A 240 V entry is useful when the equipment is labelled for a 240 V single-phase supply, but the supply arrangement, conductor configuration, and actual measured voltage still control compatibility.
A 240 V nominal input may be line-to-line in a split-phase arrangement or a line-to-neutral value in another system. Read the equipment label and measure the supply rather than inferring the topology from the number alone.
At PF 1.0, a 7.2 kW EVSE estimate is 30.00 A. At PF 0.8, the same real power would be 37.50 A.
A nominal 7 kW charger is not guaranteed to draw exactly one fixed current. Vehicle acceptance, EVSE pilot settings, supply voltage, connector temperature, and installation limits can reduce the actual charging power. The same principle applies to electric showers, ovens, heat pumps, and HVAC equipment.
Using a 240 V single-phase equation for a 240 V three-phase L-N input, or assuming a 240 V receptacle has the same earthing and neutral arrangement everywhere, can create an unsafe design assumption. Follow the nameplate, supply diagram, and local installation requirements.
No. It may be line-to-line in a split-phase supply or line-to-neutral in another configuration. Confirm the actual conductors and equipment label.
The vehicle or EVSE can limit power, and actual voltage may differ from nominal. PF and control behaviour can also change the input current.
Only after accounting for PF, starting behaviour, duty cycle, and the actual supply. The same voltage does not mean the same current waveform or operating profile.
Check voltage notation, nameplate current, conductor arrangement, continuous duty, voltage drop, protection, and the applicable installation rules.
