De Dietrich Ignition Cable 200004780, 550 mm length (x2), 200004780

This ignition cable, branded De Dietrich, is supplied as a pair of 550 mm lengths. Manufacturer codes: 200004780 and 336.292.003. The catalogue category is Cables. Ignition cables of this type carry the high-voltage spark from the ignition transformer to the ignition electrode(s) during the start-up sequence. The spark must be reliable and properly timed to ignite the air-fuel mixture. Such cables are selected by length, connector type (boot, spade, or screw terminal), and insulation temperature class—since they run close to the combustion head and can be exposed to radiant heat. When replacing, verify that the connector matches both the transformer output and the electrode terminal; a loose or corroded connection can cause intermittent ignition or lockout. Because the cable carries pulsed high voltage, the insulation must be intact along its entire run—any crack or abrasion can allow flashover to ground. The pair supplied here may serve dual-electrode systems where one electrode provides the spark and the other serves as flame sense, or where two spark electrodes are used for redundancy. Always compare the original cable’s length and terminal shape to the replacement; a cable too short may strain the terminals, while one too long can sag into hot surfaces.
