Wire gauge refers the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter. Which I install accordingly instead of the 2pole30. Use a contact voltage tester on the wires inside your circuit breaker box to see if they still have power if you want to double check if they have a current through them. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The MAC label on the actual unit specifies 30A; thus, a 10 ga. wire is necessary along with a 2-pole 30A Siemens circuit breaker. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. A neutral wire isn’t utilized within this circuit. Important: This is a general guide, never exceed 80% of the amphere rating. The label on the air conditioner says "Cooling Amps 15.0/16/5," which would lead me to believe that the wire is sufficient for the load. For years now I run 10/2 to my AC condensers on a 240v 30a breaker.

This is a 220v 20 amp outlet as shown in the how to 220-volt outlet video likely to be used this for larger power tools in your garage or shop or perhaps a wall air conditioner. The table below is for 12-volt ac or dc devices only. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F). Please consult the National Electric Code (NEC) and any applicable local standards for exact requirements. You can buy outlet boxes from your local hardware store. Each side is 120 volts, and both sides together are 240 volts.
