Product Details
BB250-T3M10S8-C-BR-2 combines 3 x M10(3/8″) studs with 8 screw terminals on a 250 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.
BB250-T3M10S8-C-BR-2 / mixed terminal configuration.
- 01 Separate landing points on a common bus
3 M10(3/8″) studs and 8 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 Specified bus material
The brass bar is 3.5 mm thick. Stainless steel studs secure the lug connections. - 03 Covered connections for protected installations
A protective cover shields the terminal area. The cover is not a substitute for a sealed electrical enclosure where water or conductive contamination is present.

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 8 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.
