Leviton 30 Amp, 250V, NEMA 6-30R Receptacle
Best for industrial environments that demand a flush-mount, straight-blade 6-30R with a robust steel strap. This model emphasizes reliability under harsh conditions and supports various configurations, including isolated ground or tamper-resistant variants. Use when you need a durable, straight-blade 240V outlet for welders or generators. Caution: verify wiring method and panel compatibility before installation.
Leviton 30 Amp, 125/250V, NEMA 10-30R Receptacle
This 3P, 3W non-grounding receptacle suits older installations or specific equipment setups that use a 10-30R configuration. It features heavy-gauge copper alloy contacts with clearly marked terminals to speed wiring. Best for older generator connections or legacy circuits where a 10-30R is required. Choose this if your system is designed for non-grounding outlets, and avoid if you need isolated grounding.
Leviton 2620 30 Amp, 250V Receptacle
Best for locking-type installations where secure plug engagement matters. This industrial-grade, grounding receptacle includes color-coding for quick voltage identification and carries UL/Fed./CSA/NOM listings with a V-0 flammability rating. It’s a solid choice for demanding environments where a locking connection reduces accidental disconnections. Limitation: locking outlets require compatible plugs and housings.
ELEGRP 30 Amps 250V Flush Mount Receptacle
Best for straight blade 6-30R needs in welded or generator setups. This flush-mount receptacle uses a heavy-gauge galvanized steel strap and a tough nylon housing with brass contacts for reliable conductivity. It fits in standard wall boxes and plates, offering straightforward installation. Caution: ensure the mounting depth and box size match your enclosure requirements.
Buying Guide
What is the correct 240V 30A configuration for my project?
- Choose NEMA 6-30R for 240V single-phase, grounded setups common in welders and air compressors.
- Choose NEMA 10-30R for older, non-grounding configurations that may be present in legacy equipment.
How do I choose between locking vs. non-locking outlets?
- Locking outlets (like Leviton 2620) reduce disconnections in busy workshops or outdoor environments. They require locking plugs.
- Non-locking outlets are simpler and more common for stationary equipment, but less secure in vibration-prone or high-traffic areas.
What mounting options should I consider?
- Flush mount is ideal for clean, low-profile installations in walls or service panels.
- Surface mounting or strap-based designs suit rugged, industrial settings where boxes or enclosures are offset from walls.
What safety and compatibility checks are essential?
- Verify voltage rating, amperage rating, and grounding requirements with your equipment and local codes.
- Ensure the receptacle and plug are compatible with your wall plate and box size.
- Inspect for proper conductor sizing, wire gauge, and secure terminations during installation.

Frequently Asked Questions
- What is the difference between NEMA 6-30R and NEMA 10-30R?
Answer: 6-30R is a 2-pole, 3-wire grounded receptacle for 240V, while 10-30R is typically older, non-grounding and uses 3 wires but with a different configuration. - Can I mix receptacle types in one area?
Answer: Yes, if wiring and codes allow, but ensure each outlet matches the equipment’s plug and safety standards. - Are these receptacles suitable for outdoor use?
Answer: Some are rated for rugged environments; check the product specifications for weather resistance and enclosure requirements. - Do I need a ground connection for all 240V tools?
Answer: Most 240V tools require grounding or bonding as specified by the tool and local electrical code. - Is a locking receptacle necessary for all workshops?
Answer: Not always; locking outlets are beneficial in vibration-prone or high-traffic areas where plugs may loosen. - What installation considerations matter most?
Answer: Wire gauge, terminal type, mounting depth, and compatibility with wall plates and boxes.
