To determine how many 1250 kcmil (thousand circular mils) conductors fit in a 4-inch EMT (Electrical Metallic Tubing), we first need to find the allowable fill capacity based on the National Electrical Code (NEC). A 4-inch EMT can typically accommodate up to 100% fill of 1,000 kcmil conductors, which is about 14.5 cubic inches per conductor. Since 1250 kcmil conductors have a larger size, typically, only one 1250 kcmil conductor can fit in a 4-inch EMT due to fill and bending space limitations.
In a three-quarter inch EMT conduit, you can typically fit up to 9 number 10 THHN wires, according to the NEC (National Electrical Code) guidelines. However, this number can vary depending on factors such as the type of insulation and installation conditions. It's always best to consult the NEC tables or a qualified electrician for precise calculations tailored to your specific application.
The number of 12-gauge wires that can fit in a three-quarter inch conduit depends on the type of conduit and the specific application. Generally, for a three-quarter inch EMT conduit, you can fit about 9 to 10 number 12 wires, following the National Electrical Code (NEC) guidelines for conduit fill. It's essential to consider derating factors and any additional requirements based on the installation conditions. Always consult the NEC or a qualified electrician for precise calculations.
When using a 1-inch EMT bender, you typically subtract 2 inches from the total length of the conduit for each bend. This accounts for the radius of the bend, which is usually 3 inches for a 1-inch EMT bender. Therefore, if you are planning to make a bend, measure the distance you want to bend from the end of the conduit and subtract 2 inches to ensure the proper length.
In a three-quarter inch EMT (Electrical Metallic Tubing), the maximum number of 12 AWG THHN conductors allowed is typically 10, according to the National Electrical Code (NEC) guidelines for conduit fill. However, this number can vary based on factors such as the specific application, bundling, and ambient temperature. It’s always important to consult the current NEC code and local regulations for accurate requirements.

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.
