Abstract: A power terminal block that accommodates busbars with various lengths and terminal positions is provided. The power terminal block includes a pair of insulators and a busbar. Each insulator includes a base, a shelf, and an insulating partition. The shelf is coupled to the base and is configured with a busbar mounting stud. The insulating partition is coupled to the base and the shelf. The busbar is configured to attach to the busbar mounting stud in each insulator. The insulators are spaced apart at a predetermined distance to receive a busbar of any length.
