Product Details
BB250X2-T4M10S3-C brings a dual bus bar layout into one assembly, with 4 x M10(3/8″) studs and 6 screw terminals in total. This 250 A model helps suppliers offer a coordinated connection assembly for protected vehicle electrical compartments.
BB250X2-T4M10S3-C / mixed terminal configuration.
- 01 A coordinated dual assembly
The dual arrangement groups the connection hardware in one assembly. The complete product has 4 x M10(3/8″) studs and 6 screw terminals. - 02 Distinct terminal layout
The terminal count describes the complete assembly, so a buyer can compare it directly with the physical connection requirement. Do not multiply the count by the X2 designation. - 03 Covered connection area
The cover provides a physical barrier over the terminal area. Locate the assembly inside a protected compartment and retain access for cable inspection and service.

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.

Counts are totals for each listed assembly. Dual assemblies are not rated by adding two current values. Black/red options do not mean that a pair is supplied.
Common DC Connections in Practice
Typical uses for protected vehicle and onboard electrical installations.
RV electrical compartments
Use the coordinated dual layout when planning a protected onboard connection assembly. Keep the separate connection paths clearly identified and route cables so that each terminal remains accessible.
Commercial vehicle auxiliary wiring
A dual assembly can bring the connection hardware together in a serviceable compartment. Evaluate the physical cable arrangement as well as the stated current rating; dual construction does not imply double the current capacity.
Application examples describe potential installation contexts, not verified fitment to a particular vehicle. Keep live connections protected from water, conductive debris and accidental contact.
