Dalek Power Grid Control Panel (Primary Sabotage Panel)

The Dalek City Wall Control Panel is the critical infrastructure target in this event. Susan discovers and slides open the panel, exposing the static-electricity cable that powers the entire Dalek city. The Doctor then smashes the internal glass cover to access the cable, using Susan’s ship key to short-circuit the system. This act triggers localized power failures, including a monitor in the Dalek control room flickering out, directly disrupting their operations. The panel becomes a trap when the Daleks surround the Doctor and Susan, capturing them mid-sabotage.

The small panel with a revolving disc is an additional component of the Dalek power grid, discovered by Susan during the sabotage. The Doctor breaks its glass cover and loops Susan's ship key chain through it, connecting it to the main power cable and further disrupting the system. This secondary panel's tampering amplifies the short-circuit's effect, contributing to the localized power failures in the control room. Its involvement underscores the complexity of the Dalek infrastructure and the Doctor's thorough approach to sabotaging it, ensuring maximum disruption.

The Dalek City Wall Control Panel is the primary target of the sabotage. Susan slides it open, exposing the humming static-electricity cable that powers the entire city. The Doctor smashes its internal glass panel, baring the cable and dropping Susan’s ship key onto it to create a short-circuit. This action triggers a cascade of failures, including the blackout of a control room monitor, proving the success of their sabotage. However, the panel also becomes a trap, as the Daleks detect the disruption and surround the Doctor and Susan, cutting off their escape. The panel’s role is pivotal: it is both the key to their tactical victory and the catalyst for their capture.
