It depends on the service size and on whether the two loads can run at once. A 32-amp charger is a continuous 7.68 kW load at 240 V; an electric dryer is also a large 240-volt load. On many 200-amp services the pairing fits a load calculation; on many 100-amp services it does not, or it fits only with a lower charger setting or load management.
This is the coincident-use version of the EV-plus-dryer question. If you charge in the evening while laundry runs, the electrician should not treat the dryer as something that never overlaps the charger.
| Step (2023-style optional method, educational) | Result |
|---|---|
| General lighting at 3 VA/ft² | 5,400 VA |
| Small-appliance and laundry circuits at 1,500 VA each | 4,500 VA |
| General load including listed nameplates and EVSE | 22,980 VA |
| First 10 kVA at 100%, remainder at 40% | 15,192 VA |
| Larger of the heating or cooling values entered, at 100% | 4,000 VA |
| Calculated load | 19,192 VA · 80.0 A at 240 V |
| Compared with this walk-through’s service rating | 80.0 A is under a 100 A rating by 20.0 A |
Educational walk-through of the optional dwelling-unit method structure in NEC 2023 220.82. Not a permit calculation. 220.82(C) heating/cooling selections can be more involved than “the larger of two numbers,” especially with heat-pump backup strips.
On a 100 A service this walk-through is about 80.0 A — tight enough that a 40 A or 48 A charger, or an electric range on top, can change the answer. The 200-amp version of this pairing is on the dedicated 200-amp page. A listed load-management device can pause the charger while the dryer runs, which is a different solution from a heavy-up. Use the calculator.
