The Solar System[a] is the gravitationally-bound system comprising the Sun and the objects that orbit it, either directly or indirectly.[b] Of those objects that orbit the Sun directly, the largest eight are the planets,[c] with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.[d]

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

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

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.
