DELIVERING A MODERN IN-THEATRE INSTALLATION
Inside the new trauma theatre, systems were installed that are specifically designed for a Group 2 clinical environment. A new Equipotential Bonding Busbar, which is a terminal bar used to connect all metallic parts in a specific area, such as a medical location, to a common grounding point – was installed to ensure all protective conductors (used to prevent electric shock and reduce fire risk) were securely bonded, providing a stable and safe environment for patients and staff alike.
An Isolated Power Supply (IPS) system was also installed. This type of system continuously monitors electrical insulation resistance, reducing the risk of electrical faults in an environment where patients may be connected to life-supporting equipment. IPS systems are a core requirement in modern theatres and form part of the wider strategy to protect against failure.
A new surgeon’s control panel was fitted to give clinical teams direct, reliable control over theatre services such as lighting, ventilation alarms and power systems. This panel was integrated with the hospital’s main systems, enabling seamless operation and helping staff manage their environment efficiently.
Dedicated supplies were installed for theatre ventilation, surgical lighting, and medical equipment. These services were carefully routed to meet the strict spatial requirements of operating theatres and tested as individual systems before being commissioned as part of the integrated infrastructure.
Close coordination was essential throughout the installation. C&B Electrical worked in partnership with the main contractor, Medical Air Technology, to ensure containment systems and cable routes were properly aligned with mechanical ductwork and plant connections.
Regular planning meetings and on-site reviews helped avoid clashes and reduce rework, supporting delivery within the agreed programme.
MANAGING DISRUPTION IN A LIVE ENVIRONMENT
The trauma theatre installation took place in a busy, fully operational hospital. Minimising disruption was essential. A phased programme was developed that allowed work to continue around the hospital’s day-to-day operations. Temporary power isolations were planned in close consultation with the estates team and contingency measures were always in place to protect patient care.
Strict infection control measures were upheld throughout. The project team maintained sterile barriers and ensured physical segregation of the work area. Dust suppression and cleaning protocols were enforced to protect adjacent clinical areas. Noisy works were scheduled outside peak times to avoid interference with patient care.
C&B Electrical’s team was fully trained in hospital procedures. Daily briefings were held with the estate and clinical teams to ensure alignment with hospital priorities and respond quickly to any operational challenges. The structured and responsive approach enabled the project to be completed without disrupting clinical services.
MEETING SAFETY AND COMPLIANCE STANDARDS
The project was delivered in full compliance with current healthcare electrical standards. The IPS system was tested under simulated fault conditions, confirming its ability to safely support applied medical equipment. UPS systems were also commissioned and tested to demonstrate seamless transfer in the event of mains failure.
All electrical systems underwent rigorous final testing in line with BS 7671, the IET Wiring Regulations. This included checks for polarity, (to determine the direction of current flow) earth fault loop impedance, prospective fault current and the functionality of protective devices . Full certification was provided to confirm compliance.
C&B Electrical delivered a comprehensive handover package including as-built drawings, test results, and manufacturer documentation. These resources form part of the hospital’s statutory maintenance records and will support future inspections, reporting, and asset management.
Health and safety were embedded in all site operations. Risk assessments were updated daily to reflect changing conditions. Toolbox talks were held regularly to keep the team alert to project-specific risks, including infection control protocols and working near live systems. The project was completed safely, with no reportable incidents.
