Abstract
A support insulator for an open coil electric heater includes an insulator body having at least one coil support portion and plate attachment slots. The support insulator has an arm extending from the insulator body, the arm having a slot on an end thereof. Depending on the mounting of the support insulator, the slot can receive a resistance wire as a portion of a coil break-turn, a wire as part of a coil section, a part of a lead wire, or a part of a run of resistance wire that is not a coil break-turn or coil section.
