Abstract
The following specification describes a thin walled insulating boot formed of a thermoplastic molding material and attached by means of the circuit breaker in encircling relationship to the open end of the breaker. The boot prevents ionized gas created when the circuit breaker is tripped from completing a circuit path to adjacent metal portions. The boot walls extend past the open end of the breaker and a back wall spaced from the open end of the circuit breaker defines a chamber enabling expansion of the ionized gas.
