Busbars Basics

  • 490

What is a bus bar?

Busbars are designed for a solid connection point from one power supply to multiple branch circuits. Or many branch circuits back to a single power supply. Because switch panels are used as a positive power distribution method, bus bars are typically used on the negative side of the circuit.

What do busbars do?

Busbars perform a very simple but important function in an electrical system. One is to distribute power from a large positive conductor to individual circuit protection devices feeding a number of smaller wires.

The second is to collect small negative conductors and step them up to large ones.

How do busbars work?

Busbars are conductors or conductors used to collect electric power from incoming feeders and then distribute that power to outgoing feeders. In general, the busbar acts as an electrical junction where all incoming and outgoing electrical currents meet. The bus bar system has an isolator and a circuit breaker system to prevent mishaps. In an emergency, the circuit breaker trips and disconnects the faulty section from the circuit.

Where bus bars are used?

It is suitable for cars, RVs, trucks, boats, solar energy, and other electrical equipment, etc.

Busbars Application

Why bus bars are used?

With ships and vehicles, the use of electrical appliances has increased. At the same voltage level, executive functions become increasingly important. With cramped space and more wires to connect and more current to carry, organizing and marking wire connections is even more important.

In all but the smallest boats and cars, it is impractical to connect all wires for each load directly to the battery terminal or to the battery switch terminal. Large vehicles may have multiple layers of progressively smaller busbars, while small vehicles may have only one small busbar.

Bus Bars Specification

The following table provides a description of the product’s characteristics.

Features Benefits
Pressed-on busbar Because the bus is pressed on to the stainless steel terminal studs, it doesn’t require a securing nut that can come loose. In addition, there is a direct compression connection between the copper busbar and wire terminals instead of to a retaining nut.
Insert molded stainless steel studs In a distribution bus, the terminal stud is a compressive element, not a conductive element. Its purpose is to press the ring terminal against the busbar. Stainless steel studs molded into the base allow for high torque and therefore a tighter connection and lower resistance.
Press-on insulating cover The insulating cover provides insulation for all wire terminals connected to the busbar. This is especially important when the busbar is on the positive side of the circuit. Also, the cover design allows for terminals to be attached to the busbar from any direction.
Raised bus Raising the busbar above the surface of the base provides unobstructed wiring access, and allows for terminals to be inverted so that multiple terminals can be attached to each stud and screw.
Heat resistant base material Base material made of reinforced polycarbonate resists high heat—it will not burn in the absence of a flame.
