Product Details
BB1-1A provides a single M10(3/8″)/M8(5/16″)/M6(1/4″) connection post with black and red base versions. Its 80 A current rating and stud interface provide a straightforward reference for vehicle wiring suppliers selecting a mounted cable termination point.
BB1-1A / mixed terminal configuration.
- 01 A defined cable termination point
The 1 x M10(3/8″)/M8(5/16″)/M6(1/4″) stud gives a cable lug a dedicated mounting point. This is a connection component, not a battery disconnect switch or a fuse holder. - 02 Match the lug to the stud
The M10(3/8″)/M8(5/16″)/M6(1/4″) interface identifies the required lug-hole fit. Plan the cable approach and access for securing the connection; stud size alone does not define the permitted cable cross-section. - 03 Visible base identification
The black and red base versions provide a visible reference within the wiring assembly. Use consistent labels and polarity conventions throughout the installation.

Common DC Connections in Practice
Typical uses for protected vehicle and onboard electrical installations.
Vehicle wiring service points
Use the M10(3/8″)/M8(5/16″)/M6(1/4″) post as a mounted cable termination point in a guarded electrical area. Match the mounting location to cable access and service requirements.
Aftermarket wiring assemblies
A connection component for wholesalers supplying vehicle electrical repair and accessory-wiring parts. Specify the connection arrangement required by the installation; the product does not switch or fuse the circuit.
Application examples describe potential installation contexts, not verified fitment to a particular vehicle. Keep live connections protected from water, conductive debris and accidental contact.
