Tesla NEMA Adapter Chart: 5-15, 5-20, 6-20, 10-30, 14-30, 14-50, TT-30 and 10-50
One chart of the NEMA outlets you can charge a Tesla from with the Gen 2 Mobile Connector: how to tell them apart, Tesla's published current and range per hour, and the outlets Tesla's own adapter list leaves out.
| Outlet | Where you find it | Volts / breaker | Tesla max current | Miles per hour (Model 3) | In Tesla's list? |
|---|---|---|---|---|---|
| NEMA 14-50 | Garages, RV parks (50A) | 240V / 50A | 32A | 30 | Yes |
| NEMA 6-50 | Welders, workshops | 240V / 50A | 32A | 30 | Yes |
| NEMA 10-50 | Older electric ranges | 240V / 50A, 3-prong | — | — | No |
| NEMA 14-30 | Newer dryers | 240V / 30A | 24A | 22 | Yes |
| NEMA 10-30 | Older dryers (3-prong) | 240V / 30A | 24A | 22 | Yes |
| TT-30 | RV park pedestals | 120V / 30A | — | — | No |
| NEMA 6-20 | Workshops, dedicated 240V circuits | 240V / 20A | 16A | 15 | Yes |
| NEMA 5-20 | Kitchens, garages (T-slot) | 120V / 20A | 16A | 7 | Yes |
| NEMA 5-15 | Any household outlet | 120V / 15A | — | 6 | Yes (included) |
How to tell the outlets apart
Read the rating printed on the outlet or its breaker first, then count the prongs. The number before the dash is the configuration; the number after it is the amperage.
- 14-50 and 14-30: four prongs, with a round or L-shaped ground pin
- 10-30 and 10-50: three prongs, no ground pin, common in homes built before 1996
- 6-20 and 6-50: three prongs for 240V only
- TT-30: three prongs at an angle, found on RV park pedestals
- 5-15 and 5-20: the everyday household outlet; a 5-20 has one T-shaped slot
14-30 vs 14-50
Both are four-prong 240V outlets. A 14-30 is usually a dryer outlet on a 30A breaker and gives 24A, about 22 miles per hour. A 14-50 on a 50A breaker gives 32A, about 30 miles per hour. The plugs are not interchangeable, so match the adapter to the outlet.
The outlets Tesla doesn't cover
Tesla's Mobile Connector adapter list includes the 14-50 and 6-50 for 50A circuits but no 10-50, and no TT-30 for RV pedestals. Owners with one of these outlets either have an electrician change the outlet or use an independent adapter made for the Gen 2 Mobile Connector.
What decides the real speed
The car sets the charging current from the adapter's signal. Real speed also depends on the car model, temperature and the condition of the wiring. If a plug or outlet gets warm, stop and have the circuit checked.
Frequently asked questions
Which NEMA outlet charges a Tesla fastest with the Mobile Connector?
NEMA 14-50 or 6-50: Tesla lists 32A, about 30 miles of range per hour for a Model 3.
Can I use a NEMA 10-30 dryer outlet?
Yes. Tesla lists a 10-30 adapter at 24A, about 22 miles of range per hour for a Model 3.
Is there a Tesla TT-30 adapter?
Tesla's Mobile Connector adapter list does not include a TT-30. An independent TT-30 adapter for the Gen 2 Mobile Connector lets you use a 30A RV pedestal.
Does Tesla make a NEMA 10-50 adapter?
Tesla's adapter list does not include a NEMA 10-50. An independent 10-50 adapter or a new 14-50 outlet installed by an electrician are the options.
How fast is a normal household outlet?
Tesla lists about 6 miles of range per hour for a Model 3 on a NEMA 5-15 outlet.
