Blue Sea Systems PowerBar Dual BusBar, 200A, 48V DC, 3/8"-16 Studs, Tin-Plated Copper, With Insulators

Overview

The Blue Sea Systems 2019 is a dual-stud common busbar for creating a single high-current connection point in DC systems up to 48V. It uses two 3/8"-16 studs and carries up to 200A, so it suits battery cables, charger feeds, inverter connections, and other heavy DC conductors that need a clean shared point.

The current path is tin-plated copper, and the base is glass-reinforced thermoplastic with a UL 94-V0 flame rating. That makes it a practical choice for battery compartments, consoles, machinery spaces, and other onboard areas where vibration, moisture, and salt-heavy air can work on electrical hardware over time.

This busbar is a good match when the job calls for a simple two-stud connection rather than a larger distribution block. On refits and service work, it helps tidy up cable routing and gives larger ring terminals a dedicated place to land without stacking everything on a battery post.

Key features

• Two 3/8"-16 terminal studs sized for larger ring terminals and high-current cable runs
• 200A rating with a 48V DC maximum for battery, charging, and main DC distribution circuits
• Tin-plated copper bus for strong conductivity and better resistance to corrosion in marine electrical spaces
• Glass-reinforced thermoplastic base with UL 94-V0 flame rating
• 100 in-lb stud torque specification to help secure cable lugs correctly during installation
• Compact layout that consolidates power sources or loads into one common connection point

Compatibility and fit

This is a common busbar, so it can be used on either the positive or negative side of a DC circuit as long as the system stays within its 48V DC limit and the connected cable, overcurrent protection, and load are sized appropriately. It is best suited to installations that need two stud connections and enough room for heavy cable bends and lug clearance around each stud.

Installation and setup

Mount the unit on a solid surface close to the batteries, charger output, inverter feed, or other high-current equipment to keep cable runs short and well supported. Use cable lugs that match 3/8" studs, tighten the connections to the stated torque, and support the cable weight so the studs are not carrying strain from unsupported conductors.

For boats that see regular washdown or damp bilge-adjacent conditions, place the busbar where it stays protected from standing water and where routine inspection is still easy. That makes it easier to spot loose hardware, heat discoloration, or cable movement before it becomes a bigger wiring problem.

Use on board

This part fits small to mid-size electrical builds where a compact common tie point is enough and a larger multi-circuit busbar would take up unnecessary space. It is especially useful when cleaning up battery bank wiring, combining charger or DC source connections, or creating a dedicated heavy-cable junction in a tight compartment.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
