    What size Cable?
    We're installing a Built-In Microwave Oven Combo unit, with specs as follows: 40 Ampere, 208/240 Volts, 60 Hertz (1/second). AC-ONLY. USE COPPER WIRE ONLY. A FOUR-WIRE OR THREE-WIRE, SINGLE PHASE ELECTRICAL SUPPLY REQUIRED

    Question: The new unit is approximately 35 feet from the breaker box. What is the right size and type of cable to run to this unit?
