I have seen those combo disconnects before but when I looked I was not satisfied with the internals, some I have seen do not have breakers dropping down the current for the outlet.
Every time I have used the tap rules I get in trouble so I avoid them and use a plane old disconnect and and a GFCI in another WP box.
