Guy wanted to run 6/3NM into a PVC box and wanted to use a plastic "push-in" connector. I didn't like it and said I would like to see a two-screw connector. But I had .
There are plastic push-in NM connectors made to install inside the box, such as the Raco Insider: This will install in a standard 1/2" KO. This is a very common problem, so connectors that will work with cables fished into .
Great for Outside lights when using pan boxes, it allows the box to sit very flat. I use Halex Brand. The only time they don't work well is when the thickness of the metal is too .
There's 2 14/2s coming into a 1/2" KO, the wires are already in, I can't get a regular plastic romex connector around them. The inspector told me they make one that goes on from . The junction box (includes transformer on one side) is plastic and has knock outs for clamps of the in/out wires. I would like to use my metal clamps but, since the box/fixture has no ground and I am adding metal, I am not sure .

They work nicely in a new panel installation. But if it's a panel change out with no sheetrock-cutting allowed I prefer the connectors with locknuts. I also use the plastic assholes . The problem is that you should use a connector in the box. A button connector won't work since the 1/2" KO in the box is threaded. A typical metal 2-screw romex squeeze connector works, but it requires a 1-1/2" hole in the .
Entering with a metal raceway could work if the raceway is bonded elsewhere, but your connector is pretty isolated and will not pick up any bonding elsewhere. You could install . Using Plastic Push-In Connectors The newcomer on the block is the plastic push-in connector. There are several different designs for these, but basically, they are all plastic bushings that snap into the knockout hole in the metal box. Guy wanted to run 6/3NM into a PVC box and wanted to use a plastic "push-in" connector. I didn't like it and said I would like to see a two-screw connector. But I had questioned whether it would have to be bonded. There are plastic push-in NM connectors made to install inside the box, such as the Raco Insider: This will install in a standard 1/2" KO. This is a very common problem, so connectors that will work with cables fished into boxes are available almost everywhere electrical supplies are sold.
Great for Outside lights when using pan boxes, it allows the box to sit very flat. I use Halex Brand. The only time they don't work well is when the thickness of the metal is too thick for it to sit properly. There's 2 14/2s coming into a 1/2" KO, the wires are already in, I can't get a regular plastic romex connector around them. The inspector told me they make one that goes on from the inside over the existing wires, but I've never seen it. The regular plastic "push-in" rom conn probably won't work. The correct thing to use is not a grommet, but a NM clamp, as the latter grabs the cable's jacket and strain-relieves it to the box. They are available in a few different types (some are metal, others are plastic), and install into a standard 1/2" knockout, either using a locknut (for metal and some plastic types), or simply by snapping into . The junction box (includes transformer on one side) is plastic and has knock outs for clamps of the in/out wires. I would like to use my metal clamps but, since the box/fixture has no ground and I am adding metal, I am not sure if this is allowed by code.

I often use a small flat screwdriver and give it a whack. They work nicely in a new panel installation. But if it's a panel change out with no sheetrock-cutting allowed I prefer the connectors with locknuts. I also use the plastic assholes (the little button-type ones) if I need a lower profile bushing. The problem is that you should use a connector in the box. A button connector won't work since the 1/2" KO in the box is threaded. A typical metal 2-screw romex squeeze connector works, but it requires a 1-1/2" hole in the brick to accommodate it's size.
