What is a Busbar Power Distribution System?
A busbar power distribution system is a set of pre-engineered solid copper conductors that be interlocked together to create various system configurations and lengths, providing a standardized solution for connecting and mounting electrical components inside the panel.
A typical busbar system consists of the following components:
Copper busbar that can be flat or shaped;
•Busbar supports providing excellent mechanical and electrical bracing of the system;
•Simple touch-safe cover system for contact hazard protection;
•Connection components bringing power to and from the busbar (adaptors, clamps or bolt-on)
