No. On a NEMA 14-50 outlet, the EV-ACT5006T runs at up to 40 A — 9.6 kW — not 48 A. The outlet is fed by a 50 A circuit, and because EV charging is a continuous load, the usable continuous current is 80% of the breaker rating: 40 A. The charger’s plug-in configuration is built to exactly that limit. The full 48 A is available only in the hardwired configuration, on a 60 A circuit.
Key Takeaways
- No: on a NEMA 14-50 outlet the ACT5006T runs at 40 A (9.6 kW), not 48 A.
- A 50 A circuit supports 40 A continuously; 48 A needs a 60 A circuit.
- At 40 A the charger still refills most EVs overnight.
- Full 48 A comes from the same unit, hardwired — a configuration change, not a new charger.
Why the Outlet Caps It at 40 A
The arithmetic is the National Electrical Code’s continuous-load rule, and it runs in both directions. A breaker must be rated at 125% of the load it feeds for hours at a time. Turned around, a 50 A breaker may feed a continuous load of 40 A — and 48 A would need 48 × 1.25 = 60 A of breaker, which a 14-50 circuit does not have.
The “50” in NEMA 14-50 names the class of the circuit and receptacle, not the continuous current on offer. Every 48 A-class charger faces the same ceiling on the same outlet, which is why plug-in Level 2 chargers are sold as 40 A units. Our guide to what a NEMA 14-50 outlet is covers the receptacle itself in more detail.
What 40 A on the Outlet Still Delivers
Forty amps at 240 V is 9.6 kW — the output of a full-size home charger, not a compromise trickle. The gap to 48 A shows up only in longer sessions:
| Energy to add | At 48 A hardwired (11.5 kW) | At 40 A on the outlet (9.6 kW) |
|---|---|---|
| 20 kWh | about 1.7 hours | about 2.1 hours |
| 40 kWh | about 3.5 hours | about 4.2 hours |
| 60 kWh | about 5.2 hours | about 6.3 hours |
Times are simple division, before losses and taper. Overnight the outlet is rarely the constraint: eight hours at 9.6 kW moves about 77 kWh, more than the full battery capacity of many EVs. The 48 A setting earns its keep when the parking window is short, not when the car sits all night.
The Outlet Itself Is the Wear Point
A plug-in install puts a receptacle under hours of continuous 40 A load, night after night — which is why the receptacle choice matters:
- Use an industrial-grade 14-50 receptacle. The cheapest outlets are not built for daily continuous duty at this current.
- Plug in and leave it. Repeated plugging and unplugging loosens contacts over time; a home charger should stay connected.
- Outdoors, use an in-use cover that protects the connection while the plug is in place.
- Heat or discoloration at the outlet means stop and have an electrician inspect it. Our article on whether a NEMA 14-50 outlet is a fire hazard explains the warning signs.
How You Get the Full 48 A
The same unit supports it — in its other configuration. A licensed electrician hardwires the charger on a dedicated 60 A circuit and configures it to 48 A, removing the outlet from the chain entirely. That route is worth paying for if you regularly arrive home low and leave again early, or run a large-battery vehicle. The general comparison is in our guide to hardwired vs plug-in chargers.
The Charger in Brief
The EVDANCE EV-ACT5006T is a 48 A Level 2 wall charger (208–240 V, 11.5–12 kW class, 7.6 m NACS cable, IP65/IP66) sold in hardwired and NEMA 14-50P configurations — 48 A on the first, 40 A on the second. If your home already has the outlet and 40 A meets your routine, the portable EVDANCE EV-ACS4005T delivers the same 9.6 kW from that outlet with no installation at all.
Frequently Asked Questions
Can I just set the unit to 48 A while it is plugged in?
No. The charger’s setting must match the circuit it is connected to. The plug-in configuration is a 40 A configuration because the 50 A circuit behind the outlet supports 40 A continuously.
Will the 50 A breaker trip if the charger draws 40 A?
No. Forty amps is exactly the continuous load a 50 A breaker is meant to feed. Tripping at a correct 40 A setting points to a fault or another load on the circuit, and an electrician should look at it.
Does running at 40 A instead of 48 A harm the battery?
No. Both are ordinary Level 2 rates. The car controls the session either way; the only difference is how long the energy takes to arrive.
