240Vonly
240Vonly is a label used for electrical equipment or installations that are designed to operate exclusively on a nominal 240‑volt single‑phase supply and do not support operation at lower voltages such as 120V. Devices described as 240Vonly typically expect a supply near 240V and may not function reliably on 120V or with universal 100–240V input.
Technical requirements include a dedicated circuit and appropriate overcurrent protection, with wiring and connectors rated for
Regional usage varies. In markets with widely available 120/240V service, many heavy appliances such as ovens
