Reverse current is another security risk. In normal conditions, distribution from power source is passed by busbar system to the devices with interconnection with voltage regulators and control units. In case of malfunction there is possibility for reverse current to occur.

Let’s find out more about it thanks to this article that our member Mile kindly sent us.

When we have reverse current situation, something is wrong with DC generator. So, generator fails and cannot provide electrical power and starts consuming current instead of providing it. Obviously, when this situation happens, generator is becoming a load to electrical distribution.

Basically, there are two methods for protection, reverse current cut-out relay and reverse current circuit breaker.

 Low voltage circuit breakers basics

Back to basics with our fellow member Pablo who chose to tell us about the different types of low voltage circuit breakers… Enjoy!

Every day there is more variety of electrical products including circuit breakers, sockets, switches, and others. Regarding breakers, they vary according to the manufacturer, which has led me a couple of questions:

What are the differences between them? Are they interchangeable? Why choose a particular manufacturer? What are the types? I will start with low voltage circuit breakers.
