Show the calculations to determine the minimum size Type THHN conductors and the rating of the overcurrent

Show the calculations to determine the minimum size Type THHN conductors and the rating of the overcurrent protective device (fuses) for the circuit supplying the boiler. Use two conductors per phase in two raceways. Also determine the size of the equip- ment grounding conductors to be installed in each raceway. The expected maximum temperature in the room where the boiler is located is 100F (37.8C). The boiler elec- trical panel and the distribution panel are rated 75C. All conductors are copper.
