Leviton 931-E – Frequently Asked Questions

1) What voltage and amperage is the Leviton 931-E straight blade plug rated for?
The Leviton 931-E is a 250V AC plug carrying a 50A amperage rating, with the description covering it as a 30/50-Amp device for heavy-current circuits. It is a 2-pole, 3-wire commercial grade plug, so it lands on 250V equipment circuits rather than standard 125V cord service.
2) Will a 250V 2-pole 3-wire straight blade plug work on a 125V 15-amp cord?
No. The 931-E is a 250V, 2-pole 3-wire straight blade device and its blade pattern will not enter a 125V 15-amp receptacle. For 125V 15-amp cord work, the Eaton Arrow Hart Ultra Grip straight blade plug is rated 15A 125V, and the Pass and Seymour PS5266X is a 15A 125V spec-grade plug with a nylon housing.
3) Is this a twist-lock plug or a straight blade plug?
Straight blade. The 931-E's blades push straight into a matching straight blade receptacle with no twist to lock, so it mates only with straight blade outlets of the same 250V 2-pole 3-wire pattern, not with locking receptacles.
4) Is the Leviton 931-E acceptable for a hospital or patient-care area?
It is a commercial grade device, not hospital grade, so it does not carry the green-dot hospital listing facilities require in patient-care spaces. Bryant offers hospital grade plugs for that use: the 8266T in NEMA 5-15P, the 8395T angle plug in NEMA 5-20P, and the 8666TSP watertight plug in N6-15P.
5) What is the closest equivalent to the Leviton 931-E for a 50-amp 250-volt cord connection?
The Bryant 7516NC is the nearest match in the same class of device. It is a rubber-bodied electrical plug in the NM10-50P series, so it is built around the same 50-amp two-pole three-wire family the Leviton 931-E serves at 250 volts. The practical difference is body material and style: the 931-E is a black commercial grade straight blade plug, while the 7516NC uses a rubber housing, which is the usual pick where the cord end gets dragged across a floor or dropped. Confirm the receptacle configuration in the field before ordering either, since a 50-amp two-pole three-wire opening and a 50-amp three-pole four-wire opening will not accept the same plug.
6) Can I use a Bryant 8266T or Eaton Arrow Hart AH5266 in place of the Leviton 931-E?
No. The Bryant 8266T is a NEMA 5-15P plug and the Eaton Arrow Hart Ultra Grip AH5266 is a 15-amp 125-volt straight blade plug, so both are 125-volt 15-amp cord ends. The Leviton 931-E is rated 250 volts at 50 amps. The blade pattern is different and the current capacity is a fraction of what the Leviton handles, so neither will enter a 250-volt 50-amp receptacle and neither should ever be fitted to a cord feeding equipment sized for that circuit. Use those two only on 15-amp 125-volt general-purpose cords.
7) I need a 250-volt plug for a healthcare space. Is the Leviton 931-E acceptable, or do I need a hospital grade device?
The Leviton 931-E is a commercial grade plug, not hospital grade, so for patient-care areas that require a listed hospital grade cord end it is not the right device. Among 250-volt options, the Bryant 8666TSP is a watertight hospital-grade plug in the N6-15P configuration, which is the 250-volt 15-amp pattern. For 125-volt circuits the hospital grade choices are the Bryant 8266T in NEMA 5-15P and the Bryant 8395T, an angle hospital-grade plug in NEMA 5-20P. All three are far below the 50-amp rating of the 931-E, so they cover receptacle-branch equipment cords rather than heavy machinery feeds.
8) Does a 3-wire 2-pole plug like this include a ground?
Yes. Two poles carry the ungrounded conductors and the third wire is the equipment ground, which is what makes it a grounding-type 250V connection for equipment and machinery. There is no neutral in this configuration, so it suits straight 240V loads rather than 120/240V appliances needing a neutral.
9) What is the Leviton part number to order for this 250V 50-amp plug?
Order Leviton 931-E. That is the manufacturer part number for the commercial grade 250V, 50A, 2-pole 3-wire straight blade plug, and it ships as a single model with no finish or configuration options to specify.
10) The cord end on our shop equipment keeps getting stepped on. Is there a tougher plug than the Leviton 931-E?
Body toughness and electrical rating are separate decisions here. The Leviton 931-E is a commercial grade straight blade plug rated 250 volts at 50 amps, and the Bryant 7516NC covers the same NM10-50P 50-amp configuration in a rubber body, which absorbs impact better than a rigid housing on a floor-level cord. If the equipment in question is actually on a 125-volt branch circuit rather than a 250-volt feeder, the ruggedized choices are the Pass and Seymour PS5266X, a 15-amp 125-volt extra-hard use spec-grade plug with a nylon housing and white face, and the Eaton Arrow Hart Ultra Grip, a 15-amp 125-volt industrial specification grade straight blade plug. Match the circuit first, then pick the body.
11) What should I use instead of the Leviton 931-E if the plug will be exposed to washdown or weather?
The 931-E is a commercial grade straight blade plug and is not a watertight device. Where the connection sits in a wet or washdown location, the Bryant 8666TSP is a watertight hospital-grade plug in the N6-15P configuration. That is a 250-volt device like the Leviton, but the 15-amp pattern, so it suits cord-connected equipment on a 15-amp branch rather than the 50-amp loads the 931-E is sized for. For a 50-amp connection in a wet location, plan on a weatherproof enclosure or cover for the connection point rather than swapping the plug down in rating.
12) What color is the Leviton 931-E plug body?
Black. If you are standardizing cord colors across a facility, note that the Pass and Seymour MaxGrip M3 nylon cord plug is a yellow body, which crews often use to flag temporary or portable cords.
