IDEAL Industries 30-249 Pre-Insulated Crimp Connectors, 1000 Pack

The 30-249 is rated for a minimum combination of one #22 with one #18, up to a maximum of one #12 with one #16, at 600V. So it covers small mixed-gauge splices in fixtures and control wiring, not conductors heavier than #12. If you are splicing two #10s or larger, this is the wrong connector.

Yes. The 30-249 pre-insulated crimp connectors are rated to 1,000 V maximum in fixtures and signs, with a maximum temperature rating of 150. The shell is UL 94V-2 flame-retardant and rated at 105 C (221 F), which is the limit for the insulation itself.

No, and this trips people up because the word connector covers two different products. The 30-249 is a pre-insulated crimp splice for joining conductors inside a box or fixture. Items like the Leviton 8319-C Hospital Grade NEMA 5-20R connector, the Leviton 15W33 industrial grade straight blade connector, or the Pass & Seymour Turnlok 27W Series 20A watertight connector are cord-end plug bodies that mate with a plug or receptacle. If you need a female cord end, the 30-249 is not it.

The IDEAL 30-249 is a pre-insulated crimp splice with a UL 94V-2 flame-retardant shell intended for permanent pressure connections in fixtures and signs, with no weatherproof housing of its own. For an exposed wet or outdoor connection, the Bryant WPC series weatherproof wiring connector fitting or the Pass and Seymour Turnlok 27W series 20A watertight connector, rated NEMA 4X/6P, are the connector types built for that environment. A 30-249 splice can still be used where it sits inside an enclosure that provides the wet-location protection.

No. The IDEAL 30-249 is a pre-insulated crimp connector, a pressure-type splice device that is crimped onto the wires to make a permanent connection, and it handles a wire combination range of 600V Min. 1 #22 w/1 #18 Max. 1 #12 w/ 1 #16. The Leviton ML2-C is a midget connector for electrical wiring, a separable cord-connector body rather than a crimped splice. If the job is joining conductors permanently inside a fixture or sign, the 30-249 is the crimp part; if the job needs a cord end that can be unplugged, the ML2-C is the wiring device family to look at.

No. Hospital grade is a listing applied to receptacles and cord connectors, and the parts carrying it in that class are devices such as the Bryant 8269T hospital grade NEMA 5-15R connector and the Leviton 8319-C hospital grade NEMA 5-20R connector. The IDEAL 30-249 is a pre-insulated crimp splice for joining conductors, so it serves a different point in the circuit and does not satisfy a hospital grade device call-out. The two are commonly used on the same job: the crimp splice inside the box or fixture, the hospital grade connector at the cord end.

One carton of 1,000. It is a bulk pack meant for panel shops, OEM assembly, and MRO crews doing repeat splices, not a small contractor bag.

For vibration, yes. The IDEAL 30-249 is a pressure-type crimp connector making a permanent mechanical connection, which is why IDEAL positions it for high-vibration environments and OEM work. A twist-on connector can back off under sustained vibration; a crimp cannot be removed and re-used, so use it where the splice is final.

The 30-249 shells are translucent, so you can look through the barrel and confirm the conductors are fully inserted before and after crimping. The beveled opening eases wire entry and the flared skirt keeps turned-back strands from sitting outside the barrel, which is the usual cause of a bad crimp.

Yes. These are pressure-type crimp connectors, so each one has to be compressed with a crimping tool sized for insulated terminals. No tool is supplied in the carton of 1,000, so order crimpers separately if your crew does not already carry them.

They cover different needs. The Leviton 15W33 industrial grade straight blade connector is a 3-wire 2-pole 125V 20A device for making a connectable cord end. The IDEAL 30-249 is a crimped, permanent pressure connection marketed for high vibration environments and OEM installations, and it ships as a carton of 1,000. A plant standardizing on both would use the 15W33 at cord terminations and the 30-249 for the in-fixture or in-panel splices behind them.

That is what they are built for. The 30-249 uses a compact body specifically so it fits into tight locations such as fixture canopies and crowded boxes, where a twist-on connector's bulk is the problem.

Order IDEAL Industries 30-249. It is a single catalog number covering the pre-insulated crimp connector in a 1,000 piece carton, with no finish or size options to specify.

The IDEAL 30-249 pre-insulated crimp connector is cartoned at 1,000 pieces. Among connectors packed at 100, the Leviton ML2-C midget connector and the Leviton 8319-C hospital grade NEMA 5-20R connector ship in packs of that size, though both are cord-connector devices rather than crimp splices, so they are only an option if the application allows a separable connection instead of a permanent crimped one.
