Then slide the Romex connector into place and take your screw driver and tighten down the lock nut through that slot you cut in the drywall that will still be covered by the panel cover when it is installed. Electrical code wire wiring electrical codes romex.

Then slide the cable through that lock nut through that panel box knock out and then throught the Romex connector. Thanks for visiting our website, did you know that Phase 3 Connectors USA is on. Take a screw driver and slide the lock nut of the metal Romex connector into place on the outside of the panel box. You have about an 3/4" to play with that the panel cover will still cover. You also can do as discribed in the previous replies only cut a slot in the drywall above the panel box that will still be covered by the panel cover. When the nonmetallic connector snaps into place it also grips the cable and holds that cable in place. Then grasp the nonmetallic connector and pop it back into the panel box knock out from the inside of the panel out. You can fish your Romex into the panel, then slide the nonmetallic Romex connector over the cable into position on the wire just before it goes out of the panel box knock out hole. This nonmetallic Romex connector is a one piece unit that will slide over the cable the pop into the knock out. Conductor insulation is 90☌-rated polyvinyl chloride (PVC), nylon jacketed. Stranded conductors are compressed stranded. Copper conductors are annealed (soft) copper. I do not believe I used too much force when securing the wires but obviously the pictures say otherwise.There is a very inexpensive non metallic Romex connector that you can buy at most electrical supply houses. Southwire Romex® Brand SIMpull® NM-B cable is manufactured as 2, 3, or 4 conductor cable, with a bare ground wire.

At this point I removed the cable from the sub-panel also and found signs of sheathing damage there also, as per attached photos. When I initially tightened the connector on the cable I did not crank it down excessively but obviously enough that it compromised the thin outter sheathing and caused a direct short between the black insulated conductor and the connector screw/pad. I soon found the culprit, a short right where the 10/3 cable passes through the throat of the cable connector. I shut off the main power again to try and figure what the problem was. Main breaker on and all is well until I set my new 30amp breaker and then flash! Instant short circuit with a good spark that instantly got my attention. Southwire 63948426 10/3 100 Orange with Ground Romex Brand SIMpull Residential Indoor Electrical Wire Type NM. I double-checked all my connections to ensure all was well before restoring power to main panel. At the sub-panel I used another metal box connector to secure the cable.

I ran the 10/3 cable to my Stablok main panel, using a 3/8 metal box connector to secure same as seen in photos below. For now I'm only adding a few 15amp circuits (120V) only and 30amps is plenty for now. I'm installing a Siemens 100amp/8 circuit sub-panel but only feeding it with a 30amp double-pole breaker and orange, 10/3 NMD90 cable. I just had an experience today involving shorting of 10/3 romex cable where it passes through the throat of a typical 3/8 NM cable/box connector and would wish to share same with readers for their comments.
