Process Theatre Electrical Infrastructure Junction Box
The junction box (referred to variously as the 'Process Theatre Mains Junction Box' and 'Power Box Outside Process Theatre') serves as the critical electrical infrastructure node in Stangmoor Prison's Process Theatre. It anchors the power systems that maintain containment of the Keller Machine. During the Machine's breach, this junction box explodes violently alongside the power box, shattering the Machine's control collar and triggering widespread chaos. The explosion is witnessed by Brigadier Lethbridge-Stewart, Sergeant Benton, Mike Yates, the Doctor, and the Master, marking the catastrophic failure of containment and the escalation of the crisis.
