How Long Does EV Charger Installation Take?
The installation itself usually takes half a day. But there's a permit and inspection process around it that adds a few days to the full timeline. Here's the complete picture.
Most Tulsa EV charger installations take 2 to 4 hours of actual work. That covers a licensed electrician pulling a dedicated 240V circuit from your panel to the garage and mounting the charger. Plan for a half-day appointment. What people don't always account for is the permit process before and the inspection after — that part adds several days to the total timeline, though none of it requires you to be home for long.
The Full Timeline
| Step | Typical Duration | Notes |
|---|---|---|
| Get quotes and schedule | 2 to 5 days | Good Tulsa electricians book a few days out |
| Permit pulled by electrician | 1 to 3 business days | City of Tulsa processes quickly for EV installs |
| Actual installation | 2 to 4 hours | Longer for panel upgrades or detached garages |
| Electrical inspection | 2 to 5 business days to schedule, 30 min to inspect | Electrician handles scheduling |
| PSO rebate processing | 4 to 8 weeks | Submit application within 45 days of purchase |
What Makes Installation Take Longer
A simple attached garage next to a newer 200-amp panel is the fastest scenario. A few things push the job toward a full day:
Panel upgrade needed
If your home has a 100-amp panel that's already loaded — common in older Midtown and South Tulsa neighborhoods — adding a 50-amp EV circuit isn't always possible without a panel upgrade. Upgrading from 100 to 200 amps adds 3 to 5 hours of work and may require a separate PSO service upgrade appointment. That can extend the project to two separate days. See the panel upgrade guide for specifics.
Detached garage
Running conduit underground from the main panel to a detached garage is more labor-intensive. Expect a full day for detached garage installs, especially if trenching is involved. The permit process is the same, but the inspection scope is larger.
Long conduit runs
If your panel is on the opposite end of the house from the garage, the electrician has a longer run of conduit to manage — through attic space, along exterior walls, or through the garage ceiling. Each 10 feet of extra conduit adds time and material cost.
Complicated panel location
Some Tulsa homes have the panel in an awkward spot — inside a closet, in the utility room at the back of the house, or in a finished basement. These don't necessarily add hours, but they slow down the work compared to a panel in the garage or near it.
The Permit and Inspection Process
Your electrician handles both the permit application and inspection scheduling. You don't need to do anything except be home for the inspection.
The City of Tulsa's electrical inspection for an EV charger installation typically takes 15 to 30 minutes. The inspector checks that the circuit is properly sized, the breaker is correctly rated, the wiring is to code, and the charger is mounted correctly. If everything passes — which it will, if your electrician is licensed and competent — you're done.
If something needs to be corrected, the electrician fixes it and schedules a re-inspection. This is uncommon with licensed contractors but does happen occasionally.
Planning Around the PSO Rebate Deadline
PSO requires you to submit the rebate within 45 days of the charger purchase date. That's not a lot of time if you're slow getting started. Here's how to make sure you don't miss it:
- Get quotes before you buy the charger. Know your electrician and your timeline.
- Buy the charger. Mark day 45 on your calendar immediately.
- Schedule the installation within the first week after purchase.
- Submit the PSO rebate application as soon as the charger is purchased — you don't have to wait for installation or inspection.
The 45-day window is tighter than it sounds. If you buy the charger and wait two weeks to schedule the electrician, you're already one-third through the window.
Frequently Asked Questions
Generally yes — the electrician needs access to your panel and garage, and may have questions during the job. Most installations are done in a single visit, so plan to be available for a half-day block.
A panel upgrade combined with EV charger installation typically takes one full day — sometimes spread across two visits if PSO needs to upgrade the service meter. Budget the full day and treat it as a single project.
Some Tulsa electricians can pull same-day permits, but this isn't guaranteed. Many prefer to pull the permit a day or two ahead and schedule installation once it's approved. Ask your electrician during the quote process.
You can use the charger as soon as installation is complete — you don't need to wait for the inspection. The inspection confirms the work meets code but doesn't change whether the charger functions. That said, your electrician may want to run a brief test before leaving anyway.
