Ways to save in Napa
- Go straight to 200 amp — the incremental cost over 150 is small and you will not repeat the job.
- Bundle EV charger, surge protector and any new circuits into the same permit and visit.
- Check for utility and federal electrification rebates before you sign.
- Get three bids; panel pricing varies more between electricians than almost any other trade.
- Ask about keeping the panel in its existing location to avoid relocation cost.
