A NEMA 14-50P is the plug fitted to the cord of many Level 2 EV chargers. The “P” stands for plug: it is the four-prong end you hold in your hand, rated at 50 amps and 125/250 volts. It mates with a matching wall receptacle, the 14-50R, and on a charger it signals a plug-in unit designed for a 50-amp circuit.
Key Takeaways
- A NEMA 14-50P is the four-prong plug on a charger’s cord; “P” means plug, and the wall half is the 14-50R.
- It is rated 50 A at 125/250 V, and a charger on it draws at most 40 A as a continuous load.
- The plug fits only a 14-50R — a mismatch is a stop sign, never something to force.
- The charger’s own rating, not the plug, sets how much current it actually draws.
How to Recognise a 14-50P
NEMA names follow a pattern: the first number is the configuration series, the second is the current rating, and the letter says which half of the connection you are looking at. Four metal contacts give the 14-50P its distinctive face.
| Feature | What you see on a 14-50P |
|---|---|
| Hot contacts | Two straight vertical blades, side by side |
| Neutral contact | One straight blade, centred below the hot blades |
| Ground contact | One U-shaped or round pin at the top |
| Rating | 50 A, 125/250 V, stamped on the plug body |
| Size | Much larger than a household plug; it will not enter a standard wall outlet |
The fixed blade pattern means a 14-50P enters only a 14-50R. A plug that does not match the receptacle in front of you is a stop sign, not a challenge: never force or modify one. Our guide to what a NEMA 14-50 outlet is shows the wall side of the same connection.
14-50P and 14-50R: Two Halves of One Connection
| 14-50P (plug) | 14-50R (receptacle) | |
|---|---|---|
| Where it lives | On the charger’s cord | In the wall, on the circuit |
| Who supplies it | The charger manufacturer | The building owner, usually via an electrician |
| What it carries | Prongs that insert | Slots that receive them |
| What it tells you | The charger is a plug-in model | The circuit is rated 50 A |
The two halves are sold and installed separately: the charger maker answers for the plug, the property side for the receptacle and its wiring. The comparison in NEMA 14-50 vs 6-50 vs 5-15 shows how this pattern differs from other common outlet types.
What a 14-50P on a Charger Tells You
- The circuit size. The charger expects a 50 A circuit. Under the NEC, EV charging is a continuous load, so the breaker is sized at 125% of the charger’s draw — a charger on this plug charges at up to 40 A, not 50 A.
- The charging class. At 240 V, 40 A delivers up to 9.6 kW, squarely in the U.S. DOT’s Level 2 band of 7–19 kW and about 10–20 miles of range per hour.
- The charger’s own setting matters. A 32 A model draws 32 A through the same plug; the plug rating is the ceiling of the connection, not the charger’s appetite.
- Portability. A plug-in charger can be unplugged and taken along — to a new home, or to any site that already has the matching receptacle.
EVDANCE Chargers That Ship With a 14-50P
Three EVDANCE portable chargers state a NEMA 14-50P plug in their listings. The EV-ACS4005T is a 40 A NACS portable, adjustable at 16/24/32/40 A for 9.6 kW, IP66, with a 25 or 28 ft cable. The EV-AC04001U is the 40 A J1772 equivalent at 9.6 kW, IP66, with a 25 ft cable. The EV-ACS3210T is a 32 A NACS portable at about 7.7 kW, adjustable in six steps from 10 to 32 A, IP66. The wall-mounted EV-ACT5006T is also offered in a plug-in 14-50P version alongside its hard-wired option.
Frequently Asked Questions
Is a 14-50P the same plug RVs use?
The 50 A hookup at most campgrounds is a NEMA 14-50 receptacle, so a charger with a 14-50P plug fits it mechanically. Whether a site allows EV charging on its hookups is that site’s own rule — ask before you rely on it.
Can a 14-50P plug go into a 14-30 dryer receptacle?
No. The 14-30 is a different configuration with a different rating, and the blade pattern is deliberately different so the two cannot mate. If the receptacle at your parking spot is a 14-30, you need a charger and circuit arrangement specified for it, not force or a modified plug.
Does a 14-50P mean the charger draws 50 amps?
No. 50 A is the rating of the plug and its circuit. EV charging is a continuous load, so a charger on a 50 A circuit draws at most 40 A — and smaller models draw less.
