The electrical field is one that has seen a number of remarkable discoveries over the decades. One very important lesson has been the aspect of grounding of electrical currents. It’s true that we need electricity for almost everything in our daily lives and can’t even imagine a world without it. However, it continues to be one of the most dangerous elements on earth. If you haven’t already properly grounded your home’s electrical systems, you are taking a significant risk by not doing so.

Every electrical circuit has an active wire which supplies power; there is also a neutral wire which is responsible for carrying the power back. There is a third wire (grounding wire) that can be attached to the power outlets & the electrical appliances and devices; this wire is connected securely to the ground in your breaker box.

This third wire is the additional path that the electrical current can pass through to be safely returned to the ground, in case there is a short circuit; this prevents any harm being caused to anyone. In the event that a short circuit occurs, the current flows through into this grounding wire and it’s when you notice a tripped circuit breaker or a blown fuse in the electrical main board on your property. If this wire hadn’t been grounded, it would have resulted in a fatal shock.

This is one of the most important reasons to ground electrical currents. It’s the best way to protect your family members from electrical surges when they are operating any electrical appliances in the house. In case a lightning strike causes an electrical surge on your property it can result in extremely high electrical voltages in your system. When the wiring has the proper grounding, all the excess electricity gets diverted into the earth, rather than burning everything that’s connected to your electrical system.

When your installation is grounded, it becomes very easy for the power to get directed exactly to where you need it; this allows the electrical currents to efficiently & safely travel across your home’s electrical system.

A properly grounded system makes it much easier for the power to be distributed in the right amount to the right places. This plays a significant role in ensuring that there is no overload in the circuits. The earth becomes the common reference point for all the different sources of voltage in an electrical system.

One of the primary reasons why grounding is extremely effective in keeping you safe is because the earth is an excellent conductor, and electricity always takes the path that has the least resistance. When you ground your electrical system, you are giving it a path that it can easily take, rather than into you; this can potentially save your life.

If your home’s electrical system isn’t properly grounded, you are just risking the appliances and equipment that are connected to your system, being burnt beyond repair. If the situation gets out of control that can also result in a fire risking your property and causing physical injury, sometimes even death.

As a homeowner, you’re going to occasionally need professional repairs made at your house. For many jobs a cousin, a friend’s brother, or a great handyman recommended by a neighbor may be able to do a great job for a low price and it would be foolish not to accept those people to make light repairs or upgrades. However, when it comes to electrical work such a solution just doesn’t fly. First, it’s not legal for anyone who is not licensed to conduct electric work to your house. Second, there are safety issues involved if electric work isn’t conducted properly and third, if those safety issues come into play your insurance coverage is going to be void when their inspector determines unlicensed repairs have been made.

Automation lies at the core of much of our modern lives. However, it evolves at radical speeds. The simple concept, to build a machine to perform a task without human intervention, was the engine of the industrial revolution. Now that concept is the driving force behind robotics, self-driving vehicles, and a wide range of advanced technologies.

Most automated tasks are part of a closed-loop system. This system is designed so that the outputs are monitored and fed back to the controller. The controller changes its operation as needed. An example of a closed-loop system is a home thermostat, which monitors the air temperature. When the low set-point is reached, a contact closes in the thermostat, beginning a furnace lighting cycle. As the furnace runs, the room air temperature increases until the high set-point is reached. The contact opens and ends the furnace burn cycle. This is automation.

With electrical relays, it is possible to achieve a variety of automatic functions. A motor starter uses a relay to close a contact that sends electrical power to a motor. In addition, it closes a set of auxiliary contacts that keep the main relay closed. A control mechanism, such as a temperature input or a stop button, can be wired in series with the auxiliary contact. This allows for control of the motor. An expansion of relay logic is the programmable logic controller or PLC. Instead of mechanical relays, a PLC uses a set of input and output contacts connected to a computer controller. Software in the controller then dictates how the inputs and outputs interact. They additionally execute specific patterns of operations, based on programmed ladder logic.
