Can someone please put OEC rule #12-3036(3) in to english for me? It all makes sence about the part where the useable space shall be reduced by that of the device, but the confusing part is just after that. Where are they coming up with these numbers? 82cm3??? the example did nothing to clear up the rule for me..... I just want to know what boxes to use when installing GFCI's. in an industrial atmosphere, ie. FS boxes 1110 ...
