Hardwired EV Charger Installation
Hardwiring means your charger is wired directly into the circuit instead of plugging into an outlet. It's the route to the fastest home charging speeds and the cleaner choice for an outdoor wall — here's when it makes sense and what to expect.
Hardwired vs. plug-in, in plain terms
A plug-in charger uses a NEMA 14-50 outlet — the same style of socket as an electric range — and caps out around 40 amps of continuous charging. A hardwired charger skips the plug entirely, which is what lets a 48-amp unit run at full speed and stand up better to the weather outside.
Curious about the outlet route instead? Our NEMA 14-50 outlet guide walks through that option.
When hardwiring is the right call
- •You want the maximum 48A charging speed
- •The charger is going outdoors or somewhere damp
- •You want a permanent, tamper-resistant setup
- •Your charger model is hardwire-only (many 48A units are)
How the install goes
The electrician runs a dedicated circuit from your panel to the charger location, fits the correctly sized breaker (a 48A charger needs a 60A breaker and the right gauge wire), mounts and wires the unit, pulls the permit, and schedules the inspection. If your panel is already near capacity, they'll talk you through a panel upgrade or a load-management device first.
FAQ
Do I have to hardwire my charger?▾
If you want the full 48-amp charging speed, usually yes — most 48A units are hardwire-only because a standard NEMA 14-50 outlet circuit tops out at 40A of continuous draw. At 40A or below you can go either way, plug-in or hardwired.
Is hardwired better than a plug-in outlet?▾
For a permanent home charger, hardwiring has the edge: there's no plug to loosen or overheat over time, it's the more weather-resistant choice outdoors, and it unlocks the higher amperage. A plug-in setup wins if you want to unplug and take the charger with you, or swap units easily.
How much does a hardwired install cost?▾
The hardware and labor are similar to a plug-in install; the price is driven by the same things — how far the charger is from the panel and whether the panel needs work. Most straightforward hardwired jobs land in the same range as any Level 2 install. Use the calculator on our home page for a ballpark.
Can I hardwire it myself?▾
We don't recommend it. A 48A circuit on a 60A breaker is serious wiring, it needs a permit and inspection in most areas, and a DIY job can void the charger's warranty and your home insurance. This is a licensed-electrician job.
