All conduit shall not have more than 360 degrees for it's length between either a box, cabinet, or conduit body. Couplings count as a continuation of conduit.

This is per the NEC Handbook, 2005 edition. Your municipality may use different rules. I am not an electrician. Per Table 5, chapter 9: Approximate area of 14 ga. THWN is 0.0097 sq. in. Approximate area of 6 ga. THWN is 0.0507 sq. in. 0.0097 * 3 = 0.0291 0.0507 * 4 = 0.2028 ...total area 0.2319 sq. in. Per table 1 chapter 9, you are allowed 40% fill for more than two wires in EMT. So, 0.2319 / 0.4 = 5.7975 sq. in. minimum conduit area, which means you'd have to use 2-1/2 inch trade size EMT, which is 5.858 sq. in. Hope this helps.
To strip electrical wires and to twist mutliple wires together.
No, non-metallic cable (such as Romex) cannot be used in electrical metallic tubing (EMT) conduit. EMT is designed to house and protect electrical wiring, so it is meant to contain only electrical wires, not non-metallic cables. It is important to use the appropriate type of wiring for the specific conduit being used.
Strap the conduit every five feet.
EMT can earn anywhere from 42000 and 72000 dollars a year. You will need 2 years of basic emt training which can be earned at many universatries.
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.
EMT stand for Intermediate practice exams. These practice tests are only to demonstrate the type and quality of EMT. I questions that can be found within our subscription area. These EMT I exams do not include the grading and rationale functionality as do the exams within the paid members area.
