Section 110.29 explains that “Within sight from/of” means the one piece of equipment is visible from the other piece of equipment and not more than 50ft away.
