Single Product Review: Madison new/old work boxes Discussion: These boxes are the best for outlets/electrical boxes which require structural strength. As these were going to house outlets, which I planned on plugging/unplugging often, I wanted extra strenth, especially the 2-gang holding both the twist lock plug (NEMA L5-15P), and a switch. These were easy to mount, using the included screws. Cut the dry wall a little on the tigher side, so that it will hold the box in place as it is screwed to the wall stud. Project Summary: I have a temporary solar/PV battery backup project in the garage, and I wanted to use the generated solar power inside the house. Previously has an extension cord running through the door to the garage, but that's not safe for a lot of reasons, so I wired up a couple of electrical boxes, and wired in a cut-out switch. The inside connections are a standard wall outlet, and the outside connection to the inverter is via a twist lock plug, for extra security. Project Recommendations: 1) I looked at a lot of generator inlet receptacles, but most were 20-30 amp, and I don't need that large (standard 15A), so I used a NEMA locking L5-15P instead. 2) As this was going to be a twist lock plug, I wanted to attach the electrical box to a stud if at all possible (vs. using the electrical box which clamps onto dry-wall). The Madison Electric Products boxes were perfect. I used a single gang on the inside box, and for the outside, I used a 2-gang so that I could also fit a cut-off switch. I mounted the 2-gang box rotated 90 degrees to the normal orientation for two reasons: a) I could screw it directly into the horitzontal stud, and b) I could mount the plug on the bottom, and the switch on the top. 3) When it comes to electrical parts, I generally go with Leviton, which I have had great success with. The only item I got that was a different brand was the right angle plug (which Leviton also offers, I just didn't see it when placing the order, otherwise I would have ordered that one instead). Conclusion: All the products listed in the review, and used for this project I am rating 5-stars.
