The DISCONNECT, TEST,and CONNECT, positions are reached by means of the leveringmechanism.With the breaker solidly positioned on the cassette’s extension railsand levering-in mechanism in the DISCONNECT position, carefullyand firmly push the circuit breaker into the compartment as far as itwill go. The outer (recessed) portion of the circuit breaker faceplateshould align with the GREEN target line (labelled DISC) on the insidetop-left wall of the cassette (Figure 11).Figure 7.
