Southwell School, New Swimming Pool

The installation of the new swimming pool at Southwell School involved comprehensive electrical work to support the facility’s operation, safety, and functionality. This included the removal and re-routing of existing electrical infrastructure, as well as the installation of new systems tailored to the pool environment.

Electrical Scope:

• Cable Isolation & Disconnection:
  • Isolation, disconnection, and removal of submain cables supplying the existing laundry building to make way for the new pool systems.
  • Diversion of existing Ringmain 2 cables between the main switchboard and the management building to facilitate the pool’s power needs.
• New Electrical Connections:
  • Installation of a Jean Muller NH1 250A fuse-disconnect at pillar box PB-2, fitted with 125A gL-gG fuse links.
  • Running of a 35mm² 4c + NS submain cable from PB-2 to the new pool plant room for power supply.
• Distribution & Control:
  • Installation of a custom-made IP54 distribution board and control panel to manage power and control systems for the pool.
  • Electrical reticulation throughout the site, including ducts into the plant room for incoming submains and outgoing sub-circuit cabling.
• Lighting & Power Systems:
  • Interior and exterior lighting, including special in-ground sign lighting for visibility.
  • Installation of general-purpose socket outlets and wiring for fixed appliances and equipment.
  • Emergency, exit, and evacuation lighting systems to meet safety regulations.
• Swimming Pool Equipment:
  • Electrical systems for pool heat-pump and filtration equipment, including wiring and control for the Variable Frequency Drive (VFD) for the filter pump. This section was managed on a design-build basis, ensuring it met the specific needs of the swimming pool's operations.
  • Power supplies and controls for retractable pool covers, improving operational efficiency and safety.
• Earthing & Bonding:
  • Main earthing and earth conductors installation.
  • Equipotential bonding, including special bonding for swimming pool environments to meet stringent safety regulations.
