Abstract
A power distribution unit includes a fuse, a relay, a busbar, and a heat dissipation bolt. The fuse and the relay each have one terminal. The busbar is located between the fuse and the relay and connects to the two terminals. The heat dissipation bolt connects the busbar to a housing of the power distribution unit and includes two threaded bolts, one going through the busbar and the other going through the housing.
