Tyco Splice Kits


I discovered the Tyco Electronics Romex Splice Kit at Home Depot:

http://www.homedepot.com/h_d1/N-5yc1...&storeId=10051

The description says NEC approved for splicing two wires without a junction box. Does anyone know if this is true? Can I use this splice kit and then cover over it with drywall without an accessible junction box? Will the inspector pass me if I use this? I know general policy is all splices must be done at junction boxes, and all junction boxes must be accessible.

And FYI, I do NOT live in a mobile home. When I tried to google the answer to this question I came up a lot of results that mention this product is commonly used in mobile homes. I don't really know how that changes things, but let's keep this thread focused on what is approved for single family/townhouse/apartments.

The NEC still requires all splices to be accessible.

Maybe I was wrong. But I still say I would not want hidden splices in my walls.

(B) Devices of Insulating Material. 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.
Openings in such devices shall form a close fit around the
outer covering of the cable, and the device shall fully en-
close the part of the cable from which any part of the cover-
ing has been removed. Where connections to conductors are
by binding-screw terminals, there shall be available as many
terminals as conductors.

I don't totally understand your post. Does the NEC allow for these types of splices to be hidden by drywall or not? At first you're saying no, then you seem to indicate yes but you wouldn't.


If this splice must still be accessible, then I don't really see the point of this product. Again, I don't know how accurate the product's claims are, but it's definitely claiming that it can be hidden. From the Home Depot product description: "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."

I would not trust it any mechanical splice can fail and the last thing you want is a hidden splice to fail.

I am not seeing where it says that it can be non-accessable (hidden). It just says that you don't need to use exposed unsightly boxes.

I'm still confused though. What is the point of the product if it must be accessible? The "unsightlyness" is not from the junction box, it's from the fact that you need any kind of accessible panel. If you don't have a junction box, but still have a - I dont know - a door or removable cover or whatever, that's the problem. To me the fact that the product exists implies the wires can be non-accessible because otherwise it's no better visually than a junction box and 8x the price.
