Expert Analysis

A revision has been made pertaining to receptacles in

damp or wet locations to require hinged covers of outlet

box hoods to be installed to allow the cover to open to

either 90 degrees, or fully open depending on

cover type. The signiﬁcance is that the covers swing

can't be blocked by any obstruction.
