A spark ignitor operates at what voltage AC?

A spark ignitor typically operates at a high voltage AC, usually in the range of 7,500 VAC and higher. The purpose of this high voltage is to create a spark that ignites the fuel-air mixture in heating appliances, such as furnaces or boilers. The electrical energy is transformed into thermal energy by generating a spark, which is necessary for initiating combustion.

While lower voltage levels are used for other purposes in heating systems, spark ignitors require that elevated voltage to ensure a reliable and consistent ignition. Volts below this range may not provide sufficient energy to create an effective spark, which could lead to ignition failure and operational issues in heating equipment.
