Ideal Industries WT3-1 – Frequently Asked Questions

1) Is the Ideal WT3 orange wire connector UL Listed for use in a junction box?
The WireTwist WT3 is UL Listed, and its shell is UL 94V-2 flame retardant thermoplastic. That is what lets it be used for splices inside a junction box or enclosure per NEC, in residential, commercial and industrial work. Part number is WT3-1.
2) What temperature can the Ideal WireTwist WT3 connector handle for light fixture and ballast splices?
Rated for 105 C (221 F) continuous operating temperature, which is why it gets used on fixture whips, ballast and LED driver connections where the box runs hot.
3) Is the Ideal WT3 the same kind of connector as a Leviton ML2-C or a Pass & Seymour Turnlok 27W?
No, and this catches buyers out because all three are called connectors. The WT3 is a twist-on splice cap for joining conductors inside a box. The Leviton ML2-C is a midget cord connector, sold in packs of 100, and the Pass & Seymour Turnlok 27W is a 20A watertight NEMA 4X/6P locking cord connector. Those two terminate a cord to a plug-and-receptacle system; they will not splice wires in a junction box. If you need a hospital grade cord connector instead, the Leviton 8319-C is a NEMA 5-20R hospital grade connector and the Bryant 8269T is a hospital grade NEMA 5-15R.
4) Can I use the Ideal WT3 wire connector in a wet or outdoor location?
The WT3 WireTwist is a twist-on splice connector with a UL 94V-2 flame-retardant shell and a 105 C temperature rating, intended for splices made inside a junction box or electrical enclosure per NEC requirements; it carries no watertight or weatherproof rating of its own, so the enclosure has to provide that protection. Where the connection point itself must be sealed, the Pass and Seymour Turnlok 27W series watertight connector is rated NEMA 4X/6P, and the Bryant WPC series is a weatherproof wiring connector fitting.
5) Is the Leviton 8319-C a substitute for the Ideal WT3 orange wire connector?
No. The Ideal WireTwist WT3 is a twist-on splice connector with a fixed square-wire spring inside a flame-retardant shell, installed by rotating it clockwise onto stripped conductors inside a junction box. The Leviton 8319-C is a hospital grade NEMA 5-20R connector, which is a cord-mounted receptacle body used to terminate a flexible cord so equipment can be plugged into it. Both are sold 100 to a box, but they do different jobs: use the WT3 to splice conductors, and a NEMA 5-20R connector body only where a cord-and-plug connection is required.
6) I need a connector for a cord-and-plug equipment hookup, not a splice. What should I use instead of the WT3?
The WT3 WireTwist is a twist-on splice connector for joining conductors inside a junction box or enclosure, so it is not the part for terminating a flexible cord. For cord-end terminations, straight blade connector bodies cover that use: the Leviton 15W33 is an industrial grade 3-wire 2-pole straight blade connector rated 125V 20A, and the Bryant 8269T is a hospital grade NEMA 5-15R connector. Pick by the configuration and amperage of the circuit you are feeding.
7) How many wire connectors come in a box of Ideal WT3-1?
WT3-1 ships as a box of 100 orange WireTwist connectors, so it is a stocking quantity for a van or an MRO shelf rather than a single splice.
8) Why is this WireTwist connector orange, and does the color mean anything?
Orange is Ideal's color code for the WT3 size within the WireTwist line. Twist-on connectors are color coded by capacity, so crews sort them by shell color on the job instead of reading the shell. If your spec or your existing stock calls out a different WireTwist color, you are being pointed at a different size connector, not a finish choice.
9) What is a fixed square-wire spring and does it hold better than a standard wire nut?
Inside the WT3 shell is a fixed square-wire spring rather than a free-floating coil. The square cross section bites the conductors and the fixed mounting keeps contact pressure consistent, so the spring does not fatigue or back out as it can on conventional wire nuts. The shell also has a positive grip exterior for turning by hand and a deep skirt that guards against flash-over at the base of the splice.
10) What is the difference between the Ideal WT3 orange connector and the Leviton ML2-C midget connector?
The Ideal WT3 is an orange-coded WireTwist twist-on splice connector with a fixed square-wire spring, deep skirt, and UL 94V-2 flame-retardant shell, UL Listed and rated to 105 C. The Leviton ML2-C is a midget connector for electrical wiring from the ML2 series, supplied 100 to a pack like the WT3 box of 100. They are not interchangeable in form: the WT3 is applied by clockwise rotation onto stripped conductors, so match the part to whether you are splicing conductors or making a small cord connection.
11) How do you install a twist-on WireTwist connector correctly?
Strip the conductors to clean copper, seat them fully into the connector opening, then rotate the shell clockwise under firm pressure until it is tight. Confirm every conductor is captured in the spring, tug test each wire, and close the splice into a box or enclosure per NEC. If a conductor pulls free on the tug test, cut back and redo it; the deep skirt should cover the bare copper when the splice is finished.
