- In today’s video we want to talk to you about a common component commonly used by most almost all electricians today. Electrical conduit. More specifically, we want to discuss what electrical conduit is, and why it is so widely used in the electrical industry. We, will also look at some of the different types of electrical conduit that are MOST commonly used in industrial, commercial and residential applications.
Electrical conduit is simply a tube that is used for electrical wires to pass through to provide protections to both the wire, and to any persons who might be close to that wire run. It can be found in many different applications, and also many different variations depending on the specific applications it is being used in. Electrical code will often dictate when conduit must be used, as well as what type of conduit for the various different applications you might see it being used.
Let’s look at some of the most common types of electrical conduit, and where you might see each type being used.
First, let’s look at conduit that are made from metal, as these are probably the most used conduits we see today. Rigid Metal Conduit, or RMC is very thick walled type of conduit, commonly steel that has been galvanised, but can also be found in aluminum. This is considered one of the most durable and rugged types of electrical conduit that is used today, and is very common in industrial applications. In most cases, you will need to cut and thread this type of conduit, which can require some special equipment.
Another very common type of metal conduit is Electrical Metallic Tubing, or EMT. EMT is a much less expensive option in comparison to RMC. EMT is a much more thin walled conduit, not providing as much protection. It also much light and easier to work with than RMC, but does not provide the same amount of protection. In most cases EMT will not need to be threaded as it can be used with various different types of connection fittings, which can make it very versatile. EMT is also very common in industrial applications, but is better suited for commercial applications. EMT is generally made of coated steel, although it can be found in aluminum. There are other types of metal conduit such as: Galvanized Rigid Conduit (GRC), or Intermediate Metal Conduit (IMC), but they are not as common in most applications.
Now let’s look at some non-metal variations of electrical conduit. Must like with metal, there are many different types of non-metal conduit such as: PVC, Fiberglass Reinforced Conduit, Rigid Nonmetallic Tubing (RNT).
There are also several types of flexible non-metallic conduits that can be used an a variety of different applications. For the purpose of this video we will focus on the most common type of non-metallic conduit, which is PVC. PVC conduit is considered by most to be one of the lightest and most easy to use types of electrical conduit that we use. Also, PVC conduit is typically found at a lower cost than some of the other options. You can find in several different wall thicknesses depending on your applications. It is very common to see PVC conduit used underground and embedded within concrete because of its non-corrosive characteristics. There are many different sizes and fittings that can be used, which makes it very versatile for many different applications. It is not intended for areas that will be exposed to direct sunlight, as this can degrade the material over time. For the most part, PVC is a great option for the majority of underground scenarios, and is commonly used in industrial, commercial and residential environments
As you can see there are many different types of electrical conduit, and many different use cases that is can be found it. It is a tool that has allowed electricians to do there job more effectively, while providing a more safe environment for both the wires in the conduit, and the people around it.

If you're doubting your DIY abilities just remember, you conduit :)
Simply awful... congrats. 12/10 would def read your comment again.
Ahhhhh ha ha ha!!!!!!!!!! :)
thanks for making me laugh while it's 11 pm and I slept 5 hours last night. lol
Hey aren't you gay?
Thank you this video answered my question
please can you share with us how those conduit used in practice.
What are the advantages of frls conduit pipes?
EMT vs Heavy Walled Conduit same as light gauge vs heavy gauge?
Which would be the best material for pipes in outdoor installation (exposed to sun,rain etc) PVC or HDPE ?
Great videos
Hi , in which NEC clause its mentioned that conduit is mandatory and must use ? May you please answer ?
This was helpful. Danke schon
i can only find the little thumbs up, how do i install (unlock) the big thumbs up feature?
what tool used to bend heavy walled conduit?
Hydraulic bender
Flexible conduit reviews, please.
white vs gray pvc. Can you use gray and white interchangeably?
White is for plumbing. Gray is for electrical. Do not interchange.
Dear gentleman
Can i use UF wire with PVC conduit for underground aplicaciones from a house to a barn ..?
Yes.
Rather than replace a conduit, can you just thread new wire through the old conduit?
depends on what you are doing this for. if this is an installation where a piece of broken conduit caused the issue or you are for some reason the circuit needs rerouted at a longer distance I'd replace it with the wire. Conversely it possible for wire that just ove 25 years old under heavy use to need replaced and in that case yes you can theoretically just attach the new run to the old run and thus replace the old buy pulling it through. This does assume that you don't need upgrade your wire size and or the conduit was large enough to start with. Beyond that if you are shortening the wire run distance sure that is usually fine as you just replace any cut ends and keep the rest. Does that answer your question? At Least partially?
HELLO SIR ,PLEASE MAKE VIDEO ABOUT CONDUITS COMMMERSIAL HOUSE DIAGRAM..PLEASE
Thanks for the video =)
My pleasure!
I’m having concrete poured in my backyard 6 inch depth I want to run a better line from the back of the house to garage as it’s just a burial line now how far do I need to dig / bury the EMT piping under the concrete ?
You want to use a PVC conduit for that
Right. Do you know how far I need to dig the pvc pipe ?
What type of conduit used for exposed pipe?
Jan Wick , rigid , IMT and liquid tight flex
I wonder what they call this stuff in my country
this stuff is great
nice
Ah man! That is awesome! Getting a laugh today! Metal conduit! Scary! Yes! Agreeded PVC, non corrosive! I'd sooner use that and not have to think about possible issues with arching! I am aware of the dinkery with all this non sence! Video helped to solve that and have a second person confirm!
Why use a hard pipe and not a flexible one? What’s the difference
This is a man who wears gloves to work every day.
Are you sure about that?
I have a dream where I can build an industrial themed pc with big exposed fin stack heat sinks, and flexible metal conduit used as sleeving for the cables. Unfortunately I cannot find anyone who produces conduits of that size.
Brake lines from an auto parts store.
What is the outside diameter for electrical emt pipe? You could save a daughter father fishing trip :)
Hey Nathan! The typical diameter for EMT is 1.163''. Thanks for the support, enjoy your trip :)
What are the advantages and disadvantage of all conduits and where can they be applied?
Too long?
Oops...
Read the article numbers in NEC (national electrical code). Example Article 352 PVC Rigid Polyvinyl Chloride Conduit. For instance, if you read article 352.10 Uses Permitted you can get an idea of how PVC is used (or a scope of applications). An Electrical Illustrative Handbook helps too, but a TH-cam video like this one is worth a thousand words.

hehehehehe
Who typed Minecraft conduit and got this
me
a minute and a half for the intro and zero information
