As reported by Power Assemblies in their article “What Are Electrical Busbars?,” electrical busbars are foundational connectors found in nearly all power distribution solutions. Busbars enable equipment to conduct large amounts of electricity, making them a preferred choice for low to high voltage projects. Power distribution units that feature high-quality, low-cost, and easy-to-install busbars allow for seamless connections with camlock generator cables, reducing the time spent on setup and increasing productivity.

The Role of Busbars in Electrical Systems
Busbars are bars or strips of solid, conductive metal used to transport electric current from one location to another with minimal energy loss. Compared to cables, busbars provide significantly more surface area for conducting electricity. While cables consist of many thin, insulated strands bundled together and wrapped in a protective jacket, busbars have a wide and flat design ideal for carrying large amounts of electricity. Typically uninsulated, busbars efficiently dissipate heat while conducting electricity.

Busbars are rigid and are used in equipment for heavy-duty applications that generate substantial vibrations. If busbars begin to shake or deform while conducting electricity, it can cause arcing off the intended path. To ensure safety and reliability, busbars are securely bolted inside equipment so that all components remain in place and operate safely. Each power distribution unit is rigorously tested before being dispatched to ensure it arrives ready for installation at the customer’s job site.

Types of Electric Busbars
Electrical busbars, made from solid, conductive metal, can be fabricated from various materials depending on the required current capacity and budget constraints. Copper is the most common material due to its durability and excellent conductivity. Often, solid copper busbars are coated in tin or silver, which protects the copper from oxidation, corrosion, and galling while enhancing lubricity and supporting conductivity for optimal performance.

Busbars come in three main shapes: thick bars, flat strips, and rods. The choice of shape depends on the amount of electricity required, the space available in the enclosure, and the overall design of the electrical system. Thick bars offer the most surface area and are ideal for high-voltage applications. Rods and flat strips are used where space is a concern, with flat strips offering flexibility due to their thin, wide design, and rods being cylindrical.
