Electric vehicles (EVs) need chargers, and phones need plugs. Installing one at home takes time, but not as much as you might think. Let’s break down the process.
What Affects EV Charger Installation Time?
Three things decide how long your installation takes:
- Your Electrical System
Older homes often need panel upgrades. A 100-amp panel might not handle a 50-amp EV charger. Upgrades add 1–3 days. - Charger Type
Plug-in chargers (like a toaster) take less time. Hardwired chargers (like a ceiling fan) need more work. - Permits
Some cities approve permits in a day. Others take weeks. Check Local requirements before starting.
Expert Tip: Ask your electrician to inspect your panel first. Avoid surprises.

Mount the unit, connect the wires, and test it.
EV Charger Installation Timeline (Table)
| Stage | Time Required |
|---|---|
| Site Inspection | 1–2 hours |
| Permit Approval | 1–14 days |
| Electrical Panel Upgrade | 1–3 days |
| Charger Installation | 4–8 hours |
| Final Inspection | 1–2 hours |
Note: Total time ranges from 2 days to 3 weeks.
Why Professional Installation Matters
I once saw a homeowner try DIY. They wired the charger backward. It fried the circuit. Professional electricians follow codes like NEC Article 625. They ensure safety.
For example, hardwired chargers need a GFCI breaker. Plug-in chargers need a dedicated outlet. Get it right the first time.
How to Choose the Right Electrician
- Check licenses (C-10 in California).
- Ask about EV experience.
- Read reviews on our San Bernardino Installer Directory.
Warning: Avoid electricians who say, “Permits aren’t needed.” They’re cutting corners.
Common Delays in EV Charger Installation
- Permit Delays
Cities like San Diego take longer during busy seasons. - Supply Issues
Breakers or wiring might be backordered. - Weather
The rain stops outdoor work.
Plan for these. Add a buffer week.
Can You Speed Up the Process?
Yes.
- Pre-Apply for Permits: Some cities let you apply online.
- Buy the Charger Early: Ensure it’s in stock.
- Schedule Inspections Fast: Ask your electrician to book them.
