How to Run a New Electric Circuit from a Breaker Panel

※ Download: Hook up 220 breaker

I am installing two ovens, a 220v oven with convection and a 110v microwave with convection in a space where there used to be a combination two oven setup, regular 220v oven and 110v microwave on the same four wire circuit, black, red, white and bare ground. The center white conductor is connected to the center screw of that dryer connecting block. What this means is that the breaker will take the power from the panel by the two very different phases.

Main Breaker Panel | 220 Volt & 110 Volt Metal Electric Panel - Some jurisdictions require you to be an electrician to perform any electrical work, even in your own home.

Most of the circuit breakers in a typical residential panel control 110-volt circuits, but every panel usually also has at least one 220-volt breaker. This type of breaker consists of two stacked 110-volt breakers and because of this, it's often known as a double-pole or two-gang breaker. Installing one isn't much more difficult than installing a 110-volt breaker. But because of the potential for serious shocks, a typical homeowner shouldn't try to do this or, for that matter, do any other type of work in the panel. Working in the panel is a job for a licensed professional. Because of the higher voltage, 220-volt circuits conduct more current, so to prevent overheating, you need wires with a larger diameter than you do for 110-volt circuits. The minimum wire size is 10-gauge, but appliances that draw 50 amps, such as stoves, require 8- or 6-gauge wires. You also need an extra hot wire, so the cable includes two, which are usually colored red and black. A 220-volt cable includes neutral and ground wires, and are usually designated three-conductor cables because the ground wire doesn't count as a conductor. Before you buy a breaker, check the brand on the panel and make sure the breaker you buy is the same brand. Although the principles of 220-volt wiring don't change from brand to brand, the panel and breaker designs do, and breakers are not interchangeable among manufacturers. Older homes may have panels with other brands, such as Zinsco-Sylvania or Federal Pacific. Although these are now outdated and possibly dangerous, you still need to use the breakers that fit them until you replace the panel. Before installing a 220-volt circuit, check the panel to make sure you have two slots next to each other to accommodate the breaker. The black hot wire connects to one of the breakers in the two-breaker set and the red wire connects to the other one. The white wire goes on an available lug on the chrome neutral bus and the ground wire goes on the ground bus. It's easy to identify these bus bars because they already have a number of white or bare wires connected to them. Once you've made all the connections, you'll install the breaker by inserting one end into the slot and pushing down on the other end until the breaker snaps into place.

I live in mobile home park. Later I flipped the breaker for the water heater and within 10 minutes the outside main off again?? Then I have to put the junction box at the end because I plan to extend with solid wire 12-2 gauge that run into my Japanese tea house from the backyard with 3 outlet and one light. Most of the breakers will have a 15-amp rating. In 3-conductor connections, there is no red wire. I am building a new home.
