K. is one of the newest members of the community and has been sending us articles for few weeks now. Today he chose to focus on domestic electrical wiring.

You can send us your writings too via email.

Introduction

Electrical power is transferred from generating stations to consumers at different voltage levels. Electrical power can be considered just like gas or water and same rule applies to its distribution i.e. proper pipeline and associated valves/switches.

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.

arc-fault-circuit-interrupter-afciNew article from A.N, a very experienced member in industrial, commercial buildings and residential power installations, testing, control and maintenance.

Enjoy and do not hesitate to ask him questions!

An arc fault circuit interrupter (AFCI) is a special circuit breaker, outlet or receptacle with the ability to detect, recognize and respond to dangerous electrical arcs in a circuit.

The device provides a higher level of protection compared to the standard circuit breaker. Its main advantage is the ability to detect and remove the hazardous arcing before it can cause a fire.
