In a finished garage, the circuit for an EV charger either goes inside the wall cavity or runs on the surface in conduit or raceway. Concealed wiring looks cleanest but can mean cutting drywall. Surface conduit is faster, easier to inspect and easy to change later. Both are acceptable when a licensed electrician uses materials approved for the location and your local code.
Key Takeaways
- Concealed wiring looks cleanest; surface conduit is quicker and easier to change.
- Plan straight, level runs with few bends and protect conduit from impact.
- The breaker and conductors must match the charger setting under the 125% rule.
- Expect a permit and inspection for a new 240 V circuit.
Concealed vs Surface Wiring at a Glance
The best choice depends on how far the charger is from the panel, what is inside the wall, and how much drywall repair you accept.
| Method | Looks | Typical disruption | Good for |
|---|---|---|---|
| In-wall cable | Cleanest, nothing visible | Fishing cable, possible drywall cuts and patching | Short runs on the panel wall or open stud bays |
| Surface metal conduit (EMT) | Neat, industrial | Low, no wall cutting | Long runs, garages with workbenches or impact risk |
| Rigid PVC conduit | Neat, can be painted where allowed | Low | Damp garages and runs that continue outdoors |
| Surface raceway | Slim, low profile | Low | Short drops where the raceway is rated for the conductors |
How to Keep Surface Wiring Tidy
Surface conduit does not have to look like an afterthought. Ask your installer to plan the route before mounting anything.
- Run conduit along the ceiling line or just above the baseboard, not diagonally across the wall.
- Use the fewest bends possible. Fewer bends also make pulling heavy conductors easier.
- Mount the charger so the conduit enters from the bottom or back of the unit, as the installation manual allows.
- Keep conduit away from where car doors, bikes or storage shelves will hit it.
- Paint conduit only with a product suitable for the material, and never paint over labels.

Hard-Wired or Plug-In in a Finished Space
The EV-ACT5006T can be hard-wired for up to 48 A or fitted with a NEMA 14-50P plug for 40 A use. A hard-wired connection avoids a receptacle and plug, which some owners prefer for a permanent installation. A plug-in setup needs a properly rated 14-50 receptacle, often in its own box. Read hardwired vs plug-in chargers for the trade-offs.
Whichever you choose, the conductor size follows the breaker size, and the breaker follows the 125% continuous-load rule: 60 A for 48 A charging and 50 A for 40 A charging.
Inspection and Permits
Most areas require a permit for a new 240 V circuit. Inspectors usually want to see the conduit or cable before it is closed in, so concealed wiring may need an inspection before drywall repair. Surface conduit stays visible, which makes later inspection and changes simpler.
The EV-ACT5006T carries ETL, FCC and CE marks and has an IP65/IP66 enclosure with a 25 ft NACS cable, so it can sit on the wall nearest the panel and still reach most parking positions.
Frequently Asked Questions
Is surface conduit allowed inside a garage?
Yes, surface conduit and listed raceway are widely used in garages. The type and size must suit the conductors and the location under your local code.
Can I run the EV charger cable inside the wall myself?
Wiring a 240 V circuit is work for a licensed electrician in most places, and it usually needs a permit and inspection.
Does conduit reduce charging speed?
No. Charging speed depends on the charger setting, the circuit rating and the car. Conduit only protects and routes the conductors.
