Description

Technical Field

[0001] This utility model relates to a circuit breaker cabinet with dual output mode, belonging to the field of electrical equipment. Background Technology

[0002] With the increasing demand for electricity, diesel generator sets are gaining a larger share of the rental market and are widely used in construction sites, mines, roadside assistance, agriculture, and temporary events. Conventional diesel generator set designs typically use either the circuit breaker's built-in mounting holes or an extended copper busbar for wiring. This output method requires the end customer to crimp the copper connectors onto the main cable, necessitating the use of appropriate tools. This is inconvenient for simple and quick wiring in the rental market. Furthermore, the single copper busbar option limits the diverse applications for customers. Utility Model Content
