The LG 10,000 BTU 230v Through-the-Wall Air Conditioner with Heat, Model # LT1037HNR has to be plugged into its own dedicated standard 250 V, 3-wire grounding receptacle rated at 20 Amps, 250 VAC protected by a 20 Amp time delay fuse or a 20 Amp circuit breaker. In North America, the terms 220V, 230V, and 240V all refer to the same system voltage level. The reason for the receptacle being rated at 250 V is because for or a time in the early days of electrification, most residential distribution voltage standards were 110/220V. In the late 20s, design standards for equipment mfrs, like NEMA, came into being. Then in the 30s with the REA (a Depression era government program to provide electricity to farms and rural areas) it was bumped to 120/240V and made a national standard. So NEMA, having to now adjust their design standards to match, anticipated the distribution voltage standard possibly increasing again and they settled on 125/250V as a design standard so that they would not have to change again for a long time...^Ivan
