Leviton 5266-C – Frequently Asked Questions

1) Will a Leviton 5466-C plug fit a standard 20A 250V receptacle?
The Leviton industrial grade straight blade plug in NEMA 6-20P configuration mates with any 20A, 250V straight blade receptacle wired to the NEMA 6-20 pattern. It is a 2-pole, 3-wire grounding plug, so the receptacle must have a ground. It will not enter a 5-15 or 5-20 receptacle: the 250V 6-20 blade pattern is deliberately different so you can't cross-connect 125V and 250V circuits.
2) What is the difference between Leviton 5266-C and 5466-C plugs?
Two different circuits entirely. The 5266-C is the 15A, 125V NEMA 5-15P version, the everyday 120V cord plug. The 5466-C is 20A, 250V NEMA 6-20P for single-phase 240V equipment. Order by the voltage of the circuit the cord is landing on, not by the cord itself.
3) Can I use a NEMA 6-20P plug on a three phase machine?
No. This plug is 2-pole, 3-wire, single phase at 250V. It carries two hot legs plus ground, with no neutral and no third phase conductor. A three phase load needs a 3-pole 4-wire device instead.
4) Is this Leviton straight blade plug industrial grade or just commercial spec?
Industrial grade. That is the construction tier Leviton builds it to, intended for plant floors, job sites, and facility power distribution rather than light-duty residential cord sets. For an MRO buyer standardizing on one plug across a facility, this is the heavier of Leviton's straight blade lines.
5) Can I put this plug on a 240V machine that draws 25 amps?
No. The rating is 20A at 250V, so the connected load has to stay within that. A 25A load needs a 30A device such as a NEMA 6-30P, and the branch circuit and cord have to be sized to match.
6) Is the Leviton 6-20P plug polarized, and does that matter on a 250V circuit?
The blades are polarized, so the plug only goes in one way. On a 6-20 250V circuit both blades are hot legs, so the keying is there to stop you inserting it into a different NEMA pattern and to keep the ground pin oriented correctly rather than to separate hot from neutral.
