Hello Having more electrical outlets is always good. Just plugging in a power strip works but is cumbersome. So when I saw the ac outlet with 2 USB outlets, that would be nice to have? Why take out a a good gfci outlet to put this one in? So I got a double gang box to add this one in. so why not remove the single gang new workbox and install a double gang old work box? I have done this before and just cut the nails with the Sawzall? Well this new workbox was a vapor box with the flange around it to keep out the draft! What draft is there in a new construction fully insulated 2x6 wall with reflectix foil? Anyway, I cut some of the flange off with the sawzall and pulled one of the nails out and pryed it off the stud then got it out of the wall bit still broke off too much of the wall to hold the new box ! Now what? My electrical buddy said battleship or Madison. I said not in the mood for playing games and don’t call me Madison! She said those are the fingers you need now to hold it in! Wow these are cool! Anyone else have these darn difficulties?
