What is the typical voltage rating for ignition transformers in oil burners?

The typical voltage rating for ignition transformers in oil burners is usually between 10,000 to 15,000 volts. This range is essential because the ignition transformer needs to produce a sufficiently high voltage to create a reliable spark that ignites the oil. An adequate voltage is necessary to overcome the insulation resistance of the burner components and ensure consistent ignition, which is crucial for safe and efficient burner operation.

While higher voltage ratings exist, as indicated in other choices, they are generally not required for typical residential and commercial oil burner applications. Therefore, the voltage range chosen aligns with standard operational requirements without excessive voltage, which could lead to unnecessary wear or potential safety hazards in the burner system. This focus on practical application highlights why the specified range is prevalent in industry practices.
