A 48 A charger works fine in a garage 50 ft or more from the panel, but the circuit has to be planned for the distance. Longer runs add voltage drop, so electricians often upsize the conductors, and the route, conduit and trenching usually cost more than the charger itself. For the EVDANCE EV-ACT5006T, the first decision is whether to run a 60 A circuit for full 48 A charging or a 50 A circuit at 40 A.
Key Takeaways
- Long runs need conductors sized for both current and voltage drop.
- 48 A charging needs a 60 A breaker; 40 A needs 50 A under the 125% rule.
- The route, trench and conduit often cost more than the charger.
- A licensed electrician should design and permit the circuit.
Why Distance Matters for a 48 A Circuit
Every foot of copper has resistance. At 48 A of continuous load, a long run loses more voltage as heat, and the charger sees a little less than the panel supplies. Most electricians design long EV runs so voltage drop stays small, and they do that by choosing a heavier conductor than the shortest run would need. The exact size depends on the wire type, the conduit fill, the ambient temperature and the code edition your area has adopted.
The National Electrical Code treats EV charging as a continuous load, so the breaker must be rated at 125% of the charger current. That gives two common options for this charger.
| Charger setting | Breaker (125% rule) | Connection | Typical power at 240 V |
|---|---|---|---|
| 48 A | 60 A | Hard-wired | about 11.5 kW |
| 40 A | 50 A | NEMA 14-50 receptacle or hard-wired | about 9.6 kW |
| 32 A | 40 A | Hard-wired | about 7.7 kW |
Planning the Route From Panel to Garage
An attached garage on the far side of the house and a detached garage across a yard are very different jobs. Ask your electrician to walk the route with you and price each option.
- Through the house: runs through a basement, crawl space or attic. Often cheaper, but long horizontal runs need support and protection.
- Underground to a detached garage: needs a trench, approved conduit and the burial depth your local code requires. Read our guide to detached garage installation costs.
- Subpanel in the garage: if you also want lights, tools or a second charger, a feeder to a garage subpanel can be more useful than a single branch circuit.
- Lower current: setting the charger to 40 A or 32 A allows a smaller breaker and can reduce conductor size on a marginal run.
Will a Lower Current Setting Be Enough?
For most drivers, yes. At 40 A the charger delivers about 9.6 kW. At a typical 3 to 4 miles per kWh, that is roughly 25 to 35 miles of range per hour, so a night on the charger covers far more than an average daily commute. Our article on whether a 40 amp charger is enough walks through the overnight maths. Choose the full 48 A when you drive long daily distances or share one charger between two cars.
The EV-ACT5006T supports up to 48 A hard-wired, has a 25 ft NACS cable, an IP65/IP66 enclosure and ETL, FCC and CE marks. Its long cable gives you some freedom to mount it near the panel side of the garage and still reach the car.
Frequently Asked Questions
How far can an EV charger be from the electrical panel?
There is no single maximum. Longer runs are allowed when the conductors are sized for current and voltage drop. Your electrician calculates this for your exact distance and wire type.
Do I need a subpanel for a detached garage charger?
Not always. A single dedicated branch circuit can serve one charger. A subpanel makes sense when the garage needs other circuits or a second charger later.
Can I lower the charger current instead of upsizing the wire?
Often, yes. Running the EV-ACT5006T at 40 A or 32 A allows a smaller breaker. The installer must still size the wire for the breaker and run length.
