I’d like to make it flush. The backside of the wall is completely exposed so I have a wide array of options I could choose. Is a 4-11/16” box the same thing as an “11-B” box that people talk about? I could just do that like you said. I just wasn’t sure if I was being extra of using a standard 4 square box would be plenty.
I’m sorry I didn’t know there was a difference between plug and receptacle. I am speaking about a standard receptacle you plug a range into. Thank you for the suggestion I’ll look into this. I have an exposed studded wall behind the wall I want the receptacle to be on so I’m wondering if it would be fine to just slide this metal bracket piece in between the stud and drywall and throw a screw into the other holes for the bracket.
Outside of volume of the box issues, some receptacles may or may not accept 4 AWG, some may or may not accept aluminum conductors. I'd guess those that do accept aluminum probably will accept #4 though.
Yes, if you back up the box on the bracket and flatten the tabs, it should tap in. You could also remove the bracket and mount the box to a stud with a couple of screws, but that's not really considered Kosher.
Certainly.
I believe the cubic inch calculations only go up to #6, after that you start to need to go by raceway size or "equivalent" raceway needed and the 6x or 8x raceway size rules. 4 AWG in this case won't be anything smaller than 1 inch raceway, so that means the box needs to be at least 6 inches in one dimension, and at least wide and deep enough to house the receptacle.
If a minimum of 6 inch dimension is needed on the box you may not have enough wall depth for 4x4 box and however many extensions are needed though.
The homeowner won’t provide me with a range to base my wire size and amperage so I’m running a 50 A circuit for 2 units. One unit is about 25-30 ft away and the other is about 15-20 ft away. To give an example of my options, Home Depot had 4-4-4-6 AL SER cable going for $1.14 per foot. I know that’s overkill but it’s cheaper than other cables with lower ampacity. And considering the 30ft pull is through the attic I wasn’t sure if I needed to apply the rule where SE cable in insulation being taken at 60 degree C but 4 AWG Al is still good for 55 A. That’s what I planned on using but now they’re sold out. 6/3 CU romex is 6.73$ per foot. I found 6-6-6-8 AL MC cable for 140$ woke up the next day and it’s $250. It’s hard to coordinate buying this and getting the homeowner to give the OK before the cable is out of stock and too expensive. My next option is to look at running conduit but I’m sure with everything it would be the same as just buying romex.
No I have a duplex each w their own range . I planned on buying a 50ft roll and using 30ft upstairs and 20 ft downstairs .
