What type of electrical load is an EV charger?

EV chargers are classified as continuous loads under the NEC (National Electrical Code), meaning they can draw power for more than 3 hours. As a result, circuit sizing must follow the 80% rule (e.g., a 40A charger requires a 50A breaker).

Do Level 2 EV chargers need a 240V power supply?

Yes. Level 2 EV chargers operate on 240V AC and typically require a dedicated circuit rated between 40A and 50A. This is what enables significantly faster charging compared to 120V Level 1 chargers.

Are there safety concerns with multiple EV chargers on one circuit?

Multiple chargers should not share a single circuit unless the charger system explicitly supports load sharing or power management. Without this, overload and breaker trips are likely and unsafe.

How much does it cost to install an EV charger on a standard breaker box?

Typical installation costs range from $300–$1,200, depending on panel capacity, wiring distance, and whether a new breaker or outlet (such as NEMA 14-50) is required. Panel upgrades increase costs.

Can an EV charger be connected inside the meter box?

No. EV chargers must be installed downstream of the main service panel with proper overcurrent protection. Direct connection inside the meter enclosure is not code-compliant in most jurisdictions.

What is the process for getting an electrician qualified to install an EV charger?

Use a licensed electrician familiar with NEC Article 625. Many manufacturers and utilities maintain lists of EV-certified installers. Permits and inspections are usually required.
