Expert Analysis

In the 2011 NEC development process, Section 210.8 was revised to require the GFCI receptacles required by 210.8(A) through (C) be readily accessible. GFCI receptacles installed on rooftops in accordance with 210.8(B)(3) and 210.63 could be considered as not readily accessible by definition, subject to interpretation.  Information in the substantiation indicated that unless rooftop(s) on a building, other than a dwelling unit(s), is provided with a permanent ladder for rooftop access, GFCI receptacle(s) installed on the rooftop do not necessarily meet the readily accessible requirement as written. The exception provides practical relief from the readily accessible requirement while maintaining the ready access to the GFCI device from rooftop locations where it is most likely necessary, such as for rooftop service personnel.
