Determine if it is economically feasible to install number 10 (AWG) copper conductors instead of number 12 (AWG) on a 400-ft branch circuit that feeds a load of 16 amperes. Assume that:

• The load is used 10 hours/day and 250 days/year.

• The cost of electricity is $0.10/kWh.

• The installed costs of No. 12 and No. 10 conductors are, respectively, $60.00 and $90.00 per 1,000-ft long cable.
