Commissioning

• After the entire busway system is installed, the insulation resistance should be greater than 0.5 MΩ.
However, this value will be reduced over time due to the humidity in the installation place. When the
busway is operating with connection to the power, the insulation resistance shall be not less than 0.5
MΩ. If the insulation resistance is within 0.1 MΩ~ 0.5 MΩ, the busway can operate at no load for 4~16
hours and then check insulation resistance again. If the insulation resistance is less than 0.1 Ω, the
busway shall not be energized.
• The busway system should be subject to electrical test before being energized. All connection
equipment of the system should be associated properly.
• Power transmission to busway
- The operator must be qualified professional electrical installer. Non-specialized persons should not be
allowed to stay on the site
- During power transmission, the busway should not be at any electrical load, and all the distribution
devices should be disconnected
Caution
The entire busway system should be made mega test before energizing.
WARNING
Do not attempt to inspect the busway when energized.
