As Summer is coming soon many people think to install new Air conditioner for their homes. Basically for homes there are two types of air conditioner available in market as given below:

1. Window AC
2. Split AC

Window AC is installed in window’s only as the name itself perdicts Window AC. Split AC can be installed in any room at any location but Split AC consists of two units Indoor Unit and Outdoor Unit, so its wiring is difficult as compared to window AC. Here we would discuss the wiring of window ac and complete accessories required to install with window AC for its proper functioning.

Material list required to install window AC

• Miniature Circuit Breaker
• Double Pole Switch
• Flex Outlet

Minature Circuit Breaker (MCB)

MCB is a device that provide short circuit and overcurrent protection to the equipment. If there is any kind of short circuit takes place in wires or in ac circuit then MCB trips due to large current flowing and saves the AC from damage.

Also when AC takes large current due to overloading of motor and compressor then in that case also MCB trips and saves the equipment from any damage. So MCB is most important device to be used in window AC circuit.

Flex Outlet

Flex Outlet is basically a connector that connects phase, neutral and earth wire and also consists of fuse system in phase that prevents window AC from any kind of sparking,voltage fluctuations etc.

All devices has discussed and required for wiring connection of Window AC Now complete wiring of all devices along with Window AC has shown below:

I hope you will get complete knowledge of Window AC wiring and this article helps you, Thanks for reading this article

All electrolytic capacitors are polarized, and carry markings to identify polarity of terminations.

Most small aluminium electrolytic capacitors carry a stripe on negative terminal side. In case of axial lead aluminium electrolytic capacitor, the stripe also carries arrow marks to point to negative terminal.

In addition, when lead wire are used as output terminals, negative terminal lead is shorter. So it çan be identified independent of other markings.

Large aluminium electrolytic capacitor with terminal disc has often red mark at base of + terminal.

In case of tantalum axial capacitor, often a + mark is placed to identify positive terminal.

What is polarization in a capacitor?

Not all capacitors are polarized, ones that are will be clearly marked with + and – where the leads go into the case.

Polarized capacitors are a type of capacitor called an electrolytic capacitor in which a chemical reaction on the surface of the capacitor’s anode forms an oxide layer that serves as the capacitor’s dielectric separator. Reversing the polarity would cause the oxide layer to dissolve causing the capacitor to short circuit, hence the need to be polarized.

Electrolytic capacitors are typically cylindrical with both leads coming out of one end of the can. They can be quite large. Failed electrolytic capacitors can split or even explode.

Cable Selection

What does polarized capacitors mean?

A polarized capacitor has a dielectric material in it similar to the acid in a battery.

Capacitors consist of a sandwich of two conductors separated by an insulator. In a polarized capacitor the insulating material is a dielectric, meaning it becomes a dipole when the capacitor is charged.

Ordinary capacitors do not have a positive and negative side, but polarized capacitors do have a positive side and a negative side. When they are connected to a circuit you must take care to connect the positive side to positive and the negative side to negative. Failure to connect it properly could damage the capacitor. Under some circumstances it could overheat and be dangerous.

The large capacitance of electrolytic capacitors makes them particularly suitable for passing or bypassing low-frequency signals, and for storing large amounts of energy. They are widely used for decoupling or noise filtering in power supplies and DC link circuits for variable-frequency drives, for coupling signals between amplifier stages, and storing energy as in

Since There are different sizes and types of cables available in market, we have to do cable selection to be used at specific location according to the usage. Types of cables are as follows:-

• Copper Cable
• Alluminium Cable

Also Copper and Aluminium cables are available in different sizes like 1 sq.mm to 300 sq.mm and different sizes carry different currents and also different gland sizes. One can do cable selection to be used after checking the current taken by cable which can be selected easily from below tables

From above table one can easily learn about copper cable size from 1.5sq.mm to 35 sq.mm their gland size, current carrying capacity and breaker to be used for particular cable.

Godown Wiring

Also we are providing a table of copper cable size 50sq.mm to 300sq.mm having complete specifications of gland size, current carrying capacity and breaker size. Kindly have a look

So In this article you have learned about copper cables and easily perform cable selection for particular job from these tables.

Fire basically conducts electricity the same way salty water does: both contain some concentration of charged particles that are free to move.
Water contains some concentrations of ions and protons (H++ protons). When there is a voltage difference, the ions will move according to their charge.
The hot gas of the flame contains positively charged ions and electrons, which will move in the same way as the ions in the water. The reason there are ions is that the heat of the gas is such that some of the electrons can free themselves from the attraction of their atoms.

For sure! Fire is a plasma, and plasmas have freely-moving charged particles within them. Anything that has freely-moving charged particles conducts electricity.

So metals, which have a sea of mobile negatively-charged electrons on their surface, conduct electricity. And saltwater…

Today In this world we are using large quantity of products in our day to day life, So there is huge demand of different products in bulk but one can’t manufacture products simultaneously. Now to satisfy the demand we have to keep the products ready in large godown or store rooms. Every one has watched once in a life below shown godown in their life.

These pictures shows ware house which we use to store large quantity of different types of products, Now here is the question How can one provide light arrangement for such large ware houses because these godowns are so large that if we can use simple lighting techniques which we use in complexes then large consumption of electricity would takes place which results in electricity wastage.

Since while working in godown if we switch on whole lighting system then all lights will glow which is wastage of energy as we only need the light in particular section where we have to work and not in whole warehouse, so this lighting technique is not energy efficient.

Solution

To tackle this situation we have to use godown wiring technique, by using this technique one can only lighten the particular section of godown where we have to work and the remaining section remains in dark which results to energy saving.

Godown Wiring

Godown wiring is a technique which we used in large ware houses for lighting purpose, In this technique we use two way switches as well as one way switch Now the question is what is one way switch and one is two way switch ?

So the answer to this question is one way switch has only two terminals while two way switch has three terminals one can easily differentiate between the by only watching their terminals you can also give a look to below pictures of one way and two way switches.

After watching these pictures you will learn about one way ans two way switches now the question rises how to use this now before these switches in godown wiring we have to learn about the combination of switches used so here is a simple thumb rule that if we have to use 10 number of bulbs in our godown then we have to use total 10 switches for 10 bulbs. out of 10 switches we have to use 9 two way switches and 1 one way switches. Similarly let’s take another example if we have to use 20 bulbs in godown then we have to use 19 two way switches and 1 one way switch, this is the way to use the combination.

Now another question is circuit diagram to be used to connect all these switches and bulbs in godown wiring so here is the answer below

The above circuit shows the godown wiring of total four bulbs which we are doing with the help of 3 two way switches and 1 one way switch as discussed in above paragraphs, Now one have to follow same circuit for any number of bulbs to be connected and easily do the godown lighting connections.
