Equipotential Bonding Busbars for Medical Locations

Supporting safer, compliant electrical infrastructure across Group 1 & Group 2 medical locations

Equipotential Bonding Busbars (EBBs), also referred to as Earth Bonding Bars or Earth Reference Bars (ERBs), support supplementary protective bonding within medical locations, helping to limit touch voltages and reduce the risk of electric shock to patients. 

An EBB provides a central connection point for relevant exposed and extraneous conductive parts, helping to equalise potential differences within the patient environment. 

Bender UK offers a range of EBBs designed for different medical environments and applications, supporting the requirements and guidance for Group 1 and Group 2 medical locations, including: 

• BS 7671:2018 Amendment 4:2026, Section 710 

• HTM 06-01:2017 

• IET Guidance Note 7, Section 9 

Designed for different medical environments 

Designed and manufactured in the UK by Bender, EBBs are available for a range of medical applications, including diagnostic imaging and MRI, wards, recovery areas, operating theatres and individual treatment rooms. 

The key benefits of equipotential bonding:

EBBs Support:

Consultants and electrical engineers: 

Supporting specification and electrical design across Group 1 & Group 2 medical locations

Electrical contractors:
