PVC is a material, Poly vinyl chloride - a type of plastic. 20 mm is a size, probably inner diameter of a cylindrical pipe. Conduit means that it's used to run something like other wires, or a thinner pipe, through.
PVC is cheaper but is used differently. PVC is usually baried in ground and emt usually runs exposed. You can use PVC exposed if it is schedule 80 gray PVC electrical conduit. Schedule 40 is for under ground
can you used pvc pipes in a commerical business kitchen
Yes.
The type of conduit strap you should use depends on the material and size of the conduit you're working with. For PVC conduit, use PVC straps; for metal conduit, opt for metal straps. Ensure the strap is compatible with the conduit size and securely fastens the conduit to walls or ceilings. Additionally, consider the environment where the installation will take place, as some straps offer better resistance to moisture or temperature variations.
Yes, if it is rigid PVC conduit approved for electrical installations. Don't use PVC water pipe as it will be rejected if inspected.
For underground conduit runs, PVC is by far the better of the two conduit systems.
The "How Many Wires in PVC Conduit" chart typically accommodates up to 9 wires in a PVC conduit.

The NEC PVC conduit fill table provides information on the maximum number of conductors that can be safely installed in a PVC conduit based on the size of the conduit and the size of the conductors.
The PVC conduit fill table provides information on the maximum number and size of cables that can be safely installed in a PVC conduit based on its diameter.
Schedule 80 PVC electrical conduit is a type of conduit that is thicker and stronger than Schedule 40 PVC conduit. It is designed to provide extra protection for electrical wiring in more demanding environments. The specifications for Schedule 80 PVC electrical conduit typically include a higher wall thickness, increased impact resistance, and the ability to withstand higher temperatures compared to Schedule 40 PVC conduit.
To properly connect PVC conduit to a metal box, you can use a PVC male adapter and a locknut. First, insert the male adapter into the end of the PVC conduit. Then, thread the locknut onto the male adapter and tighten it onto the metal box. This will create a secure and watertight connection between the PVC conduit and the metal box.
The conduit fill table for PVC pipes provides guidelines on the maximum number of cables or wires that can be safely installed in a PVC conduit based on its size. It helps ensure proper spacing and prevents overheating.

The wire fill chart for PVC provides information on the maximum number and size of wires that can be safely installed in a PVC conduit based on the conduit size.
PVC conduit is better then metal as it won't corrod under ground and theres less of a chance of electrical shortages.
