Answer for USA, Canada and countries running a 60 Hz supply service.
Generally yes.
When installed where exposed to physical damage you must use Schedule 80 PVC. Most PVC is Schedule 40.
It should not be installed inside fire-rated walls.
It cannot be installed in theaters or similar assembly areas, exposed or concealed, except as provided specifically by code sections 518.4 or 520.5.
<><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What is difference between cleat and conduit wiring?
Cleat wiring is exposed while in conduit wiring the wires are well protected inside tubes/pipes.
Bends are made in PVC conduit using a tool known as a?
Bends are made in PVC conduit using a tool known as a heat gun or a heat blanket. If you want to make make accurate and aesthetically pleasing bends without distorting the pipe, the PVC conduit must be heated thoroughly - inside and out. This is achieved using a "heater box," or a "heater blanket." Greenlee tools makes both, specifically for working with PVC conduit. Also available are plugs for plugging the ends of the PVC lengths to be bent, for keeping heat trapped inside the pipe and speeding up the heating process.
When is it required to bond a junction box?
If a junction box is part of an electrical conduit system then it is required to be bonded so as to make the whole electrical conduit system continuously conductive.
Can indoor Romex wiring be used outdoor as long as it is inside of PVC conduit?
No, according to the electrical code the cable has to have a underground rating. That said many home owners do install indoor rated cable in PVC black water pipe and bury it for outdoor installations.
What is the IEE regulations on space factors in conduits and ducts?
This topic is covered in the IEE's On-Site Guide, a supplement to BS 7671:2008 Regulations for Electrical Installations.'Grouping' describes to the mutual heating effect of adjacent conductors. The effect of grouping acts to reduce the number of cables actually allowed into an enclosure because, as the number of circuits increases, the current-carrying capacity of the cables reduces -requiring the use of cables with larger cross-sectional areas! And using cables with larger cross-sectional areas may then require us to use larger-diameter conduit.In practice, this might also mean distributing the cables between, say, two smaller conduits (or by using a small trunking system).Guidance in this is provided by an equation called a space factor, where:space factor = [(csa of all cables)/(internal csa of conduit)] x 100 %...where the maximum permissible space factor is 40%. In other words, the area of the cables must not exceed 40% of the internal cross-sectional area of a conduit. The 60% empty-space requirement is intended to enable the dissipation of the heat produced by the current-carrying conductors grouped inside the conduit.
What are the methods of bending plastic conduit?
The first step is to place a spring inside the conduit thereby preventing it from snapping
What reaming method is there available to remove concrete inside a 2 PVC conduit?
It may be easier to simply cut out the section of conduit and replace it.
What is difference between cleat and conduit wiring?
Cleat wiring is exposed while in conduit wiring the wires are well protected inside tubes/pipes.

How do you put a 2 inch piece of condiut inside a half inch piece of conduit without altering the size of the conduit in any way?
It is easy to put a 2-inch long piece of conduit that is less than half an inch in any cross-sectional measure into a half-inch conduit.
What is a collection of bees called?
A collection of bees inside a space is called a hive. If they collect outside, such as on a tree branch or the side of a building, they are called a swarm
Is inventing a branch of science?
it is a sub branch which means that it is a branch inside another and that is physics
Is a building a LAN?
No, a building is a building. You can put a LAN inside a building, however.
What is hydraulic means?
Hydraulic Mean Radius = Cross sectional area of conduit divided by the inside (wetted) perimeter.
How do you get inside the building in wimpy wonderland on poptropica?
You go inside the open window on the top of the building
To rewire a 2 bedroom property that was built in 1956 Can we use the old conduit or Do we need to replace it Currently earth is attached to the conduit itself Any special cables we can use?
If the existing conduit has not been intentionally or accidentally interrupted it is still an adequate ground. If you are in doubt about this or if a test proves that it is not grounded, new conductors including a new ground wire can be pulled inside the conduit. If the existing conduit is flexible conduit and it has "jake" type twist connectors, rewiring with a ground is advisable as those type of connectors do not maintain a good ground connection.
Is there any way to fix a customized curtain rod?
A good way to fix a broken customized rod would be with electrical conduit. It is easy to use and most customized rods have a basic inside rod that can be matched with electrical conduit.
