Ground Bus Terminal Board

Application

Ground bus terminal boards are a standard component in any distribution or control panel where multiple circuits must share a common protective earth:

• Residential load centers — neutral/ground bus in main and sub-panels
• Commercial switchgear — equipment grounding bar for branch circuit breakers
• Industrial control cabinets — common ground reference for VFDs, PLC chassis, and signal cables
• Renewable energy systems — PV combiner boxes and battery bank ground bus
• Marine electrical panels — ABYC-compliant grounding and bonding bus for vessel wiring
• Telecommunications racks — rack-level grounding bus for servers and active equipment
• Data center PDUs — safety ground bus for multiple IEC 320 outlet sections

Advantage

• All grounds at identical potential — solid bus bar eliminates voltage differences between ground points that cause hum, RF noise, and equipment damage
• High current capacity — tin-plated copper carries 600 A without significant resistance rise — no derating needed in typical panel environments
• Accepts a wide wire range — multi-range screw terminals accept 14 AWG fine-stranded through 4/0 AWG solid in a single model, reducing inventory
• Insulated standoff included — pre-fitted nylon standoffs keep the bus isolated from the metal panel until the single intentional bond point is made
• UL 67 listed — meets North American code requirements for residential and commercial grounding bus in load centers
• No special tools required — standard combination screwdriver handles all screw positions; no torque wrench needed for field installation
