These sound great since they are good up to 20 AMP when one needs another receptacle like we could use in the electrical bin. No thanks, I'll continue to make wire splices the tried and true method - per my state's electrical code. I would expect those you speak of to be the same. The 12VDC in-line wire taps are junk, they cause ever so many problems.(ever had electric brake problems?) Under high current draw they have high resistance in the tiny contact area. The NEC does not approve anything and I saw no reference to UL which has the approval authority, bee careful. If it works like the 12v connectors, a pair of pliers should do it. JohnI don't recall any tools being mentioned on the outside of the package. Any info on what tools you heed to put it on? They should solve a lot of problems in RV electrical work. The connectors made by AMP and can be found in the electrical department at Ace Hardware and no doubt, other stores as well. It is NEC approved and it eliminates the need for a junction box. There is now available a connector which allows you to splice into an existing 12 or 14 gauge Romex cable without cutting the insulation or the wire. 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.RV.Net Open Roads Forum: Tech Issues: Splicing 120v (Romex) Wire - FYI Open Roads Forum 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. 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. 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. NEC approved Article 334-40b.įor Use On 12 or 14 AWG (300 Volt) 2 wire NM cable with ground 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. I'm putting this up as an answer, mostly because there wasn't enough space in the comments.
