Air Conditioner Wiring

A central air conditioner runs on 220 volts of electricity. A connection must be made between the main electrical circuit panel in your home and the condensing unit in order for the air conditioning to run. You can prepare the wiring for hook-up, but only a skilled contractor should complete the high-voltage wiring. Inexperience can cause electrical shock or damage to your equipment or property.

You will need to select the correct thickness of wire and corresponding breaker based on your condensing unit. Wires are rated by gauge. The higher the gauge number, the thinner the wire. Most residential AC units use 8 or 10-gauge wire. See the manufacturer’s spec sheets for more information. read more…
