I am having new galvanized steel ductwork installed in my attic, replacing the old flex duct that was there. What is the correct gauge sheet metal that should be used? The contractor says he will use 26 gauge for supply and return trunks, and 30 gauge for branch runs?
What is the best way to transition from THHN wiring in exposed conduit to a wall panel inside a wall? The conduit holds wiring for a 120v circuit and a 240v circuit with power outlets. I was going to use a 4x4 junction box to .Put a box to transition from the EMT to the flex with the proper connectors. Cut a piece of wood, mount that to the concrete wall, and use a one hole strap to secure that EMT between the boxes. No bender needed and room to run . 300.15 Boxes, Conduit Bodies, or Fittings — Where Required. A box shall be installed at each outlet and switch point for concealed knob-and-tube wiring.

Conduit (RNC) to 1/2" Liquidtight Flexible Nonmetallic Conduct (LFNC) and 2) you need to make a connection from RNC to LFNC. The cleanest way to do this is to have your 1" RNC terminate . (To clarify on the details, there is little junction box you can get that attaches to the end of this transformer. I was considering running the conduit from that to the wall. Is that even .
Then transition to a cable like Romex and use a junction box to splice the conductors. I fully understand the NM and Conduit rules and had planned to transition from 6/2 NM-WG to 3x#6 THHN (conduit) at the exterior wall in a junction box. Then I saw NM wire . I'm thinking of running THHNs all the way from the receptacles to the main panel to minimize any splicing at the Junction/Pull box. The challenge is the transition spot between .
You can use user-supplied cable or conduit from the outlet box to the EVSE. Starting from the outlet you can use either a box extender or plate with a knockout to transition . The poorly drawn image below illustrates what I was thinking of doing. Is this ok or would it be better to bend the conduit or use a 90 degree over the corner and use a straight connector to join the pvc to the liquid tight .
300.15(F) only excludes two conditions. The section as a whole has several conditions that require a box or body. No box or body is required because we do not have: conductor splice point, conductor outlet point, .Do you have to put a junction box at the emt entrance point and transition from Romex to stranded? That's stupid and I don't like it. Share Add a Comment. Sort by: Best . You can use a 1/2” C-style conduit body instead of the junction box, it’s a cleaner looking transition. Plus, the volume in the conduit body would allow for your splicing. It is not class 2 on either side. I need to mount it on the wall in a finished room because it's far from any unfinished space. How do I properly get the output side wire (the side that is going to run to some LEDs) back into the wall (where it will then run to the junction box to which the lights are connected)? Thanks.
"90% of the time when Carflex (LFNC) switches over from a LFNC to a PVC or Fiberglass conduit it will terminate into a junction box. LFNC Fittings has to be used with LFNC per the NEC. It is allowed to use a LFNC Fitting with a PVC Female Fitting. The PVC fitting would solvent cement to the PVC conduit and the LFNC fitting would screw into it." Nipple between the LB and the old work box. Drop your flex down into the top of the old work box. If you penetrate the ext wall behind the surface mount panel, you don't really have any way to seal your penetration on the outside of the wall. Reactions: JJWalecka. S. Solar_ice_caps Member. Location Florida OccupationWhat kind of junction box do I need on the indoor side of the wall? I'm not finding one that accepts both NM clamps and glue/threaded connections. I assume I can't just stub the conduit through the wall, feed the NM to it, and then staple it to the stud? It just seems like it would be better to use a junction box on both sides of the wall.
I originally had the NM-B cable entering the knockouts located in back of the box. After posting my last question here, it seems I need to transition to THWN wire before entering the box. Please correct me if I am wrong. I do not want any junction boxes in my living area. So I have several methods in mind to run wires to my box, Method 1 Use appropriate methods to transition between conduit types (e.g. transitioning via a junction box). Adhere to conduit fill rules for both types of conduit. You may need to up-size the trade size for flexible conduit relative to rigid conduit . If the armored cable is BX without a copper ground, use a metal junction box and attach the Romex grounds to the metal box preferably with a ground screw and pigtail (stinger). Reactions: FirstHomeMKE. Save Share Reply Quote Like. J. Jim Port. 21099 posts From there I will run the Romex into a junction box. Inside the junction box I will strip off the outer Romex, exposing the 3 THHN wires inside of it (hot, neutral and ground). The hot and neutral wires will not be perturbed at all and will be sent down a PVC conduit all the way to the junction box housing the outlet, where they will be .
I am hooking up some industrial screw press machines that need to be feed from a junction box above the equipment. I know article 400.12(1) says flexible cord cannot be used for fixed wiring, but the second sentence in article 430.6 says “Where flexible cord is used, the size of the conductor shall be selected in accordance with 400.5”. Does this mean that I can run .
Measure your flexible conduit against your existing wiring, and mark up the place where you’ll need to cut it at. Use a pair of wire cutters or a hacksaw to cut the PVC. Step 3: Insert the Flex into Your Junction Box. Slide your flexible conduit into your junction box, making sure that it’s all the way in. Rather than trying to run the cable out exposed and then into the bottom of the box, or try to clamp it when it's going into the back, I'd put an ordinary 2½" deep, "5S" (really just under 4¾") square metal junction box on the inside back-to-back with the disconnect, then use a nipple with sealing locknuts to connect the JB to the disconnect .
I was going to use a 4x4 junction box to transition through the back of the box into the wall using using romex behind the wall. . or equivalent for a 4" square box) on the box. Or, use an extension. If the flex whip isn't . Run / attach the conduit to a junction box, and then put a clamp for the romex, not a problem. You should to run a green ground wire in the conduit along with the hot and neutral so the romex has a nice solid ground. .For prewiring the wire is landed into an junction box / outlet, IE homomorphic to the unused receptacle that you have right now. . Starting from the outlet you can use either a box extender or plate with a knockout to transition to surface .

NOTE: If you are installing Flex with a Walltrac Accessory, see page 05 for installation information. TIP! Make sure to coordinate the opening with your furniture 1 2 IN-WALL ENTRANCE FITTING CONDUIT TO JUNCTION BOX Use the metal-collared openings on both sides to fasten plastic base to floor AConduit is already there (has been for 90 years). I’m trying to replace the existing wire with THHN and I practically can’t terminate a conduit with a junction box. As a result, if I ran THHN in the conduit, I couldn’t come out of the conduit into a junction box. . With the flex conduit securely attached to the junction box, you are now ready to move on to the next step: securing the flex conduit and junction box connection. Step 6: Secure the Flex Conduit and Junction Box Connection. Securing the flex conduit and junction box connection is crucial for a safe and reliable electrical installation.
Rigid parts give us the flexibility we need. While flexible conduit seems like an attractive option for making the "around the horn" bend behind the drywall, it doesn't work so well due to the issue that flexible conduit fittings are designed to work with junction boxes, not conduit bodies with their built-in conduit hubs, or any other sort of hub fitting for that matter.
Because the platform is detachable, the wiring runs through a junction box, and if the platform needs to be detached, I kill the breaker, open the junction box, and disconnect the wires from the wire nuts. . The romex is currently in watertight flex conduit, except at the junction box where the main line connects to the platform. Thank you . Would it be possible to run the existing flexible conduit into my new wall and into a metal junction box at the top of the wall so that it ends up being towards the top of the wall. could I then run romex out of this box and into the plastic switch and outlet boxes that I'll be using further down the wall but facing the other direction in the . Uh oh. So, the lack of a backing nut would disqualify it? I'm not sure what other type of box would be useful with flex conduit. A standard gang box doesn't seem like it would be water-tight enough for outdoor use. Alternatively, what kind of conduit would be used with the box that I've shown? I thought flex would be a natural fit. There are 3 strings in series any junction box on the roof would transition from PV wire to THHN, into the structure and through individual DC disconnects. Two of the arrays will be paralleled at input 1 of the inverter, EG4 18K.
You can transition wiring methods at a junction box. Use the EMT wiring method up to the junction box (whole nine yards with fittings and clamps). Then use the NM wiring method beyond it. The junction box must remain accessible without screws, nails or demolition (other than the ones on the junction box lid, of course). Any cost savings using thwn versus use2. My authority having jursid told me he didn't like me running use-2 all the way from PVs to Inverter but must provide a junction box to plug my MC4 connectors from the PV panels into, then transition at that point to thwn-2 which would stuff into a 3/4 EMT conduit to run down the wall to my inverter.
