Please answer all questions and give me a sample answers, 1- What determines the ampacity of a wire? 2- When armored cable is used, what protection is provided at the cable ends? 3-A 120-volt branch circuit supplies a resistive heating load of 10 amperes. The distance from the panel to the heater is approximately 140 ft. Calculate the voltage drop using (a) 14 AWG, (b) 12 AWG, (c) 10 AWG, (d) 8 AWG copper conductors. See 210.19(A), Informational Note No. 4 and 215.2(A)(3), Informational Note No. 2. 4-In problem 3, it is desired to keep the voltage drop to 3% maximum. What minimum size wire would be installed to accomplish this 3% maximum voltage drop? See 210.19(A), Informational Note No. 4 and 215.2(A)(3), Informational Note No. 2. 5-NEC 215.2, 220.61, 230.42, and 310.15(B)(7) state that the neutral conductor of a residential service or feeder can be smaller than the phase conductors, but only 6-The allowable ampacity of a 4 AWG THHN from Table 310.15(B)(16) is 95 amperes. What is this conductor’s ampacity if connected to a terminal listed for use with 60°C wire 7-Most armored cable today has 90°C conductors. What is the correct designation for this type of armored cable? 8. If you saw two different types of SE cables, how would you distinguish them? 9-Flexible liquidtight metal conduit will be used to connect the air-conditioner unit. It will be trade size 3⁄4. Must a separate equipment grounding conductor be installed in this FLMC to ground the air conditioner properly?
