i work for a "Florida power and light" contractor here, so we change out meter cans and meter/mains, we also do ug services and upgrades... and from all ive done, thats just a gosh darn dirty installation there.. lol if it HAD to be done like that i would have: taken one 3" or whatever size pipe was needed to a smaller nema box sitting on one riser, and taken a pipe over to the other riser and connect it with an elbow (perhaps shorten one or both pipes..) , and either spliced in the nema box, or pull in both sets from down below.. then i would have built a uni-strut stand for it atleast.. a ghetto installation if i ever saw one.. 'woulda been ideal to come in from the bottom, and NOT penetrate the roof.. oh well!
