Can Wiring be buried At Any Depth?

Can Wiring be buried At Any Depth?

Landscape lighting can work wonders for your home. Besides adding to the aesthetics of your home, these outdoor electrical fixtures also make your place safer by illuminating it at night. Proper outdoor electrical wiring is needed to make these landscape lightings, pump, lawn mower, or any other electrical devices work outside. Whenever you call an Atlanta electrical contractor to install outdoor wiring, he may place the wire overhead or bury it in a trench.

The overhead wiring not only spoils the view of your home but can also prove to be dangerous; thus, burying the wire is the most popular option. Before the contractors get on with the job of digging the trenches and burying the wires, they need to take into account the National Electrical Code (NEC) and all local codes set down for choosing the right wire and the correct depth at which they need to be buried.

Keeping the safety of your family members in mind, the following facts should be noted when the wiring has to be buried:

  • If the wire is placed in the metallic conduit, you need a depth of about 6 inches for burying the cable. The pipe in which the wire is placed is made using aluminum or steel. To prevent the corrosion of the aluminum conduit pipe, paint it by using a bituminous based solution.

The wire must run all through the metallic conduit before it comes out from the trench so that it doesn’t get damaged due to moisture, other natural elements, insects, and pests.

  • If a wire is placed in a rigid non-metallic conduit, the NEC suggests placing the wires at a depth of 12 inches. Wires should be placed in a rigid conduit that is made from high-density polyethylene or polyvinyl chloride.
  • If you are using an underground feeder cable that has to be buried directly in the ground as it comes with a weatherproof casing, you need to place it in an 18-inch deep trench since there is no conduit to protect the wire.

The above guidelines have been issued by the NEC, but Atlanta electrical contractors should also check the local procedures before they actually start the work.

Surge Protectors-How Do They Work?

Surge Protectors-How Do They Work?

You may have dressed up your home with the latest electronic gadgets, but the sudden voltage spikes can render them useless and could also lead to fire hazards. In Atlanta where lightning is a common sight during monsoons, a high power electrical surge could wipe the life out of all your electrical equipment if surge protectors are not installed in your home by Atlanta electrical contractors in Atlanta GA.

With the change in the weather conditions, say from warmer to cooler, Atlanta residents take out their electric blankets, room heaters, and other gadgets that put more load on the electrical circuit; this could cause electrical surges. If you want to increase the life of your electrical equipment by 30% and want to save your family from electrically related casualties, install a surge protector for your entire home.

A surge protector transfers the excessive current from the electrical outlet into the power strip, which is then directed to the grounding wire. If you are eager to learn how surge protectors work by diverting the voltage surges, then read on:

A surge protector contains a component known as MOV or metal oxide varistor that helps in diverting the extra voltage. MOV establishes a connection between the heated power line and grounding line.

MOV is made using three parts, namely two semiconductors and a small piece of a metal oxide material. This metal oxide piece is joined to the grounding and the power line using two semiconductors which has a variable resistance. When excessive current flows through the surge protector, the MOV conducts a large amount of current to reduce excess voltage.

Once the extra current flows from the MOV to the earth, the voltage is restored to the normal levels and the resistance of the MOV increases again. Therefore, the MOV diverts only the excessive surge current, while it continues to supply normal electric voltage to the electronic devices that are connected to it.

There are large varieties of surge protectors available in the market that can be installed by Atlanta electrical contractors depending on your requirements. Enjoy a peaceful sleep by installing surge protectors in your home that will help you save power and protect your equipment from electrical upsurge.
