Every residential electric ranges I've ever checked is dual-marked for 208V and 240V. At 208 volt supply, the resistive elements pull fewer amps, so with lower amps and volts, you get noticeably less output power (takes and extra minute to boil a pot of water). But everything still works.
While single family homes are almost always supplied by 120/240 split phase, there are millions of Multi-family residential homes (condos and apartments) in the country, and the majority are supplied with 208v three phase power, with each individual unit getting 2 of three phases plus the neutral. Even electric water heaters and most AC compressors that I've checked also seem to be dual rated (208/240V). Electric car chargers are also agnostic. /wk William Korthof 714.875.3576 Sustainable Solutions #956904 > I feel sort of stupid asking this, but it has never come up for me before: > > > > I have inherited an off-grid install gone-wrong.
