I was working at house today for a GC,Gc tells me run power for disconnect out of ledger board under the deck and mount disconnect in between joist spaces on deck and but to top of ledger board and bottom of deck boards.I inform the gc that with the blocking that's installed that you you cant put it there you need to be able to open the Disconnect all the way not just 60 degrees . Gc says do what you can get as close as possible . GC leaves get to the point of drilling hole and Homeowner comes home says "what are you doing",I say "mounting A/C disconnect". He informs it was supposed to be thru ledger board and tight to bottom of deck . He storms off calls Gc and reams him anew one .I overhear him say I don't need guy's making 12k a year making decisions on my project without my say so .I heard that and just about threw my tools down and went and had a talk with MR H.O. . But kept my cool and after about 10 minutes of explaining the situation he understood why I had to do it. This guy is a white collar guy for sure,but I find the lack of respect for our trade kind of demeaning.Just had to vent sometimes douche bags get to me.
