A double-oven electric range is rated at 18 kW, 120/240 volts. Calculate the maximum demand according to Table 220.55. Show all calculations. For the range discussed in problem 1: What size 60°C ungrounded conductors are required? What size 60°C neutral conductor is required? What size 75°C ungrounded conductors are required? The terminal block and lugs on the range, the branch-circuit breaker, and the panelboard are marked as suitable for 75°C wire. What size 75°C neutral conductor is required? Terminations are the same as in part (c).

Most residential general lighting circuits are wired with 14-AWG copper conductors and are protected by 15-amp circuit breakers. However, there are many electricians who install 12-AWG copper conductors and protect them with 20-amp circuit breakers. How will you know which conductor size and which circuit breaker size will be used for the general lighting branch circuits in the house you are wiring?
