Please note: Since creating this question, several community members have explained to me that since I'm running 12/2 and 10/3 I will have a grounding wire and so the electrification concern I mentioned below in the question is null and void. However I really don't like the look of metal (remember these outlets will be fully exposed and tapconned to basement walls) and would prefer the look of PVC, but that is only aesthetic. If it is near impossible to find a PVC solution and super easy to find a metal-based solution, I will totally accept the metal solution and would consider just painting the metal a color of my choosing.
Background context and project specs
I am planning out the installation of 3 new outlets in my basement. I have a buddy that will actually install the breakers and do the wiring in the electrical panel (he is a licensed electrician) but I want to take on:
- Installing the junction boxes
- Running the (Romex) cable from the area where my service panel is (remember: I'm not doing the live electrical hookup) to the junction boxes, including running the cable through protective sleeves (I'll explain in a minute)
- Connecting the cable to the outlets
- Fastening the outlets into the junction boxes and attaching faceplate/covers to them
So I would do all the "outlet-end" work and my buddy will do all the "panel-end" work (the actual hookup). And yes, he will absolutely verify I did everything correctly before he turns anything on. The point of this exercise is to get me more familiar with doing light electrical work around the house, while doing it safely and in a controlled manner.
So, these outlets will be several feet off the ground and the junction boxes must attach to the concrete block foundation of my basement walls. The junctions must contain a knockout on the top of them so I can run the Romex cable into them from the top (this is more aesthetic for me than anything else). I want the Romex cable encased in a conduit to act as a protective sleeve (and nothing more) and I want that conduit to run from the top of the outlet all the way up to the "ceiling" of my basement which contains open-faced floor joists (that hold up the 1st story of my house). At that point, the conduit/protective sleeve would end, and the Romex cable will run along the bottom of my floor joists and attached/secured to them by staples. I obviously need to leave several feet coiled up once I get to the service panel, to give my buddy plenty of wiggle room to make his connections.
Further, I am really not a huge fan of metal junction boxes and metal conduit. I'm not a fan of how they look and whether its uneducated or not, they just sort of freak me out and make me worry about whether they could ever become electrified in the event of a fault. If you tell me metal is the only way I can go here, I would of course use them, but I would appreciate an explanation of why so that I can understand. Otherwise, I'm looking to go with PVC junction boxes, PVC outlet covers and PVC conduit/protective sleeves.
So here are my 3 outlets. We have a NEMA 14-30 240V 30A outlet that will be getting a (240v) GFCI breaker at the panel. Then we have two (2) 3-pronged duplex outlets (20A 125VAC). One of them is a GFCI outlet and one of them has a pair of USB chargers in it. I will be running 12/2 Romex NM-B to both duplexes and 10/3 Romex NM-B to the NEMA. The Romex must fit inside the 1/2" conduit protective sleeves (please speak up if thats not possible!!!) It is important to note that all 3 outlets will be at different locations in the basement and will not be sharing cables, conduit or junction boxes. They are all fully independent. Without further ado:
What I've done so far
I am trying to purchase junction boxes, outlet covers, conduit and conduit-to-junction connectors for each of these 3 outlets and I'm having a tough time finding products that will get the job done given all my constraints. I have found two products off of a bigbox retailer website:
The junction box I found seems to meet all my needs:
- made out of PVC
- looks like I can attach it to my basement walls with tapcon screws
- looks like it will fit all 3 outlets (though the wider NEMA 14-30 might be a tight fit...)
- has knockouts on the top for the protective sleeve conduit
- I have a long section of 1/2" PVC conduit and it appears I can run the Romex through it and connect the conduit to the box with some type of connector
- looks like it has screw holes that would be compatible with all 3 outlets (for fastening them to the junction box)
The cover I found for the 2 duplexes also seems to check all the boxes as well:
- made out of PVC
- seems to fit the junction box above
- seems compatible with both duplex outlets
The only straggler that I wasn't able to find a product for is the faceplate/cover for the NEMA 14-30 junction box/outlet, and I would appreciate any suggestions.
My actual question
Will the products I've listed above work for my needs (given all the constraints/specs), and if not, why and what products would work instead?
