How to use
To install the Legrand BI3-3P-12, first ensure that the main power supply to the distribution board is completely disconnected. Measure and cut the busbar to the required length if necessary, ensuring that the ends are properly insulated. Insert the comb teeth into the corresponding terminals of the circuit breakers, ensuring a firm and secure fit. Tighten the terminal screws on the circuit breakers to lock the busbar in place, verifying that all connections are solid before restoring power.
What to consider before purchase
Verify the compatibility of the busbar with your specific circuit breaker model
Ensure the current rating of the busbar meets your system requirements
Check the physical dimensions and terminal spacing of your existing equipment
Confirm that the installation environment complies with local electrical safety standards
Usage recommendations
Always use appropriate personal protective equipment and verify that the circuit is de-energized before performing any work inside an electrical panel. Ensure that the busbar is correctly seated in the terminals to prevent arcing or poor electrical contact.
