The installation discipline and tests that make a busbar trunking system safe and reliable for decades.

Busbar trunking carries large currents, so the quality of its installation has direct safety and reliability consequences. Methodical installation, jointing and testing are what make the difference between a dependable system and a hidden risk.

Setting out and support

Runs are set out to suit the structure and future access, then supported at the manufacturer's specified intervals. Correct alignment and support prevent stress on joints and keep the system serviceable.

Jointing

Joints are assembled and torqued precisely to the specified values, because a loose joint creates resistance, heat and a potential failure point. Torque values are recorded as part of the quality record.

Testing before energising

Before the system is energised it is checked for insulation resistance and continuity, and inspected against the installation requirements. Commissioning records give the client assurance and a baseline for future maintenance.

Key takeaways

  • Set out and support runs to the manufacturer's spec
  • Torque joints precisely and record the values
  • Insulation- and continuity-test before energising
  • Hand over commissioning records as a baseline
