☄️ Can I Plug 220V Into 240V

US 220v(240v) is really 2-phase power because the two hot lines in your plug are 120v potential from ground, 180deg out of phase. Measuring across the two hot line yields 240v because of the phase difference. This can be configured as 3 wire or 4 wires depending on the appliance needs of a return. .
