Abstract: An electrical connector for transferring electrical signals between a tractor vehicle and a trailer vehicle is provided, the electrical connector including a connector plug and a connector socket in compliance with an industry standard. The connector socket includes a plurality of male contact terminals, and the connector plug includes a corresponding plurality of female contact terminals. The connector plug and the connector socket include a secondary electrical connection to support bidirectional data communication between a tractor vehicle and a trailer vehicle with greater bandwidth. The secondary electrical connection can include an additional electrical contact within a male part for engaging an additional electrical pin within a female part, wherein the male part and the female part are joined to, but laterally offset from, the connector plug and the connector socket.

Abstract: A surge protection system provides surge protection to a load. The load is connected to a breaker panel through the surge protection system and a surge protection module bridges the hot/neutral/ground such that the surge protection module absorbs surges from the breaker panel and beyond. Being that, after exposure to certain amounts of surges, the surge protection modules lose effectiveness for surge protection, the surge protection module is removable and replaceable by a user without risk of personal injury from shock caused by making personal contact with electrical power. During removal and replacement, the load remains in electrical connection to the breaker panel.

Abstract: A surge protection system provides surge protection to one or more circuits. Each circuit is connected to power and a surge protection module bridges the circuit such that the surge protection module absorbs surges from the power and/or the circuit. Being that, after exposure to certain amounts of surges, the surge protection modules lose effectiveness for surge protection, each surge protection module is independently removable and replaceable by a user without risk of personal injury from shock caused by making personal contact with the power and/or circuit. In some embodiments, a filter circuit is provided to filter out noise on the circuit. It is anticipated that the protection module includes indicators to inform a user that the protection circuit is operational and whether protection has been lost. Further, in some embodiments, a fuse is provided to protect the circuit from over current.
