- Max load (at rating)
- 250 V × 15 A = 3,750 VA
- Continuous (80%)
- 3,000 VA
Load figures are the arithmetic of the device rating at unity power factor. Continuous loads (3 hours or more) are limited to 80% of the circuit rating per NEC 210.19/210.20 — and the branch circuit behind the receptacle comes from the load calculation and conductor sizing, not from the plug face.
Where you meet it
240 V equipment, window AC. Family 6 overall: welders, ev charging, 240 v equipment (6-50). Blade geometry keys the voltage family physically: a plug from a different voltage class will not enter this receptacle.

Common questions
What is the difference between 6-15R and 6-15P?
The letter is the device: 6-15R is the receptacle (outlet), 6-15P is the plug on the cord. Both share the same configuration — 250 V, 15 A, 2-pole 3-wire grounding.
Does NEMA 6-15 have a neutral and a ground?
No neutral — the 250 V rating means the circuit runs line-to-line with no neutral. It carries an equipment grounding conductor (the extra wire beyond the poles).
