Circuit breakers are increasingly being used instead of fuses for transportation equipment of all types. Circuit breakers have many virtues: They're more durable, they're easier to reset and replace, and they can be ordered in types and sizes that work in most places where fuses would be used on vehicles.

Perhaps most important, circuit breakers with reset buttons enable users to immediately cut power, providing an added level of personal safety not available with fuses.

While circuit breakers are becoming more prominent in 12-volt system design, the fuse remains a common, and useful, technology. If you're not up on your fuses, here's an overview of where they fit into automotive circuit protection.

Controlling parasitic loads (battery drain) and properly distributing electrical power is crucial to keeping vehicles working. However, this requires balancing the needs of the battery against those of the electrical system.

Dual voltage electrical systems solve many power requirement problems in today's trucks, buses and motor coaches, but like any specialized technology, dual voltage establishes its own rules.

Power distribution modules, or PDMs, have been called by many different names: Power distribution centers or units, electrical centers, and even electrical boxes. In any case, it boils down to this: PDMs are circuits in an enclosure, distributing power from a central power source to many smaller circuits around a vehicle or equipment.

Relays, solenoids, and contactors are all switches—whether electro-mechanical or solid state—but there are critical differences that make each suitable for different applications. In this article, we will explain how each of these devices work and discuss some key selection considerations.

The battery cable is among the most important components in a battery management system. High quality battery cables will help ensure you have power and avoid battery drain—but only if they are properly sized, installed and maintained.

There are two things you must absolutely double-check when selecting your battery cables.

Now more than ever, it’s important to keep weapons safe from theft. The Advanced Gun Lock Timer with Lock-Out Protection, a new product from Egis Mobile Electric, raises the bar substantially on gun storage safety in vehicles.

Next-generation power distribution models, called hard-wired boxes, streamline circuit protection and power distribution with features that support easier installation and maintenance as well as protect against premature failure.
