1. The open electrical panel
Open the panel door — not the interior cover, just the door — and photograph the full breaker layout straight on, close enough to read the numbers on the breakers. Include the main breaker at the top, which shows your service size.
2. The charger location
Photograph the wall where you want the charger, standing back far enough to show the surrounding area and where the vehicle parks. This shows the mounting surface and any obstructions.
3. The route between them
A wide shot showing the path from the panel toward the charger location. This is where a short walkthrough video is even better than a photo.
4. Optional: the walkthrough video
Start at the panel, narrate briefly, and walk slowly toward the charger location showing walls, ceilings, and floors. Thirty to sixty seconds is plenty, and it answers questions a photo cannot.
