What is the minimum size EMT needed for a combination of six 1 AWG, eight 2 AWG, and four 1/0 AWG THW conductors?

Explanation:
To determine the minimum size EMT (Electrical Metallic Tubing) required for a combination of conductors, we need to calculate the total cross-sectional area of the conductors and then refer to the NEC (National Electrical Code) guidelines for conduit fill. 1. **Calculate the cross-sectional area of each type of conductor**: - 1 AWG THW conductor has a cross-sectional area of approximately 0.1257 square inches. - 2 AWG THW conductor has a cross-sectional area of approximately 0.0785 square inches. - 1/0 AWG THW conductor has a cross-sectional area of approximately 0.1671 square inches. 2. **Multiply the number of each conductor by its respective cross-sectional area**: - For six 1 AWG conductors: \( 6 \times 0.1257 \) = 0.7542 square inches. - For eight 2 AWG conductors: \( 8 \times 0.0785 \) = 0.628 square inches. - For four 1/0 AWG conductors: \( 4 \times 0.1671 \) = 0.6684 square

To determine the minimum size EMT (Electrical Metallic Tubing) required for a combination of conductors, we need to calculate the total cross-sectional area of the conductors and then refer to the NEC (National Electrical Code) guidelines for conduit fill.

  1. Calculate the cross-sectional area of each type of conductor:

  • 1 AWG THW conductor has a cross-sectional area of approximately 0.1257 square inches.

  • 2 AWG THW conductor has a cross-sectional area of approximately 0.0785 square inches.

  • 1/0 AWG THW conductor has a cross-sectional area of approximately 0.1671 square inches.

  1. Multiply the number of each conductor by its respective cross-sectional area:

  • For six 1 AWG conductors: ( 6 \times 0.1257 ) = 0.7542 square inches.

  • For eight 2 AWG conductors: ( 8 \times 0.0785 ) = 0.628 square inches.

  • For four 1/0 AWG conductors: ( 4 \times 0.1671 ) = 0.6684 square
