Abstract
A mica board open coil resistance heater assembly includes a mica board subassembly of at least one pair of mica boards, a resistance wire wound around the boards, an electrical connection clip secured to each mica board, wherein each end of the resistance wire is connected to a respective clip. A terminal plate subassembly includes a thermostat, a ceramic two-hole terminal block, and bus wires, the bus wires adapted to be attached to a portion of the electrical connection clip to connect the resistance wire to power. The ceramic two-hole terminal is able to receive push on terminals from power conductors.
