Almost everything nowadays operates on electricity. The modern conveniences that drive our world depend on electricity. Without a constant supply, our world grinds to a halt, as massive blackouts have proven in the past. Electricity has two forms in modern electronics: AC and DC.

AC (alternating current), is most frequently used in devices that require high amounts of power to operate.

DC (direct current), is more commonly found in devices requiring smaller amounts of power to operate.

DC was the original electricity that was created by Thomas Edison. This style of electricity sends a current in only a single direction, from a power source and to the power source again in a loop. Today, DC is used to power electronics that require batteries. Any device in your home that uses batteries uses DC current. Interesting to note, if your battery is plugged into the power supply to recharge, it transforms AC current into DC.

Direct current is also used in manufacturing situations where electricity is generated on site for personal use. Factories and mills that require vast amounts of energy often create their own DC current to power their machinery. Most commonly, DC is found in steel mills, aluminum production, and is used to power mass transportation in large urban centers in the form of electric streetcars.

AC power is easier to generate, which is why we use it as our standard electricity nowadays. The alternating current design allows energy to flow in both directions, making electricity easier to create and use in society. Regardless of where the current is moving, it is always moving in both directions at once. This results in current being present at every point in the power grid at every time as long as the connection to the generation unit is intact. The power that comes from the power plants, down the lines to our homes, is always AC in nature, thanks to the way our modern power grid is set up.

The power grid operates by creating AC current and sending it down the power lines. This current can be at whatever intensity the power company chooses.

Frequently, the electricity coming from these lines is far too powerful to be used in our homes. The transformers that we see on power poles transform the electricity from its high-powered state into something that our homes can use. Without the transformers, we wouldn’t be able to use the power that our society depends on.

Regardless of the style that we use in our devices and our homes, electricity plays an important role in society. Without both AC and DC electricity, we wouldn’t have those things that make modern life as comfortable as it is.

The electrical panel inside of your home or office is where the breakers (or sometimes called switches) are located.  This is the “heart” of your electrical system.  Just like the heart inside of your body, if this major organ does not work properly, your blood circulation and limbs don’t stand a chance.  You could look at your electrical wiring as being your blood vessels and your appliances as being your limbs.  If your electrical panel, “aka” heart, is healthy and strong, your electrical wiring will operate properly, allowing all of your appliances to last longer.  Beware of old electrical panels; these could become a hazardto your home or business.

A variety of ways exist to quickly and efficiently complete an electrical installation. One method involves using pre-made and pre-fabricated conduits, cables, panels, and devices. Pre-fab strategies cut down on repetitive labor costs and scrap material waste.

Furthermore, pre-fabricated components are assembled in quality-controlled factories by highly trained technicians. This ensures that every device and termination is in working order and properly connected. These technicians work faster and cost less per hour than a journeyman electrician, therefore saving the contractor time and money.

Another option to increase efficiency involves using pre-wired devices. They can be used for repetitive tasks like receptacles, switches, light fixtures, data ports, or fire alarms. They save time by eliminating the need to terminate each device individually. Instead, boxes are made to order and ready to install. The desired length of cable is attached and ready to run to the nearest junction point. Simply attach the box, route the cable, and connect to the supply wires. Most suppliers prepare a custom quote, further reducing time spent by the foreman planning and ordering parts individually.

Pre-wired panels are possibly the simplest way to save money, as they require no special tools. Wiring up a panel at the shop before heading to the job site allows you to function test it before installation. This ensures proper functionality. In addition, it keeps the interior of the panel away from weather and other possible sources of job-site damage. For larger or more complex panels, suppliers can be arranged and have the work performed by specialized technicians. Panels can even be ordered with pre-cut and pre-terminated lengths of cable or cord.

Most electricians have used pre-formed conduit, especially PVC which requires specialized tools to bend. However, entire runs of pipe can be custom ordered and pre-shaped. Especially useful in underground conduit networks or when complicated bends are required, these pre-made conduits drop in place and fit perfectly to the engineer’s prints. They also ensure that conduits are not damaged or kinked during the bending process and that no sharp edges or rough spots are left to damage wires or cables.

If the project demands it, entire buildings can be pre-made and pre-wired in a factory setting by trained technicians who specialize in quickly and efficiently preparing custom ordered buildings. Especially useful in industrial settings, these buildings come complete with all interior and exterior lights, switches, receptacles, and control wiring.

Often, motor control centers (MCCs) for large industrial installations are constructed this way. Therefore, on-site electricians are free to begin immediately running cables to motors and devices, with simple termination points inside a completed building. In addition to using fewer electrician hours, they also reduce required hours from other tradespeople such as welders or cladding installers.

Finally, pre-fab strategies are a great solution for reducing material waste, worker hours, and downtime while making deadlines a snap. Projects run smoother with fewer errors.
