Ground electrical wiring

By

Grounding or earthing a wire is a process that prevents hazardous voltages from damaging your equipment and or appliances. A grounding conductor does not carry any current. This neutral wire is connected to the ground or earthed at the mane distribution panel in your home, which has the main disconnecting switch or circuit breaker. Homes that were built before the 1950s may not have a ground wire. However, homes built after the 1950s should have one. If you are unsure of this, then you should have an electrician inspect your home.

If your outlets have three prongs then there is a strong possibility that your system has been grounded. However, wiring mistakes can leave the grounding ineffective. A qualified electrician can examine your electrical system with a special testing device and tell you if your system is grounded or not.

Grounding your electrical system protects your family and your electrical appliances. Remember that electricity travels the least resistant path. Take your toaster for instance; if there is a fault in its wiring or your power outlet, electricity can flow on the metal on the outside of the toaster. This poses a very big danger as touching the toaster at this point can cause damage or death. The grounded wire prevents electricity from traveling through the metal body of the toaster.

Surge protection also requires a grounded system. Sudden increases in power can damage or even completely destroy electrical appliances. It is important to keep in mind that surge protectors only work if your electrical system has been properly grounded.

It's time to tackle some wiring projects in your home, but where do you begin? It's important that you know what you're dealing with before you start, so a little lesson in 'Wiring 101' is in order. From understanding the different types of wires you'll find to installing switches, outlets, and a few major appliances, let's look at the basics of home wiring.     01 of 09     The Common Wires in Your Home     Before you begin your first DIY electrical project, you should learn a little about the wires you'll be working with. Wires vary greatly and each is designed for a purpose.     The wiring in your home is chosen to accommodate the load it must carry as well as the conditions it will be exposed to. Some are designed for indoor use while others can be buried. Some are for your panel while others hook up your lights and outlets.     It may be confusing at first, but you will probably deal with only a few types of wire in your home.     02 of 09

How to install Gear switch

First we define the word switch gear? a switch gears are a combination of disconnect switches or circuit breakers used to control, protect and isolate electrical equipment. The switchgear consists of a cubicle unit that is attached to a lower frame and they help in identifying faults found in an electricity network such as generating, distributing r transmitting and helps in turning off power. You can call it TP&N OR SWITCH GEAR Electric switchgears are the heart beat of any company facility’s electrical system. The switchgears works as the intermediary between the incoming electricity from the utility companies and all other electrical circuits within the facility. They are of many  voltage classes; we have the low voltage (less than 1 KV), the medium voltage (1 KV to 75 KV), high voltage (75 KV to 230 KV) and the extremely high voltage (Above 230 KV). These switch gears can pose a serious risk to workers and if there are accidents, the likelihood of death is very high. It is th

Pool electric

It’s hard to imagine that a swimming pool has very intricate electrical requirement and they are by no means simple. Water and electricity make a deadly mix so watch out! This is not something for fun and games. This is why professional electrical contractors always follow strict protocols when doing the wiring for swimming pools. The electric requirements of a swimming pool comprise of a motor, pool lights, and filtering equipment. Electrical Pool Requirements All electrical wiring must be at least 5 feet away from the pool. The wires must also securely run through a non metallic raceway system or must be installed within a conduit. Electric pool equipment must also be installed in rooms or pits that have adequate drainage to prevent water accumulation. There must always be a failsafe method to disconnect all ungrounded conductors and the disconnection method must be accessible at least within 50 feet of the equipment. We all love to have underwater lighting in our swimming pools.
