Blue Sea Systems engineers marine electrical components that stand up to vibration, moisture and high current. This collection covers busbars, PowerPost connectors, CableClams and insulators for clean, safe DC wiring. Building a Reliable DC System with Blue Sea A clean power distribution layout starts with the right connection points. Busbars give you a common tie point for grounds or positive feeds, while PowerPost connectors join heavy battery cables to a single stud. CableClams seal wire entry points to keep water out of panels and junction boxes. Matching Studs and Amperage Size each part to your load. PowerPost connectors come in stud sizes from number 10 up to 3/8 inch, so match the stud to your cable lug. Check the amperage...

Blue Sea Systems engineers marine electrical components that stand up to vibration, moisture and high current. This collection covers busbars, PowerPost connectors, CableClams and insulators for clean, safe DC wiring.
A clean power distribution layout starts with the right connection points. Busbars give you a common tie point for grounds or positive feeds, while PowerPost connectors join heavy battery cables to a single stud. CableClams seal wire entry points to keep water out of panels and junction boxes.
Size each part to your load. PowerPost connectors come in stud sizes from number 10 up to 3/8 inch, so match the stud to your cable lug. Check the amperage rating on busbars against your total system draw. Insulated covers and proper stud sizing prevent shorts and keep terminals safe in a tight engine space.
A busbar is a single metal bar with multiple studs that acts as a common connection point. It lets you tie several ground or positive wires to one spot instead of stacking many lugs on a battery terminal.
Match the stud diameter to the hole in your cable lug. Blue Sea offers number 10, 1/4 inch, 5/16 inch and 3/8 inch studs. Choose the size that fits your existing lugs and amperage.
No. CableClams use a rubber grommet that compresses around the cable to form a watertight seal as you tighten the body, so no extra sealant is needed.
