Determine the required EMT size for the following combination of conductors:18. Four 8 AWG Type THW and four 12 AWG Type THW:19. Three 350 kcmil and one 250 kcmil Type XHHW conductors and a 4 AWG bare conductor:20. In a nonmetallic-sheathed (Type NM) cable installation, a 10⁄3 with equipmentgrounding conductor is installed in a metal octagonal box to supply two 12⁄2 withequipment grounding conductor branch-circuit cables. What is the minimum sizebox? The box contains internal cable clamps
For problems 8 and 9, determine the correct box size for each of the following conditions:8. Two nonmetallic sheathed cables with two 12 AWG conductors, an equipment groundingconductor, and a switch in a metal box without a plaster ring.9. A raceway run serving a series of luminaires, connected to a total of three circuits. Theluminaires are supplied by 120 volts from a 3-phase, 4-wire system. Each box will containtwo circuits running through the box and a third circuit connected to a luminaire, which issupported by a luminaire stud in the box. Use 12 AWG Type THHN conductors.
