if you look at 3.2 Applications on the spec sheet for the amp/tyco product, it says its listed for use in manufactured buildings, mobile homes, etc. I dont see anything saying its for use in site built construction.

I think they are legal for T-taps. from the UL:

GENERAL

This category covers self-contained interconnectors employing pressure cable connectors, insulation displacement or insulation piercing connectors for splicing or tapping nonmetallic (NM) sheathed cable. These interconnectors are intended for use in exposed or concealed locations in accordance with the following Articles of ANSI/NFPA 70, "National Electrical Code":

Article 545, Manufactured Buildings

What about 334.40(B)



Here is the link for the device that would be compliant

These devices can only be "factory installed", according to Section 3.4 of the manufacturer's instructions. They are not to be installed in the field. Sorry. :roll:

Any similar products that serve the same purpose, to be allowed by the NEC, must remain accessible by removal of an old-worked box or be exposed.

It complies with NEC 334.40(B)
 
Suprised no one asked the wiring method for the OP - if it were K&T - it very well could be a soldered connection and plastered over.... But not allowed for any other wiring method.

Neither solder or those NM interconnectors will work for OP.

What isn't? Tyco 3.4 or NEC 334.40(B)?
Click to expand...
Both.

The instructions are for a particular scenario and do not say that this means the device can only be factory installed. 3.2 is the general applications section. For the factory application, see section 3.4. For site assembly of factory-built homes, see section 3.5.


As for the NEC:
334.40(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 enclose the part of the cable from which any part of the covering has been removed. Where connections to conductors are by binding-screw terminals, there shall be available as many terminals as conductors.

...
Accessible (as applied to wiring methods). Capable of being removed or exposed without damaging the building structure or finish or not permanently closed in by the structure or finish of the building.
...
Concealed. Rendered inaccessible by the structure or finish of the building. Wires in concealed raceways are considered concealed, even though they may become accessible by withdrawing them.
