💡 Why install a dedicated copper bus bar array instead of running individual jumper wires everywhere?
Setting up a central distribution hub keeps your wiring harness neat and handy while preventing unwanted resistance across long runs.
- Thick copper conductors dissipate heat fast and carry heavy startup surges without degrading over time
- Multiple tapped connection points let you attach radios, navigation gear, and relay clusters in cramped compartments
- Screw top covers lock live connectors in place so salt spray and engine vibration never cause sudden power loss or tripped breakers
