Godown Wiring Diagram – Tunnel Wiring Circuit and Working
Godown Wiring Circuit Diagram and its Working
Godown wiring circuit isneeded in tunnel like structures, warehouses, long passages, big godowns having lots of rooms and different portions.
It was the best choice to save electricity and energy consumption where only one load i.e. light bulb can be operate at a time. Nowadays, as CFL and LED bulb which consumes low energy, this type of wiring is avoided due to its complexity ignoring the power consumption.
In this wiring installation tutorial, we will be going to control three lights bulbs using one SPST (Single pole single throw or single way) and two SPDT (Single pole double throw or two way) switches.
Keep in mind that you may use many switches and lamps according to your needs while following the above tunnel and godown wiring schematic diagram. As the rating of each switch and lamps are same while only one load can be operational at once, therefore, use appropriate wire size and proper size MCB and suitable size and rating of switches according to the load rating.
Difference between Surge Arrester, Surge Suppressor, Lightning Arrester and Lightning Rod
Different terms used for arresters are sometimes confusing even professional engineers and electricians use them interchangeably.
We will discuss the main difference between the different types of arresters such as surge arrester, lightning arrester, surge suppressor and lighting rod as sometimes, they may used for same purpose. The difference shows that what kind of system you want to protect from what and how?

Let’s see the basic definitions of the following arresters. We will discuss all of them in details below.
Surge Arrester: is a device used to protect the electrical installations and equipment from electrical surges and transient voltage caused by electrical faults, switching, short circuits, sparks and lightning etc. Surge arresters are installed inside the panels to cancel out the surges.
Lightning Arrester: is a device used to protect the electric circuit and connected devices from the lightning strikes having high voltage transient surges. Lightning arresters are installed outside to ground the harmful effects of lightning spikes.
Surge Suppressor: Also known as transient suppressor or surge protector is a device installed in the home panel board to protect the connected circuits from electric surges and voltage spikes known as transients.
Lightning Rod: It is a device installed on the height location i.e. top of the building and transmission towers to provide a path to ground the lightning strokes. The lightning rod protects the structure from lighting surges.
Good to know: A surge arrester can be used as a lightning arrester but lightning arrester can’t be used as a surge arrester.

What is a Surge Arrester?
Surge arrester is a voltage limiting device installed inside the installation equipment panel to protect the insulation, equipment and machines not only from lightning, but also from transient voltage produced by switching, sparks, load shading and other electrical faults such as ground faults etc.
Surge arresters are used to limit the current and voltage surges to protect the low and high voltage appliances as well as communication lines. The most common surge arrester is a non-linear metal oxide resistors type in a porcelain or silicone rubber housing, and are fitted in parallel with the intended circuit to protect from surges and connected to the earth grid.
In olden days, the term “lightning arrester” was used in power system which is replaced by the new term as “surge arrester”. This is because the main reason for most of over voltages was lightning when the power system design was not that much complicated. In most advanced designs, load shading, sudden change in high power in load, and disconnector switching in EHV substation causes over voltage where surge arrester are used in a substation instead of lightning arrester which provides protection against all of the above mentioned surges. In LV/MV transmission and distribution lines, a new term as “line arrester” is also used for lightning / surge arresters.
What is a Lightning Arrester?
Lightning Arrester is a protective device used to protect the circuit from lightning strokes having high transient voltage surges, surge currents due to lightning, spark and isolation arcs etc.
It is used to protect the power system by redirecting the high voltage surges to the ground. Although, the earthing or ground wire also protects the overhead lines and power system from direct lightning strikes but it may fail to protect against traveling waves which may reach to the terminal connected devices and equipment. For this reason, surge diverters or lightning arresters are used to protect the power system against such produced surges by faults or lightning stokes.
Lightning arresters are installed on the peak height of a structure i.e. transmission poles and towers and building to provide a safe path to the discharging current and voltage caused by the lighting strokes to the ground to protect the system form lightning induced problems.
