3M 7000058006 3M, Scotchlok, Electrical IDC 314U-BIN, Pigtail, Self-Stripping, Flame Retardant, White, 22-14 AWG, 100 /Case

The Scotchlok 314U-BIN takes 22 AWG through 14 AWG conductors, solid or stranded, which is 0.5 mm2 up to 1.5 mm2 metric. Both the run wire and the tap wire have to be within that range, and each wire's insulation outer diameter has to be 0.155 in (3.9 mm) or smaller. If your run conductor is 12 AWG or larger, this is the wrong connector.

No stripping. The 314U-BIN is an insulation displacement connector, so the metal element cuts through the insulation as you crimp the cap down with pliers. That is the whole point of it on a fixture whip or a lighting drop: you lay the wire in, squeeze, done. Because it displaces insulation rather than clamping bare copper, the insulation OD limit of 0.155 in matters as much as the AWG size.

Maximum recommended voltage on the 314U-BIN is 600 V, and 3M classes it as a low voltage application connector. That covers standard 120/277 V branch circuit and fixture wiring. It carries UL file number E23438.

No. The 314U-BIN is a dry-location connector: it is not moisture resistant and it has no corrosion-inhibiting grease fill. For damp, wet, or buried splices you need a gel-filled or encapsulated connector. Indoors in a box, it's fine.

No, they solve different problems. The 3M Scotchlok 314U-BIN is an insulation displacement pigtail connector in flame retardant nylon that joins 22 to 14 AWG low voltage branch conductors at up to 600 V. The Burndy BDTIBB BONDIT is a wall mount intersystem bonding connector in stainless steel for #14 to #2 AWG bonding conductors, used to land telephone, cable and satellite bonding leads at the service. If the job is splicing or tapping small building wire, the 314U-BIN is the connector; if the job is an intersystem bonding termination point on the exterior wall, the BDTIBB is.

The 314U-BIN is not the one for wet or buried work. It is not moisture resistant and is not grease filled against corrosion, so it belongs in dry interior low voltage and branch circuit splicing up to 600 V and 105 C. For a raceway entering an enclosure in a wet or outdoor location, a liquidtight fitting such as the RACO 4734 SWIVEL-LOK 1 inch Type B multi-position nylon connector handles the conduit termination, though that is a raceway fitting rather than a wire splice.

A pigtail connector terminates wires at a dead end rather than tapping a through run. The 314U-BIN joins 2 or 3 wires coming into the cap, so it's what you use to splice a branch to a fixture lead or combine conductors at the end of a run. If you need to tap a hot without cutting it, you want a run-and-tap style connector instead, not this one.

Maximum operating temperature is 105 C (221 F). That covers 90 C THHN terminations and typical luminaire junction box temperatures. In a high heat process area above 105 C, use a different termination method.

No. The 3M Scotchlok 314U-BIN is the splice itself, a self-contained insulated pigtail connector. If what you need is an insulating cover to go over a separate tap connector, look at the Burndy UCCOVER1BOX25 Tapit polyethylene tap connector cover instead.

No. The 314U-BIN is a 22-14 AWG insulated wire splice for branch circuit and fixture work, not a grounding or bonding device. For intersystem bonding termination, the Burndy BDTIBB BONDIT wall mount intersystem bonding connector is the stainless steel part built for that, rated #14 through #2 AWG.

No. The UCCOVER1BOX25 is a polyethylene tap connector cover made for Burndy Tapit series tap connectors, and it is sized to that family. The 3M Scotchlok 314U-BIN carries its own flame retardant nylon insulation in white and does not take a separate cover, so no additional housing is needed or fitted for it.

Read the callout carefully, because the word connector covers two different items. The 3M Scotchlok 314U-BIN is a wire splicing device, an insulation displacement pigtail for 22 to 14 AWG conductors, and it lives inside the box. If the drawing means the box itself with an integral cable clamp, that is a product like the RACO 232MSCM, a 4 in. square welded box 2-1/8 in. deep with a STAB-IT connector and an M bracket. A typical rough-in uses the box for the cable entry and the 314U-BIN for the splices made inside it.

Cap and body are flame retardant nylon insulation, white throughout. The flame retardant property is a stated attribute of the material, which is why electricians favor these in luminaire and ballast compartments.

Yes on both counts. The 314U-BIN is RoHS 2011/65/EU compliant without exemption, and country of origin is the United States. That combination matters on government and institutional specs that carry domestic-sourcing language.

They ship bulk rather than carded or blister packed, ordered under 3M MPN 7000058006. Bulk packaging is what you want for a truck stock bin or an MRO crib where techs grab a handful at a time.
