EMT is electrical metallic tubing. In the electrical trade there are nominal sizes expressed as a standard size. To answer your question you must state the conduit size in either electrical terms or in standard size terms to get a conversion size.
For example standard size 1/2" EMT has an actual diameter size of 3/4" and the 1/2"EMT connector for the 1/2" EMT conduit needs a 7/8" hole.
Likewise with 3/4" EMT the actual outside diameter is 15/16" and the 3/4" EMT connector needs a 1-1/8" hole.
A trade size hole for a 2-1/2" EMT conduit connector, the hole needs to be 2-7/8" in diameter. A 3" rigid conduit can also use this size hole without the lock nuts falling into the hole.
Back set for all conduit sizes is not the same. The greater the diameter of the conduit the length of back set increases. Without the diameter size of the conduit, an answer can not be given.

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
No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
A trade size hole for a 2-1/2" EMT conduit connector, the hole needs to be 2-7/8" in diameter. A 3" rigid conduit can also use this size hole without the lock nuts falling into the hole.
Yes 480 volt electric wiring can be run in emt conduit.
Back set for all conduit sizes is not the same. The greater the diameter of the conduit the length of back set increases. Without the diameter size of the conduit, an answer can not be given.
The recommended conduit size for a 200 amp service is typically 2 inches in diameter.
According to the 2005 NEC Annex C, table C.1 you are allowed nine #12 THHN conductors in a 1/2" trade size EMT conduit. If your conduit run is any length at all, you would be wise to increase the conduit size to 3/4". as pulling 9 #12's for any length in 1/2" EMT is very difficult.

The appropriate conduit size for accommodating 6/3 wire is typically 1 inch in diameter.

IMC conduit is thicker and heavier than EMT conduit, making it more durable and suitable for outdoor and industrial applications. IMC conduit is also more resistant to damage and corrosion. EMT conduit, on the other hand, is lighter and easier to bend, making it ideal for indoor and residential applications where flexibility is needed. In terms of benefits, IMC conduit provides better protection for wires and cables, while EMT conduit is more cost-effective and easier to install.
When exist a junction box EMT, conduit must be supported within 18 inches.
EMT conduit is made of metal and is more rigid, while PVC conduit is made of plastic and is more flexible. EMT conduit is typically used for indoor applications, while PVC conduit is better suited for outdoor or underground installations. The choice between the two depends on the specific needs of your electrical wiring project.
