ABSTRACT:
A collapsible metal frame is attachable to the front of a switchboard assembly and allows a circuit breaker to be withdrawn from one of a plurality of vertically stacked compartments and deposited on a pan carried between the open compartment and the metal frame. The circuit breaker may then be lifted above the pan, and the pan removed to allow the circuit breaker to be dropped to ground level. This procedure is reversed to install a circuit breaker into the compartment.
