Check Price on Amazon

This Leviton 5461-R is the benchmark for a dedicated 20A 250V circuit in a workshop or garage. The impact-resistant thermoplastic nylon body houses triple-wipe brass T contacts that maintain low resistance even as the outlet ages — critical for a Level 2 EV charger pulling 16 amps for hours. The self-grounding brass clip is permanently staked, so you skip the bonding jumper.

Installers often prefer this model because it includes clamp-plate terminals on the line and neutral side — you can insert 12 AWG stranded or solid copper without looping the wire around a screw. The red color serves as an immediate visual reminder that this is a 250V circuit, reducing the chance of accidentally plugging in a 120V device. Users running 6-20 EV chargers consistently report cooler operation compared to builder-grade units.

The only real friction point is that the terminal screws are small relative to the thick 10 AWG wire sometimes used for long runs — you may need to tin stranded wire or use a pigtail. Backed by a ten-year limited warranty, this receptacle justifies its mid-range position with metallurgy and retention force that lower-cost outlets cannot match.

When your 6-20 outlet lives outdoors — at an RV pad, a detached garage exterior, or a covered patio for a pool pump — the Leviton W5461-E adds a layer of resilience that standard industrial units lack. The weather-resistant designation means the thermoplastic nylon body resists UV degradation, cold-impact damage, and corrosion from humidity. Nickel-plated mounting straps and stainless-steel screws prevent rust streaking on white or black faces.

Internal wiring clamps accept both back and side wiring, which gives you flexibility when the box is tight. The self-grounding clip is brass and permanently staked, eliminating the green grounding screw pigtail. Users who installed this for outdoor EV charging report zero discoloration after two seasons of direct sun, and the plug retention feels as tight as the day it was wired.

You should pair this outlet with a high-quality weatherproof cover (the Sealproof 1-Gang is a popular match) to protect the face from direct rain. A few users noted that the brass-colored screw on the ground terminal can back out during shipping — check it before you begin installation.

The Maxxima MEW-R202-02 brings a 20A 250V single receptacle into an accessible price point without skipping UL listing. This is a commercial-grade unit with a shallow body profile designed to fit standard junction boxes even when crammed with 12-2 or 10-2 Romex. Each pack includes two white wall plates, which simplifies renovation work where you need multiple 6-20R locations.

The copper, iron, and plastic construction feels solid enough for intermittent loads like a refrigerated wine cabinet or a stationary saw that cycles on and off. However, the wiring terminals are side-screw only — no clamp plates — so you will need to loop 12 AWG wire cleanly around the screw. Some electricians have reported that the screw heads are slightly smaller than Leviton models, requiring a precise #1 Phillips bit.

EV owners using a NEMA 6-20 Tesla mobile connector have reported stable performance over 10 months, but for continuous 16-amp duty cycles, the industrial-grade Leviton 5461 offers greater long-term contact durability. If budget is the primary constraint and the load is moderate, this Maxxima two-pack provides excellent value per outlet.

While the ELEGRP GFCI is a 125V device — not a 250V 6-20R — it belongs in this guide because many buyers searching for a 220 20 Amp outlet also need GFCI protection on their 120V bathroom, kitchen, or garage circuits wired with 12 AWG. This 5-pack delivers a narrow-body design that leaves extra room in the electrical box, and the patented self-test runs every 5 seconds — far exceeding the UL minimum of every 3 hours.

The dual-protection system uses twin solenoids and a double silicon-controlled rectifier to handle ground faults, and the Reset-Disable feature prevents the outlet from re-energizing if the GFCI circuitry is compromised. For wet-location compliance in a garage or basement, this unit carries both UL and FCC certifications. Users have noted that the ground screw sits very close to the mounting strap, making it tricky to wrap 12 AWG ground wire cleanly.

If you are wiring a new 250V outlet for an EV charger or a welder, you will need GFCI at the breaker, not at the receptacle — but this ELEGRP pack is an outstanding companion for the 120V general-use outlets on the same project.

The Greencycle 20A GFCI outlet provides ground-fault interruption within 20 milliseconds (0.02 seconds), making it a solid choice for outdoor 120V circuits near pools, patios, or gardens where moisture is a daily risk. ETL certified and built with high-impact thermoplastic, this unit includes the RESET and TEST buttons with a green LED indicator that confirms proper wiring — no green light means miswiring or a damaged unit.

The weather-resistant construction adds UV protection to prevent the white face from yellowing in direct sun, and the decorative wall plate included in each pack creates a flush, modern look. Three outlets per pack at this price point effectively undercuts Leviton’s standard GFCI, which makes it attractive for whole-house GFCI upgrades where each bathroom and garage needs one.

Be aware that the initial plug insertion feels stiff due to the safety-contact design, and the snap-on cover can be difficult to attach without a small pry tool. As with the ELEGRP, this is a 125V device — it cannot serve as a 250V 6-20R, but it is an economical companion for any 20A project requiring GFCI compliance in wet areas.

The BESTTEN 20-Pack delivers a staggering per-unit cost that makes whole-home 20A upgrades financially painless. These are 125V decorator-style receptacles (rated 20A/125V/2500W) with a glossy white polycarbonate face, side-wire terminals intended for 12 AWG solid copper, and break-off tabs for split-circuit applications. Each outlet comes with a matching wall plate and screws — no separate purchase needed.

Polycarbonate construction provides decent impact resistance for residential use, and the UL listing confirms basic safety compliance. One experienced electrician noted that the rear-wire entry holes accept 12 AWG solid wire but require the top screw to clamp down — they are not push-in style, which is actually safer for 20A circuits. Users have reported that plugs fit snugly on first insertion but loosen slightly over repeated use, which is characteristic of residential-grade contacts.

This pack is best for large-scale renovations where every room gets 20A receptacles, or for landlords outfitting multiple units. However, for a 250V 6-20R circuit, you would need to look elsewhere — these are 125V devices and will not accept a NEMA 6-20 plug.

The HYDUUU 6-20R replacement ends serve a specific but common need: repairing or building a custom heavy-duty extension cord for a 20A 250V appliance. Each connector uses PA66 nylon — a high-temperature, flame-retardant material that handles the heat generated by continuous 16A current through a cord. The adjustable wire range (AWG 18-12) covers both standard 12 AWG extension cord and thinner gauge control wiring.

Wiring is straightforward: strip 1-1/8 inches of outer jacket, strip each leg to roughly 1/2 inch, insert into the brass terminals, and tighten. The plug grip is firm, and users employing these ends for EV charger extension cords report minimal resistance at the connection point. The UL listing adds confidence that the internal copper contacts will not deform under thermal cycling.

One detail to watch: the screws use a coarse thread pattern that backs out very quickly — using the correct sized screwdriver and not over-torquing is essential. These are not designed for permanent wall installation; they are cord-end connectors meant for flexible SJOW or SOOW cable.
