General Electric | SB422SGD4GI | Bus Plug | 225A | 4-Pole | 600V

General Electric SB422SGD4GI Bus Plug is a purpose-built, high-capacity connection component designed for GE switchgear. Built for reliability in maintenance, retrofit, and replacement projects, this 4-pole bus plug delivers precise compatibility wherever matching specs matters most.

• Amperage: 225A
• Poles: 4-Pole
• Voltage: 600V
• Part number: SB422SGD4GI

This bus plug is ideal when you need a trusted GE part that interfaces cleanly with existing gear, preserving protection schemes, contact reliability, and system integrity during upgrades or replacements. It is suitable for routine maintenance, equipment retrofits to newer configurations, and straightforward replacements where exact GE compatibility is required.

Why this matters

Using the SB422SGD4GI ensures your bus connection aligns with the original design intent, reducing the risk of mismatched fittings or improper contact that can lead to downtime or performance issues. The 4-pole design supports robust power distribution across multiple circuits, while the 600V rating suits a wide range of industrial and commercial electrical environments.

Use cases

• Maintenance on GE switchgear that relies on the SB422SGD4GI configuration
• Retrofits to upgrade bus arrangements to a 4-pole, 225A, 600V setup
• Replacement when stocking spare parts for critical equipment uptime

Fit and compatibility are essential. The product notes emphasize that the part number is the best reference for compatibility and that you should confirm fit and ratings before ordering to avoid mismatches.

Who should consider this

• Plant engineers and facilities managers overseeing GE switchgear
• Electrical maintenance teams performing retrofits or replacements
• Electrical contractors specifying compatible components for GE-based systems

Practical tips for selection and installation:

• Cross-check your equipment’s rated voltage and current with 600V, 225A and a 4-pole configuration to ensure a seamless fit.
• Use the SB422SGD4GI part number as the primary reference during procurement to maximize compatibility.
• Keep a dedicated spare for critical lineups to minimize downtime during scheduled maintenance or unexpected failures.
• Always follow established safety procedures, isolate power, and use appropriate PPE during installation or replacement.
