3M Scotchlok Female QuickSlide Disconnect, T-Tap Nylon Insulated

That is exactly what it does. The Scotchlok 952X is a T-tap insulation displacement connector: you lay the run wire into the channel and close the connector, and the self-stripping element cuts through the insulation and makes contact mid-span, so the existing conductor stays intact. The tapped branch ends in a 0.25 inch female quick-disconnect for a standard male tab.

It is built for 18-14 AWG conductors, and the insulation outside diameter has to be 0.145 inch (3.7 mm) or less to seat in the channel. Oversized jacket, such as heavy-wall or double-insulated cable in that gauge range, will not close properly even if the copper size is right.

Yes. The QuickSlide female end is 0.25 inch (6.35 mm) wide, which is the common 1/4 inch male tab size used on switches, relays, and appliance terminals.

No. It has no corrosion grease fill, so it is a dry-location connector. For direct-burial or submerged taps you want a gel-filled or encapsulated connector instead.

No, those two solve different problems. The 3M Scotchlok 952X is a nylon-insulated, self-stripping insulation displacement connector that taps a wire in mid-span without cutting it and terminates in a 0.25 in female QuickSlide disconnect. The Thomas & Betts 306 is a straight Tite-Bite connector for 1 in flexible metal conduit, which is a raceway fitting and does not terminate conductors. If you are branching a circuit off an existing run and landing it on a 1/4 in male tab, the Scotchlok is the part; if you are landing FMC into a box, the 306 is.

No. The Scotchlok 952X is built for 18-14 AWG with a maximum insulation outside diameter of 0.145 in, so a heavier conductor will not seat in the self-stripping element. For bonding work on larger conductors, the Burndy BDTIBB BONDIT wall mount intersystem bonding connector is stainless steel and accepts #14 through #2 AWG.

3M calls for the E-9BM crimping tool, and mechanics (slip joint) pliers are the accepted alternative. No stripping is needed first; the element does the stripping as the cover is pressed home. Do not close these with lineman's pliers side cutters, since the element needs even flat pressure.

Yes, and well beyond it. The maximum recommended voltage is 600 V, so it covers 12 V and 24 V vehicle and control circuits as well as line-voltage control wiring within its 18-14 AWG range.

The rated ceiling is 105 C (221 F). The insulator is flame-retardant nylon and the contact element is tin-plated brass, so engine-bay and equipment-enclosure heat is within range, but keep them off exhaust or heater surfaces that run past 105 C.

They fall under UL file E70512, and the listing is marked UL Listed for AWG only. That matters on jobs using metric-sized conductor: the UL coverage applies to AWG wire, so specify AWG for the tapped run.

Different jobs entirely. The Scotchlok 952X is a wire-to-wire insulation displacement tap that branches a live conductor and terminates in a female quick-disconnect. Products like the Thomas and Betts 306 Tite-Bite 1 inch FMC fitting or the RACO 4734 SWIVEL-LOK liquidtight connector are raceway fittings that land conduit on a box; they make no electrical connection to the conductor. If you need to pick up a ground reference at the service rather than tap a branch, that is a bonding device such as the Burndy BDTIBB BONDIT intersystem bonding connector for #14-#2 AWG.

No. The Burndy UCCOVER1BOX25 is a polyethylene cover for Burndy Tapit tap connectors, sized and shaped to that family. The 3M Scotchlok 952X needs no separate cover because the connector body is nylon insulation with an FR nylon insulator over a tin-plated brass element, flame retardant, and rated to 600 V and 105 C once closed.

The 952X closes with a 3M Crimping Tool E-9BM or ordinary mechanics slip joint pliers, so no dedicated die-set crimper is required for a truck stock install. That is a different install path from raceway fittings such as the RACO 4734 SWIVEL-LOK nylon liquidtight connector or the RACO 232MSCM square box with STAB-IT connector, which are assembled to conduit and boxes rather than crimped onto conductors.

The two orderable items are MPN 7000058872 and MPN 7000058873, both 952X female QuickSlide T-taps for 18-14 AWG supplied in the bottle pack, 10 packs per case. Order by the MPN your spec calls out.

Both. Country of origin is the United States, and 3M states RoHS 2011/65/EU compliance without exemption, which covers the usual procurement questions on a domestic-preference or environmental spec.
