Wayne 13286 Pair Electrode /Insulator Model E & M (Set of 2)Wayne 13286 pair electrode insulator model E&M (Set of 2) The electrode provides the electric spark to ignite the fuel nozzle. The electrode is a metal rod that is threaded on one end and bent or curved on the other end. Two of these rods are paired and curved toward each other so that electrical arcing will occur at and only between the tips of the rods. The electrodes are inserted through a ceramic insulator. The insulator prevents arcing between
