A detached garage that doubles as a home office can run an EV-ACT5006T — the charger itself is the easy part. Running the circuit means bringing one dedicated 60 A circuit from the house panel to the garage, sized for the unit’s 48 A continuous draw. The real decision is whether that run is a single charger circuit or a feeder with a subpanel that also powers the office.
Key Takeaways
- Running the circuit means one dedicated circuit from the house panel — 60 A for the EV-ACT5006T at its full 48 A.
- The home office is what can push the job from a single circuit to a feeder and subpanel.
- Daytime charging and office loads share the same feeder, so the load calculation has to count both.
- A lower set current still charges at Level 2 speeds if the supply is tight.
What running the circuit involves
The supply starts at the main panel in the house, because a detached garage rarely has its own service. From there the run crosses whatever sits between the house and the garage. How it crosses — buried or overhead, and in what protection — is your electrician’s call under local code; those details decide much of the quote, so they belong in the site visit.
What is fixed is the sizing. EV charging is a continuous load, so the National Electrical Code sizes the breaker at 125% of the charger’s current:
| EV-ACT5006T configuration | Charging current | Circuit it needs |
|---|---|---|
| Hardwired, full output | 48 A | 60 A dedicated circuit |
| Plug-in (NEMA 14-50P) | Up to 40 A | 50 A circuit with a suitable outlet |
| Set lower at installation | Matched to a smaller circuit | Sized by the same 125% rule |
The unit’s current is set at installation to match the circuit it lands on, so a modest run does not rule the charger out. Our overview of how an EV charger is wired covers what a dedicated circuit means inside the panel.
One circuit, or a subpanel that feeds the office too?
The office is what changes the answer. It needs lights, outlets, heating or cooling on their own circuits. A single dedicated circuit serves the charger and nothing else; a feeder and subpanel serve the charger plus the office — and future loads, such as a second charger.
| Route | What it powers | When it fits |
|---|---|---|
| Single dedicated circuit | The charger only | The garage already has power for the office, or the office runs on an existing supply |
| Feeder + garage subpanel | The charger and separate office circuits | The garage has no supply yet, or the office is a real workspace with its own loads |
If the garage already has a subpanel with spare capacity, the job can shrink to a short circuit run from that panel. If it has only a lighting circuit, that is not enough for a charger — a load calculation gives the answer. Deciding where the charger goes also shortens the run.
Charging during the workday
An office garage charges at office hours, not overnight. Daytime sessions overlap the office’s own loads on the same supply, so the feeder must be sized for charger and office together — that sum is what the load calculation is for. If the sum is tight, the unit can be set to a lower current: it still charges inside the Level 2 band the U.S. DOT puts at 7–19 kW, adding roughly 10–20 miles of range per hour.
The charger on the end of the run
The EV-ACT5006T is a 48 A NACS Level 2 wall charger (11.5–12 kW on 208–240 V) with a 7.6 m cable, rated IP65/IP66 for an exposed garage wall, and offered hardwired or with a NEMA 14-50P plug. Hardwired suits a permanent office-garage install at the full 48 A; the plug-in version works where a suitable 240 V outlet already exists in the garage. See also EVDANCE’s residential charging page.
Frequently Asked Questions
Can the charger share the garage’s existing circuit?
No. A charger needs its own dedicated circuit, sized at 125% of its current. Garage lighting and outlet circuits are not built for a continuous 48 A load, and no electrician will sign off on sharing one.
Does a home-office garage always need a subpanel?
Only when the office needs its own circuits from the same run. If the garage already has a supply with spare capacity, a dedicated charger circuit from the existing subpanel may be all that is needed. The load calculation decides.
How far does the cable reach once the unit is mounted?
The EV-ACT5006T’s cable is 7.6 m (25 ft). Mount the unit on the wall the car parks beside, close to the charge port’s usual position, so the cable reaches without stretching across the garage.
