Eaton 8452N – Frequently Asked Questions

1) What size cord conductors can I land in the Eaton 50A 250V straight blade plug?
Terminals take #12 through #4 AWG, so it covers most 50A portable cord builds (typically #6 AWG copper) and gives room up to #4 for long runs. Terminations are screw type using the back wire method, so conductors go in behind the terminal plate and clamp down rather than wrapping a post.
2) The range circuit only has three conductors, no separate ground. Is the Eaton 8452N the right plug?
No. The Eaton 8452N is a three-pole, four-wire grounding device in the NEMA 15-50P configuration, so it needs four conductors. For a three-wire two-pole 250V cord at 30 or 50 amps, the Leviton 931-E is a commercial grade straight blade plug rated 3-wire 2-pole, 250V AC, 30/50-amp. Confirm the receptacle configuration in the wall before choosing, since a 15-50P blade pattern will not enter a three-wire outlet.
3) Is the Bryant 7516NC a drop-in replacement for the Eaton 8452N on a 50 amp cord?
No, they are different configurations. The Eaton 8452N is a NEMA 15-50P device, while the Bryant 7516NC is an NM10-50P series plug. Both are 50 amp class devices, but the blade patterns and pole/wire counts differ, so one will not mate with the other's receptacle. The Eaton also uses a nylon face and body, where the Bryant 7516NC is a rubber plug.
4) What is the closest equivalent to the Eaton 8452N plug if the cord set needs to exit at an angle instead of straight out?
The Eaton 8452N is a straight blade, straight body plug wired three-pole four-wire with a grounding conductor. For the same three-pole four-wire straight blade arrangement in an angled body, the Leviton 275-E is a commercial grade 4-wire 3-pole straight blade angle plug. The difference to weigh is device grade: the Eaton is an extra heavy-duty industrial specification grade device, while the Leviton 275-E is rated commercial grade.
5) Is the Eaton 8452N tough enough for a shop floor or is it just a bench device?
It is built as an extra heavy-duty industrial specification grade device, with a nylon face and body and brass contacts. Nylon holds up to impact and solvents better than thermoplastic, which is what you want on a cord cap that gets dragged and dropped. It is UL Listed.
6) What else could I use if I only need a two-pole 250V plug instead of three-pole?
For a straight 250V single-phase load with no third hot leg, the Leviton 5666-C is a 3-wire 2-pole industrial grade straight blade plug rated 250V 1-phase, and the Leviton 931-E is a commercial grade 3-wire 2-pole 250V unit covering 30/50-amp. The Eaton 8452N only makes sense when the equipment actually needs three poles plus ground.
7) Can a hospital grade plug like the Bryant 8266T be used in place of the Eaton 8452N?
Not for the same circuit. The Eaton 8452N is a 50A 250V device in the NEMA 15-50P configuration for industrial, range and dryer service. The Bryant 8266T is a hospital grade plug in the NEMA 5-15P configuration, which is a 125V general-purpose blade pattern. Hospital grade devices such as the Bryant 8266T and the angle-bodied Bryant 8395T in NEMA 5-20P are selected for patient care area cord sets, not for 50 amp equipment feeds.
8) What should be used instead of the Eaton 8452N on a 250V single-phase two-pole machine cord?
The Leviton 5666-C is a 3-wire 2-pole polarized industrial grade straight blade plug for 250-volt single-phase service, which matches a two-pole machine cord that the Eaton 8452N does not. The Eaton 8452N is a three-pole, four-wire grounding device accepting #12-4 AWG conductors, so it suits larger four-conductor feeds; both are industrial grade straight blade devices, so the choice comes down to the conductor count in the cord.
9) Is there a plug similar to the Eaton 8452N for a 20A 125V extension cord that needs a low-profile connection?
Yes, but at a different rating. The Pass and Seymour EHU series PS5366SSAN is an angled straight blade plug rated 20A 125V, which keeps the cord close to the wall. The Eaton 8452N is a straight body device rated 50A 250V with screw terminals and back wire termination, so it is the heavier device and does not serve a 20 amp 125V cord.
10) What color is the Eaton 8452N and how does it ship?
Gray nylon body, and it comes as a core pack. The part number to order is 8452N under Eaton's Arrow Hart line.
