Product Details
BB300-T3M10S10-C-BR combines 3 x M10(3/8″) studs with 10 screw terminals on a 300 A bus bar. The mixed connection layout gives cable lugs and smaller terminated conductors their own landing positions, helping installers organize a common supply or return connection. Black and red versions share the same connection layout.
BB300-T3M10S10-C-BR / mixed terminal configuration.
- 01 Separate landing points on a common bus
3 M10(3/8″) studs and 10 screw terminals distribute connections along the bar rather than concentrating every lug on one post. These positions share a bus; they are not separately isolated circuits. - 02 A covered terminal area
The polycarbonate dust cover helps shield the connection area from incidental contact. Provide sufficient installation clearance for access to the terminals with the power isolated. - 03 Black and red versions
Black and red versions let wholesalers offer consistent color identification across common supply and return layouts. The electrical connection configuration remains the same for both colors.

Terminal counts refer to one product assembly. Color versions are not added together. Mounting screws are not counted as electrical screw terminals.
Current rating applies to the product, not to each connection. Provide circuit protection separately. Inch sizes are approximate references, not interchangeable thread specifications.
Compare Connection Layouts and Ratings
Compare this model with other connection formats in the DAIERTEK range. Matching terminal counts do not establish mechanical interchangeability.

Common DC Connections in Practice
Typical uses for protected vehicle and onboard electrical installations.
Multi-accessory vehicle wiring
The 10 screw positions accommodate multiple terminated conductors on a common supply or return point. Individual accessory circuits still require appropriate protection elsewhere in the system.
RV control and distribution compartments
Use the M10(3/8″) stud connections and separate screw positions to organize common connections behind a control or distribution panel. Keep the assembly dry, guarded and accessible for service.
Application examples describe potential installation contexts, not verified fitment to a particular vehicle. Keep live connections protected from water, conductive debris and accidental contact.
