What is the meaning of GI wire?
Further, earth wire is often laid in open where GI is safe from rust and other weather conditions. GI means Galvanized Iron wire. This is generally used in earthing of electrical machines, panels and transformers. Originally Answered: What is gi wire?
What does the G wire control on a furnace?
G: This wire controls the blower fan, which is responsible for pushing the warm or cool air through all the vents in your house. It is not a ground wire! C: This stands for the “common” wire in an HVAC system, and it provides power to the thermostat.
What is galvanized iron GI wire?
The GI wire or Galvanized Iron Wire is a result of a process called Galvanization. An anti-rust shielded zinc metal coating makes the wire rust-resistant. What Is GI Wire Mesh? Galvanized Iron GI is the material used for making GI wire mesh. The size of the mesh remains uniform and structured in a precise manner.
What gauge wire is used inside the wall?
Inside the walls, solid wire is usually used for 15 and 20A circuits (14 and 12 gauge) because there is no flexing of the wiring once it is in place. It is cheaper to make and easier to keep under a screw connection, and corrosion can only happen on the outside of the wire.
What is the G wire in thermostats for?
G: The G terminal controls the fan relay and is responsible for turning the blower fan on and off automatically or manually via the thermostat.
Is G wire needed for thermostat?
As you mentioned, you don't usually need a G wire for heating mode, but you do for cooling. In special circumstances a relay could be wired up inside of the air handler to make the fan come on with a call for cooling, but normally it's the thermostat that makes the connection that makes the fan come in in cooling mode.

What happens if you wire a thermostat wrong?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
How many wires do you need for a WIFI thermostat?
4 Wire Thermostat Wiring (Heat Pumps, HVAC) Smart thermostats like Nest and Ecobee thermostats require 4 wire thermostat wiring to function properly. In addition to heating (2 wire thermostats) and C or fan (3 wire thermostats), 4 wire thermostats include the cooling wire, usually in blue or yellow color.
What color is hot wire in a 120 volt circuit?
Black, Red, and Blue are used for hot wires while White is used as the neutral wire. Brown, Orange and Yellow are used as hot wires, while gray is used as the neutral wire.
What is C wire?
What is a C-Wire? A common wire (C-Wire) provides Wi-Fi thermostats continuous power by connecting it to a heating and cooling system (e.g. furnace). C-Wires are required on most Honeywell Wi-Fi thermostats, with the exception of the Smart Round Thermostat (formerly known as the Lyric Round).
Can I use RC wire as C wire?
No the Rc is the red wire. You need 5 wires or more for this to run with all the functions. You can use one of the other wires but you have to drop control of the fan. It will only come on when furnace comes on.
How can G wire be used as common?

Once you've installed the backplate of your new thermostat onto the wall unwrap the wire if it's wrapped around your wire bundle.
What color is C wire?
Blue wiresBlue wires are also called “C” wires because they are the Common wire. C wires are necessary for any “smart” thermostat that needs to be connected to a power source 24/7, regardless of your heat pump type.
What is the difference between a type W and a type G power cable?
These are industrial strength power cables. The cables can be used on all kinds of job sites to give power to machinery. They can handle 2000 volts of electricity and have rubber insulation around them. But there is in fact one main big difference between the Type W and the Type G power cables.
What is a type W wire?
Type W cables have no additional ground wires. There is a same size green wire in 3 conductor cables and higher. The different colors of wires help to easily identify each wire. The Type W cables are made ideally for industrial to light to medium duty mining applications because of it heavy duty and durable rubber jacket. It also can be used for AC systems, mobile and portable electronic equipment. This rubber jacket on the cable can withstands severe environmental conditions, as well as exposure to oils, acid, alkalies, heat, moisture and most chemicals. This shows that this cable really can handle anything, allowing it to be perfect for messy and hazardous industrial settings.
What is GI wire?
The GI wire or Galvanized Iron Wire is a result of a process called Galvanization. An anti-rust shielded zinc metal coating makes the wire rust-resistant.
How does GI wire work?
The crater is thus produced at a profound level in the earth and filled with coal and salt mixture. This is how the GI wires usually work as earthing for the entire building. All across the floor mains, this PVC copper wire makes its way to all earthing sockets.
How does GI wire create earthing?
It creates the earthing as it maintains contact with groundwater. Now pass the GI wire through the pipe and from the vessel for it to enter the main panel. This is how a safe earthing created for the entire building renders the property safe from any shock.
What is galvanized steel used for?
This galvanized steel is also used for handrails, roofing and walling. These are areas where high tensile strength is a must. The benefits include. Ability to stand high rusting and corrosion despite harsh weather conditions. Even zinc coating. Ease when it comes to handling and manoeuvring of bundles.
Wire diameter calculations
The n gauge wire diameter d n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39:

Wire resistance calculations
The n gauge wire resistance R in ohms per kilofeet (Ω/kft) is equal to 0.3048×1000000000 times the wire's resistivity ρ in ohm-meters (Ω·m) divided by 25.42 times the cross sectional area An in square inches (in2):
When was the SWG wire gauge made?
It was constructed by improving the Birmingham Wire Gauge. It was made a legal standard on March 1, 1884 by the British Board of Trade. SWG is not to be confused with American Wire Gauge, which has a similar but not interchangeable numbering scheme. A table of the gauge numbers and wire diameters is shown below.
What is standard wire gauge?
British Standard Wire Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn). It is also known as the Imperial Wire Gauge or British Standard Gauge.
What is the SWG gauge used for?
Use of SWG sizes has fallen greatly in popularity, but they are still used as a measure of thickness in guitar strings and some electrical wire. Cross sectional area in square millimetres is now the more usual size measurement for wires used in electrical installation cables.
What gauge wire is used for wire wrapping?
The most commonly used sizes for wire wrapping are 20 to 24 gauge. Wire Temper: Measures the amount of spring in the wire. Soft – Has no spring when you bend it and is good for making wire beads. Half-Hard – Has some spring, but is still malleable. It is good for basic wire work because it holds its shape well.
What gauge wire is used for chainmaille?
18 Gauge – heavy – often good for chainmaille or when a heavier look is needed. 16 Gauge – heavy – often used as a base to wrap finer wires around. 14 Gauge – heavy – often used as a base to wrap finer wire around. 12 Gauge – very heavy – hard to work with – good for rings and buckles.
