What are the electrical requirements for the charger?

The electrical requirements of a charger depend on how much power it’s meant to deliver. Almost all Level 2 chargers require a 240 volt outlet similar to a major appliance like your dryer or oven. The second thing to consider is the amperage required for the circuit. Some Level 2 chargers require as little as 20 amps while others like Tesla chargers can require up to 100 amps. We often recommend installing the charger on a 50 amp circuit and wiring to allow for additional power needs in the future, even if it only calls for 20-40 amps.
