Electrical connectors and associated methods for coupling to a first busbar extending in a first direction to a second busbar extending in a second direction are disclosed. A connector has a first mounting portion including a receiving portion configured to receive an end portion of the first busbar. A clamping portion is coupled to the receiving portion and configured to extend over the first busbar. The clamping portion is configured to impart a clamping force in a third direction toward the second busbar when the second busbar is disposed between the clamping portion and the first busbar. The connector also includes a second mounting portion coupled to the clamping portion, the second mounting portion arranged to be coupled to the first busbar to fixedly hold the second busbar between the clamping portion and the first busbar and to electrically couple the second busbar to the first busbar.
