Level 1 or Level 2
Level 1 uses a regular 120-volt outlet and adds only a few miles of range per hour. Level 2 uses a 240-volt circuit, like a dryer, and can refill a daily commute in a few hours overnight.
Plug-in or hardwired
A plug-in charger connects to a NEMA 14-50 outlet, which is flexible if you might take it with you. A hardwired charger connects directly to its circuit, supports higher charging speeds, and looks cleaner on the wall. For most homes, hardwired is the better long-term choice.
Sizing the circuit
Chargers are rated in amps, and code sizes the circuit at 125 percent of a continuous load. A 48-amp charger needs a 60-amp circuit, and a 40-amp charger needs a 50-amp circuit. Many chargers can be set to a lower output if your panel is tight.
Tesla, and everyone else
The Tesla Wall Connector is the cleanest choice for Tesla drivers. Many other automakers are adopting Tesla's connector, now standardized as SAE J3400, so check which connector your car uses before you buy. For a mixed garage, a universal charger from ChargePoint or Wallbox is a flexible choice.
What we do
We start with a load calculation, then run the circuit, mount the charger, and handle the permit and inspection. Most installs are done in a single day.
