Level 1 charging is defined by which supply characteristics?

• A. 120V Single-Phase Supply, Typically 14-16 A
• B. 240V Single-Phase Supply
• C. DC Supply at 400V
• D. 3-Phase 480V Supply

Answer: (A)

Level 1 charging is defined by using a standard household AC supply: a 120-volt single-phase circuit. This is the everyday outlet most homes have, typically on a 15-amp circuit (often around 14–16 amps in practice). At 120 volts, drawing about 14–16 amps yields roughly 1.7–1.9 kilowatts of charging power, which makes Level 1 the slowest form of charging. It relies on a basic EVSE and does not require high-voltage or complex wiring. The other supply configurations describe higher-power setups: a 240-volt single-phase supply corresponds to Level 2 charging, which provides faster charging with higher voltage and current; a DC supply at 400 volts is a DC fast charging scenario; and a 3-phase 480-volt supply represents a high-power industrial or commercial setup not used for Level 1.
