Copper Grounding Bus Bars (CGB Series)
Penn-Union Copper Grounding Bus Bars (CGB Series) provide a reliable, low-impedance grounding solution for electrical distribution systems, data centers, telecom infrastructure, and industrial facilities. Manufactured from high-conductivity copper, these grounding busbars create a centralized bonding point for equipment grounding conductors while helping safely dissipate fault current.
Commonly installed in main switchgear rooms, transformers, PDUs, UPS systems, and generator transfer equipment, CGB grounding bus bars help maintain a stable grounding reference for critical electrical systems.
Available in 2-inch and 4-inch widths with multiple lengths, Penn-Union copper busbars provide flexible grounding capacity. Narrower bars are ideal for panel boards, telecom rooms, and smaller enclosures, while wider bars support main electrical infrastructure where larger conductors and multiple grounding connections are required.
Copper Grounding Bus Bars for Data Centers
Copper grounding bus bars play a critical role in maintaining reliable grounding and bonding throughout modern data center infrastructure, helping protect sensitive IT and networking equipment while maintaining power quality.
- • Main switchgear grounding where the facility grounding reference is established
- • Transformers and PDUs (Power Distribution Units) that terminate equipment grounding conductors
- • UPS systems and static transfer switches requiring clean grounding to reduce electrical noise
- • Server cabinet and rack row distribution panels providing common grounding points for rack PDUs
- • Overhead busway tap boxes and plug-in units supplying power to high-density server racks
- • Telecommunications grounding systems (TGB / TBB) installed in MDF and IDF rooms following TIA-942 data center standards
These grounding busbars help create a low-impedance grounding network that supports stable power delivery and protects mission-critical data center equipment.
