So, I'd have to imagine that an AHJ would legitimately fail this particular application because the wires would be stapled below the junction box and any holes in the framing may not let the join pass through. This would seem reasonable, as a stapled wire couldn't be pulled back out for inspection/repair/whatever. It talks about ".concealed and fished.", which pointed out means that the wire can't be stapled in place (ie, it has to have been fished in). ((edit, following comments.)) It turns out that the wording of the NEC is subtle and specific for a reason. I think it's generally sensible to use junction boxes, but it seems like this product would be technically permissible. Where connections to conductors are by binding-screw terminals, there shall be available as many terminals as conductors. DO NOT use filled wirenuts unless: they are intended and UL-listed for power circuits, typically a 300V or 600V listing, and, you make the splice in the appropriate junction box. Openings in such devices shall form a close fit around the outer covering of the cable, and the device shall fully enclose the part of the cable from which any part of the covering has been removed. Other methods (direct-bury filled wirenuts) are for low-voltage wiring, e.g., 24 volt lor lower irrigation valve circuits. Switch, outlet, and tap devices of insulating material shall be permitted to be used without boxes in exposed cable wiring and for rewiring in existing buildings where the cable is concealed and fished. NEC 334.40(B) Devices of Insulating Material. Insert each conductor into a splice connector and match the conductor from the other end of the cable black to black, white to white, and ground to ground. Strip the conductors on each end of the wire. Slide the heat shrink tube onto on side of the cable. NEC approved Article 334-40b.įor Use On 12 or 14 AWG (300 Volt) 2 wire NM cable with ground Strip the outer cable sheathing back about 3 inches. Splice and Tap Kits also eliminate wire nuts for installation and replace the conventional method for adding a splice or tap for non-metallic cable without the need for exposed and unsightly junction boxes. They are designed and approved for use in rework within existing structures. ![]() Tyco Electronic's Non-metallic splice and tap kits provide a fast and reliable method for splicing or tapping 2 wire w/ ground and splicing 3 wire w/ground non-metallic cables up to 300 volts. (Model # CPGI-1116377-2.) They say the following: The big box stores in the US sell something called the Tyco Electronics Romex splice kit. If I'm completely misunderstanding, please point it out, so that I and others might learn. These are readily available for RV or automotive use.I'm putting this up as an answer, mostly because there wasn't enough space in the comments. So I would be thrilled to hear that the cable actually goes from the switch to a low voltage power supply in the 12-24V range, which then powers 12-24V LED lights at the pole. Right?īecause these defects would not be of concern if this circuit were less than 30 volts and less than 55 watts. ![]() This would be a hot mess if it were mains wiring. Rigid conduit requires only 6".ĭirect burial splices are not allowed except with certain splice kits designed specifically for that. But that is not a standard and has no force of lawĬopper is not a legal conduit wiring method, so it is irrelevant and it counts as direct burial.ĭirect burial requires 24" burial depth. Several vendors are choosing to use white for NM 14, yellow for NM 12, orange for NM 10 and gray for UF of any size. UF is rated for all three.įor direct burial rating, what matters is the lettering on the cable, not the color. It is not rated for outdoor, wet locations nor direct burial. ![]() ![]() What you call "Romex" is actually NM cable.
