Abstract
A residential circuit breaker design provides heat sink facility to the current carrying members within a thermoset plastic base. A thermoplastic plastic cover is ribbed internally to minimize contact between the interior of the cover and current carrying components. The thermoplastic cover results in a substantial savings in material costs since the thermoplastic waste material is recoverable and re-useable.
