Bus Design
CENTERLINE bus design means more current carrying capacity per section.
• Standard vertical bus is rated twice the industry norm: 300 A above and 300 A below the horizontal bus for an
effective 600 A capacity per section
• Allows more flexibility for field changes without exceeding vertical bus rating
• Sections available in back-to-back design with separate front and rear vertical bus for maximum loading capacity
• Continuous bus bracing provides more uniform support than commonly used standoffs
Vertical wireway contains no control or power terminations making cable installation safer. For added safety, a
permanent barrier separates the vertical wireway from units. Automatic shutters available to immediately isolate vertical
bus when unit is removed.
Computerized fastening system used in the assembly of horizontal to vertical bus connection:
• reduces periodic maintenance
• minimizes exposure to hazardous voltage
Dedicated plug-in ground bus is part of a solid grounding system.
