Charger & Circuit Options
- Level 1 (120V): Slow trickle charging from a standard receptacle—good for low daily miles.
- Level 2 (240V): Dedicated circuit for faster daily charging at home (typical 30–60A breaker).
- Receptacle vs hardwired: NEMA 14-50/6-50 receptacle or hardwired EVSE per manufacturer specs.
Load Calculations & Sizing
- Load calc first: We verify service capacity and panel space before specifying breaker and conductor size.
- Continuous load: Chargers are treated as continuous; we size wiring and overcurrent protection accordingly.
- Cable management: Mounting height, cord reach, and parking orientation planned up front.
Permits, Protection & Placement
- Permit & inspection: Typically required for new circuits; we coordinate the process.
- Protection: Breaker/GFCI as specified by listing and local adoption; proper grounding/bonding.
- Location: Indoor garage or outdoor rated equipment; weatherproofing where exposed.
FAQ
Do I need a new panel?
Not always. We calculate your load; if capacity is limited, options include panel upgrades, load management, or smaller charger settings.
How fast will Level 2 charge?
Depends on the vehicle onboard charger and the circuit size. Many drivers recover daily miles overnight on a 40A circuit.
Is a 14-50 receptacle okay?
Often yes for portable EVSEs. Many wall units prefer hardwiring—both approaches must match the manufacturer’s instructions and circuit rating.
How long does installation take?
Most installs are completed in a day, depending on routing distance and panel location.
