Leviton 2440 – Frequently Asked Questions

1) Can I use the Leviton 2440 on a 3-phase delta system?
No. The 2440 is rated 120/208V, which is a 4-wire wye system: three ungrounded conductors at 120V to neutral and 208V between phases. A 240V delta or 480V system needs a different device entirely. If your equipment is 3-phase 120/208V with a neutral, this is the right configuration.
2) Is the Leviton 2440 a surface-mount or flush-mount receptacle?
Flush mount. The 2440 sets into the mounting surface for a low-profile installation, so it goes into a box or opening rather than sitting proud on a surface-mount housing. If your run is exposed conduit on a plant wall and you want the device standing off the surface, you need a surface-mount locking receptacle instead.
3) Will a standard industrial receptacle hold up in a plant with solvents and oil exposure?
That is what the 2440's body is for. It is molded in Leviton V-O-Max thermoplastic, an impact- and chemical-resistant compound that resists degradation from solvents, oils and plant chemicals, and takes repeated knocks on a plant floor. Standard commercial-grade devices use plastics that embrittle or craze under that exposure.
4) Will the Leviton 2440 keep a machine cord from pulling loose from vibration?
Yes, that is the point of the locking pattern. The L18-20R contacts twist and lock the plug in place, so the connection stays engaged under vibration and equipment movement rather than backing out like a straight-blade receptacle would. It is a common choice for 3-phase motor and equipment connections on a plant floor.
5) How many conductors do I need to land on the Leviton 2440?
The 2440 is an L18-20R, a 3-pole 4-wire configuration: three phase conductors and a neutral. There is no equipment grounding pin in the L18 pattern, so grounding is handled through the raceway or box per your installation. Pull your branch circuit accordingly before you set the device.
6) What is the difference between Industrial Grade and commercial grade on a locking receptacle like this?
Industrial Grade, which is how the Leviton 2440 is built, means a higher duty-cycle and durability standard than a commercial-grade device: tougher housing material and construction intended for repeated plugging cycles rather than occasional use. For a machine cord that gets unplugged every shift, that distinction is the one that matters.
