NEMA L22-30P to P33 AC Power Cord | 30A 277/415V 3-Phase Industrial-Grade Power Cable for Antminer T21 and Bitmain PSU Connection in North American 3-Phase Mining Deployments
The NEMA L22-30P to P33 AC Power Cord is the industrial-grade 3-phase power cable that connects an Antminer T21 (with Bitmain APW17 or APW171 PSU) to North American 277/415V 3-phase distribution. The NEMA L22-30P plug is the standard 30A 3-phase twist-lock connector used in commercial mining facilities running on 277Y wye power; the P33 end is the Bitmain-side connector matching APW17-family PSU inlets.
Rated for 30A continuous current at 277/415V 3-phase — handles the full sustained draw of a single Antminer T21 (~3400W) with plenty of headroom for inrush events. Low-profile ergonomic shape at the plug head keeps the cable run clean in dense rack deployments; fully molded construction eliminates the cable strain failures common with field-assembled cords. Twist-lock retention on the L22-30P end prevents accidental disconnection during fan vibration cycles.
When to Use the NEMA L22-30P to P33 Power Cord
- Antminer T21 deployment in North American 277Y / 480V wye facility — standard 3-phase commercial mining power.
- Replacing a damaged OEM Bitmain T21 cord — fire-rated PSU cord swap in operations and maintenance.
- Bulk facility build-out — provisioning power cords ahead of T21 fleet delivery.
- Container mining deployments — 3-phase distribution at high amperage, twist-lock retention prevents disconnect under vibration.
- Migration from APW12 to APW17 PSU — APW17 uses the P33 inlet, so cord must change with PSU swap.

FAQ — NEMA L22-30P to P33 Power Cord
Q: Will it work with Antminer S21 or T21+?
A: Yes — Bitmain uses the P33 PSU inlet across the APW17 / APW171 family that ships with the T21, S21, S21 Pro, S21 XP, and T21+ generations. The same NEMA L22-30P to P33 cord works across these miners on 277/415V 3-phase power.
Q: What if my facility uses 208V 3-phase instead of 277/415V?
A: Different cord needed. NEMA L22-30P is specifically the 277/415V 3-phase twist-lock. For 208V 3-phase deployments, use the L21-30P or L15-30P variants (different pin orientation). Verify your facility's nominal phase-to-neutral voltage before ordering.
Q: Why 30A vs 20A?
A: T21 at full load draws ~12-14A per phase on 277V. 30A rating provides comfortable headroom for inrush events and accommodates over-clocked configurations. The L22-30P twist-lock is also the dominant facility-side outlet in modern mining datacentres, so 30A is the practical choice.
Q: Bulk pricing for facility deployments?
A: Yes — email contact@lys-sz.com with your fleet size and we'll send case-quantity pricing.
