3M 7100175087 3M, Scotchlok, Electrical IDC 314U-POUCH, Pigtail, Self-Stripping, White, 22-14 AWG, 100 per pouch, 100 /Case

No stripping. The 314U is an insulation displacement connector, so the metal element cuts through the insulation as you crush the cap down. You lay the wires in full-jacketed and press. That is the whole point of the design and it is why these go in so much faster than a twist-on nut on a fixture whip or a low voltage run.

3M calls for the E-9BM crimping tool or a 9 in. lineman's pliers. Pliers are what most electricians actually reach for, and they work, but the jaw has to close the cap fully and flush. A partially seated cap means the IDC blade has not fully bitten the conductor and you get an intermittent connection later.

Up to three conductors. The 314U is rated for a maximum of 3 cores, so it will take a 2-wire or a 3-wire splice in the same body. It is a pigtail style connector, meaning the wires enter from one end and dead-end in the cap, so use it where the splice terminates, not where a run needs to pass through.

Voltage is fine: the 314U carries a maximum recommended rating of 600 V, so 120, 277 and 480 V branch circuits are all inside it. Wet or damp locations are a different answer. This connector is not moisture resistant and has no corrosion grease fill, so keep it in dry interior enclosures. For a buried, wet, or direct-burial splice you want a gel-filled connector instead.

No - they do different jobs. The 3M Scotchlok 314U is an insulation displacement pigtail connector with a nylon-insulated white body that joins up to 3 conductors from 22 AWG to 14 AWG, rated to 600 V and 105 C, and it strips the wire as the cap is pressed home with an E-9BM tool or 9 in. lineman's pliers. The Burndy BDTIBB is a wall mount intersystem bonding connector in stainless steel for #14-#2 AWG, intended to provide bonding terminations at the service, not to splice a pair of branch or control conductors inside a box. Order the 314U for the splice and the BDTIBB only if the requirement on the drawing is an intersystem bonding termination point.

No. The 314U is a dry-location connector - it is not moisture resistant and carries no grease fill against corrosion, so it suits low voltage splices inside an enclosure such as a 4 in. square box. For an outdoor or damp location, mount the splice inside a suitable box and fitting so the connection stays dry; a RACO 232MSCM 4 in. square welded box with M bracket at 2-1/8 in. deep gives the volume for several 314U pigtails, and a RACO 4734 SWIVEL-LOK 1 in. Type B liquidtight connector lands liquidtight conduit at it.

Rated to 105 C (221 F) maximum operating temperature, and the body is flame retardant nylon. That covers the typical 90 C conductor and the heat inside most luminaire wiring compartments. If the fixture label calls for a higher temperature splice than 105 C, use a high-temp connector instead.

RoHS 2011/65/EU compliant without exemption, and manufactured in the United States. That combination is what most institutional and government procurement offices are checking for on a submittal, so it is worth capturing on the cut sheet when you standardize a facility on these.

That is one of its better uses. The 314U is classed for low voltage application and reaches down to 22 AWG, which a standard twist-on nut struggles to grip reliably. Thermostat wire, door contact leads, and 18 or 20 AWG control pairs all sit inside the range. Just remember the maximum is three conductors per connector.

Different jobs. The 314U dead-ends a splice: two or three wires go in one end and stop there, which is what you want at a fixture or a device pigtail. A tap style product such as the Burndy Tapit line is built for branching off an uncut run conductor. If your run wire has to continue past the connection point, a pigtail is the wrong tool.

No. The 314U is an insulated nylon splice connector for conductors, not a bonding lug. For an intersystem bonding termination you want a purpose-built device like the Burndy BDTIBB BONDIT wall mount intersystem bonding connector, which is stainless steel and takes #14 through #2 AWG.

It is not an alternative - it is a polyethylene cover for Tapit tap connectors, so it protects a tap that has already been made rather than making the connection itself. The 3M Scotchlok 314U is a complete self-stripping insulation displacement connector: the white nylon-insulated body and cap contain the contact element, so no separate cover is needed once the cap is seated. If the job is a 22 to 14 AWG splice of two or three wires, the 314U is the item to order on its own.

The 3M Scotchlok 314U is the wire connector. It is an IDC connector that joins 22 to 14 AWG solid or stranded conductors, flame retardant, 600 V, made in the USA and supplied in pouches at 500 per case. The RACO 4734 is a SWIVEL-LOK 1 in. Type B liquidtight multi-position connector in nylon - a raceway fitting that terminates 1 in. liquidtight flexible conduit into an enclosure, with no wire termination function at all. A typical job uses both: the 4734 to land the conduit at the box, the 314U for the splices inside it.

Color is how the Scotchlok family is sorted by wire range on the truck. The 314U is white cap over white body, and that white combination is the 22-14 AWG pigtail. If you are standardizing a crew's kit, pull by color and you will not have to read the tiny molded number in a dark ceiling.

They ship in pouches, 500 units per case. The pouch packaging is meant to go in a pouch or bucket rather than a rigid box, which is why these get spec'd for crews doing repetitive fixture whips or control wiring where you burn through a hundred in a shift.
