UL 3304 High Voltage Ignition Wire

UL 3304 is a high voltage silicone rubber wire rated 200°C and 10,000V AC under UL AWM Style 3304, produced under UL Follow-Up Service File No. E333030. UL 3304 is the standard ignition lead wire specification for gas burner ignition systems, commercial gas kitchen equipment, and industrial heating equipment where the ignition transformer secondary generates high voltage pulses of up to 10 kV AC to fire the spark electrode. The combination of 200°C silicone rubber insulation and 10,000V AC voltage rating makes UL 3304 the only standard AWM wire construction that can simultaneously withstand the proximity heat of the burner flame zone and the high voltage ignition pulse without insulation breakdown.

UL 3304 bare silicone construction (without fiberglass braid) is the standard specification for open ignition lead routing — where the wire runs directly from the ignition transformer to the spark electrode without passing through conduit or enclosed routing that would require mechanical protection. For enclosed ignition circuit routing where abrasion resistance and mechanical protection are required, see UL 3573 (fiberglass braid). Available in 18 AWG to 10 AWG, RoHS and REACH compliant.
