Problem
A homeowner wanted dependable overnight charging from a driveway parking spot. Existing panel capacity was tight, and the outdoor path needed weather protection and clean routing. The driveway sits along a shaded side yard prone to wind-driven rain, so mounting height and sealing mattered. The family also wanted to keep a freezer on the same side of the house online during the work.
Site conditions
- Detached driveway adjacent to the house with exposure to rain and snow
- Main panel with limited spare spaces and mixed AFCI/GFCI breakers
- Desired mounting location near a downspout requiring drip loop and sealing
- Family needed evening power left online during install
- Existing landscaping and pavers required careful conduit routing without trip hazards
Diagnosis
Load calculation supported a 50A EV circuit with minor load balancing. Voltage-drop check confirmed conductor sizing needed an upsized copper run for the exterior distance. A combination AFCI/GFCI breaker was selected to meet code and manufacturer guidance. Panel rebalancing moved a basement dehumidifier to another breaker to keep headroom for the EV load and freezer. We also verified that future heat-pump plans could coexist with the new circuit by leaving two adjacent spaces reserved and noting conduit routes for expansion.
