What gauge of wire is used for an oil burner igniter?

The use of 14 gauge wire for an oil burner igniter is appropriate due to its capacity to handle the electrical current required for proper ignition and operation. Oil burner igniters typically require a specific amount of power to create the necessary spark for combustion. A 14 gauge wire strikes a balance between being robust enough to conduct this current effectively without excessive voltage drop or overheating, while still being manageable enough for installation purposes.

The wire gauge is an important factor in electrical systems, as it determines the wire's current-carrying capacity. Using a gauge that is too small can lead to overheating and potential failure of the component, whereas a gauge that is too large can be unnecessary and less flexible to work with during installation.

In contrast, smaller gauge wires, such as 16 or 18, would not provide adequate current handling for the igniter, while a larger gauge like 12 may be overkill, increasing stiffness and complicating wiring without any real benefit in this scenario.
