Thanks a bunch Scott! This would definitly be non-resistive due to the fact that 1) there is no R suffix and 2) RFI is not an issue with kerosene heaters! Another key issue is; how good is the insulator at very high voltages? Car plugs have had to contend with ever soaring ignition voltages as super high voltage CD ignition systems have moved into autmotive use. Thus, most car plugs will easily standoff 30kv. But....., Most car plugs are resistive.
