Connection Box

For your intersection projects, opt for a type CB1 service box according to MTQ requirements and distinguished by its most elegant exterior construction.


The service box is typically used at each intersection and serves as the initial connection point to the local electrical network. Its enclosure, terminal blocks, connections and robust electrical protection ensure the safety of workers and the protection of equipment connected downstream.

This box corresponds to the type CB1 service box described by the Ministère du Transport du Québec (MTQ) in its collection of standards. In order to ensure its compliance, the construction of this box complies with all the electrical and mechanical standards in effect, including the one specifically covering service boxes, i.e., standard 8702 of the MTQ’s Volume VII “Electrical Materials”.
