A wall connector on a detached garage is a feeder project wearing an EVSE hat. We still commission the charger. We first decide how power gets across the yard without a voltage-drop surprise.
Key Takeaways
- Conductor and feeder design depends on ampacity, voltage drop, wiring method, terminals, route, and adjustment factors.
- Trench, overhead, or existing-raceway use is a site- and authority-specific decision.
- The load calculation and service review happen before route construction.
- Only documented long, detached, outdoor, trenched, overhead, or otherwise complex routes extend beyond the $1,200–$3,500 typical band up to the $1,200–$4,500 total band; EVSE hardware is separate.
What drives the price
Distance, burial depth and restoration, whether a subpanel in the garage is cleaner than one giant homerun, outdoor ratings, and permit path. Hardware brand does not change that math.
