Cooper Wiring Devices COO-5 – Frequently Asked Questions

1) Will the Cooper L1430P plug fit the cord on my 30 amp generator cordset?
The L1430P accepts cord with an outside diameter of 0.25 to 0.69 inches (6.4 to 17.5 mm). Typical 10/4 SOOW generator cord falls inside that window; anything larger than 0.69 inches will not clamp properly in the cord grip, and anything thinner than 0.25 inches won't be gripped securely. Measure the jacket OD, not the conductor gauge, before you order.
2) How many wires do I need to terminate on the Cooper L1430P?
Four: two hot legs, a neutral and an equipment ground. It is a three-pole, four-wire device, so a three-wire cord will not land correctly. Terminations are made by the back-wiring method, so you strip and land conductors into the back of the plug body rather than wrapping blade screws.
3) Can I run both 120V and 240V loads through this plug?
Yes. The L14-30 configuration is rated 125/250V and carries two hot legs plus a neutral, so a cordset built on the L1430P can feed 240V equipment and 120V branch loads off either leg. That is why it is the standard interface for portable generator transfer setups.
4) Will a Cooper L1430P hold up outdoors on a construction site in winter?
It is rated for continuous service from -20 to 60 degrees C (-4 to 140 degrees F) and built as a severe duty locking connector with a thermoplastic body, so cold-weather temporary power and jobsite distribution are within its range. Note it is a plug body, not a weatherproof enclosure, so wet-location protection still comes from how the connection is made up and where it sits.
5) Is this plug good enough for an industrial machine, or do I need a heavier spec device?
The L1430P is a commercial grade device with brass contacts, intended for industrial equipment, portable power distribution and manufacturing feeds. Brass gives the conductivity and corrosion resistance for repeated make-and-break in a plant environment. For hostile wash-down or hazardous classified areas you would be specifying a different family of connector altogether, not a standard locking plug.
6) Will this twist-lock plug pull out if the cord gets yanked?
The L14-30 pattern is a twist-lock: you insert and rotate so the curved blades seat behind the receptacle contacts, which resists straight-pull disconnection. That is the main reason it is specified over a straight-blade plug for generators and portable distribution where cords get dragged.
7) What color and part number should I specify when ordering the Cooper L14-30 plug?
Order Cooper Wiring Devices part L1430P. It is supplied in black as a standard locking plug body, 30A 125/250V, three-pole four-wire. There are no finish or amperage options to choose on it.
