Abstract: Apparatus for enabling distribution of electric power, fusing, and/or ground connection in electrical systems is provided. The apparatus may include an extensible, interlocking, modular block of multiple-use modules. Each module may be configured to include a fuse or a link bar mounted within it. Each module may accept multiple sizes and types of fuses. Each module may be configured to include an external link bar for providing an electrical connection to at least one other module. Apparatus may enable distribution of electrical power, fused power, and/or ground connection from a power source to a plurality of electrical components while organizing and minimizing wired connections.
