Level 1 vs Level 2 EV Chargers: What Santa Clarita Homeowners Need to Know
If you're planning to install an EV charger in your Santa Clarita home, one of the first decisions you'll face is choosing between Level 1 and Level 2 charging. Both will charge your vehicle — but the difference in speed, installation requirements, and day-to-day convenience is significant enough that for most homeowners, it's not really a close comparison.
Understanding what each option actually involves helps you make the right choice based on your driving habits, your home's electrical system, and how you plan to use your EV over the long term.
Bolt Blitz Electric, a licensed C-10 electrical contractor serving Santa Clarita and Los Angeles County, installs both Level 1 outlet upgrades and full Level 2 charger systems. Here's what you need to know before deciding.
Level 1 vs Level 2 at a Glance
Before diving into the details, here's a side-by-side comparison of the two options across the factors that matter most to Santa Clarita homeowners:
| Feature | Level 1 | Level 2 Recommended |
|---|---|---|
| Voltage | 120 volts | 240 volts |
| Range Added Per Hour | 3 – 5 miles | 20 – 40 miles |
| Full Charge Time | 24 – 50+ hours | 4 – 12 hours |
| Installation Required | None (uses existing outlet) | Dedicated 240V circuit |
| Permit Required | Usually no | Yes |
| Panel Evaluation Needed | No | Yes |
| Typical Cost | Minimal | $1,500 – $3,000+ |
| Best For | Low mileage, backup charging | Daily use, most homeowners |
What Is a Level 1 EV Charger?
A Level 1 charger uses a standard 120-volt household outlet — the same type used for lamps, phone chargers, and small appliances. It's the simplest charging option available, requiring no additional electrical installation in most cases. You plug the charger into the outlet, connect it to the vehicle, and charging begins.
Charging Speed
Level 1 charging adds approximately 3 to 5 miles of range per hour. For a vehicle with a 250-mile battery range that is fully depleted, a complete charge from empty could take 50 hours or more. For drivers who cover 30 to 40 miles per day and can leave the vehicle plugged in every night, Level 1 may just barely keep pace with daily driving needs — but there's little margin for days when the vehicle comes home with a lower charge than usual.
When Level 1 Makes Sense
Level 1 charging is practical for Santa Clarita homeowners who drive short distances daily and can charge overnight consistently without exception. It also works as a backup option when a Level 2 charger isn't yet installed, or for plug-in hybrid vehicles with smaller battery packs that don't require as much charge time. For most homeowners with a primary EV and regular driving needs, Level 1 is a temporary solution rather than a permanent one.
What Is a Level 2 EV Charger?
A Level 2 charger operates on a 240-volt dedicated circuit — the same voltage used by electric dryers and ovens — and delivers significantly more power than a standard outlet. It requires professional installation, a dedicated circuit, and in most cases a permit and inspection. Per NEC Article 625, EV charging equipment must be installed on a dedicated circuit and meet specific safety requirements. This is the charger type installed in the overwhelming majority of Santa Clarita homes where daily EV use is the norm.
Charging Speed
Level 2 charging adds approximately 20 to 40 miles of range per hour depending on the charger's output and the vehicle's onboard charger capacity. Most vehicles reach a full charge overnight — typically in 4 to 12 hours — which means the car is ready every morning regardless of how depleted it was the night before. This is what makes Level 2 the practical standard for daily EV ownership rather than an upgrade.
Electrical Requirements
Level 2 chargers are classified as continuous loads under the NEC — equipment that draws full current for extended periods during every use. Per NEC Article 210, continuous loads must be calculated at 125 percent of their rated current when sizing the circuit and breaker. Common circuit configurations are 40-amp, 50-amp, and 60-amp dedicated circuits, depending on the charger's rated output. Your electrical panel must be evaluated before installation to confirm it has sufficient remaining capacity to support the new circuit without requiring an upgrade.
Installation Differences
Level 1 Installation
Level 1 requires no dedicated electrical work in most cases — it uses an existing 120-volt outlet in the garage or wherever the vehicle is parked. If the outlet doesn't exist where it's needed, having one added is straightforward and relatively inexpensive. No permit is required in most cases for simply using an existing outlet, and no panel evaluation is needed unless an outlet is being added to a circuit that may be at capacity.
Level 2 Installation
Level 2 installation involves running a new 240-volt dedicated circuit from the electrical panel to the charger location, installing an appropriately sized breaker, mounting the charger unit, and verifying all connections and grounding. In Los Angeles County — including Santa Clarita — this work requires a permit and a post-installation inspection. For Santa Clarita-area installations, permits are typically processed through the LA County EPIC-LA system.

SCE and Utility Considerations
For some Level 2 installations in Santa Clarita, Southern California Edison may need to be involved — particularly when the existing service capacity isn't sufficient to support the added load even after a panel upgrade. SCE involvement adds a step to the project timeline and should be factored into planning when a service upgrade is identified as a possibility during the initial evaluation.
Not every installation requires SCE coordination. Many Santa Clarita homes have sufficient existing service to support a Level 2 charger circuit without utility involvement. The load calculation performed as part of the pre-installation evaluation identifies whether this step will be needed.

For the majority of Santa Clarita homeowners, the answer is Level 2. Here's how to think about it:
- Level 1 is appropriate if you drive fewer than 30 miles per day consistently, have a plug-in hybrid with a small battery, or need a temporary charging solution while a Level 2 installation is being planned and permitted
- Level 2 is the right long-term choice if you drive a primary EV, have daily mileage that varies, want the reliability of a full charge every morning, or plan to keep the vehicle for several years
The upfront cost of Level 2 installation is real — but the convenience of waking up to a fully charged vehicle every day, without managing charging windows or worrying about overnight charge time, is what makes it the practical standard for daily EV ownership. Most homeowners who start with Level 1 upgrade to Level 2 within the first year.
Why Professional Installation Matters for Level 2
Level 2 EV chargers require proper installation to ensure safety, code compliance, and reliable long-term performance. Improper installation creates real risks that don't always surface immediately but develop into significant problems over time — overloaded circuits from incorrect load calculations, failed inspections requiring work to be redone before the permit closes, unsafe wiring from improperly terminated connections, and liability issues from unpermitted work that surfaces during home sales. Working with a licensed C-10 electrical contractor ensures the installation is done correctly the first time, passes inspection, and delivers the charging performance the system is rated for.
