An electrical connector assembly may include a connector body having a conductor receiving end, a first link interface, a second link interface, a first connector end, and a visible open port between the first link interface and the second link interface. The first link interface may be conductively coupled to the conductor receiving end and the second link interface may be spaced axially from the first link interface and conductively coupled to the first connector end. The first link interface and the second link interface are configured to receive a link assembly therein. An insulative material may be positioned within the connector body axially between the first link interface and the second link interface. At least a portion of the insulative material may be visible through the visible open port.
