Circuit Breaker Panel Diagram
The following electrical engineering diagram is done through the edraw engineering diagram program.
Circuit breaker panel diagram. Make a list that you can post on the inside of the door. The hot wire for a branch circuit is connected to the breaker by a set screw on the base. If the circuit breakers aren t already numbered inside the electrical panel number them. Click on the circuit breaker to release the switch.
Every permanent electrical device in your house is connected to a circuit that is controlled by a circuit breaker in your breaker box properly known as the main service panel when you need to shut off the power to a circuit or to reset a breaker that has tripped you have to find the right breaker for the circuit this is about the time you begin cursing your home s builder for failing to. The 15 amp and 20 amp breakers often handle baseboard heaters 30 amp serve water heaters and electric dryers 40 and 50 amp are for electric. A service panel is a steel box with a hinged door or lift up panel on the front. In a new home construction or a rewiring project the last step will be connecting all the wires to the circuit breaker box which is what this article describes.
Panel templates are an essential facet of programming. Panel programming formats are ideal for people looking for something specific. Grounding in the maze of wires that inhabits your breaker box there s one more to be. This diagram illustrates some of the most common circuits found in a typical 200 amp circuit breaker service panel box.
The ideal way to understand the wiring diagrams is to examine some examples of wiring diagrams. Typically one panel feeds the entire house but there can also be another smaller panel called a subpanel which may be used to serve a specific area such as an addition a large kitchen or a detached garage. When you must disconnect the capacity of a circuit or reset a switch that has tripped you must find the most appropriate circuit breaker. Numbers should correspond to each circuit breaker.
Some circuit breakers use an explosive charge to throw the switch. Uses the entire 240 volts available to the panel. When current rises above a certain level it ignites explosive material which drives a piston to open the switch. 8 gauge wire goes with 40 or 60 amp two pole breakers.
The breakers are installed in a panel so that contact is made with one of two hot bus bars running down the middle of the box. A bimetallic strip design works on the same principle except that instead of energizing an electromagnet the high current bends a thin strip to move the linkage. Twelve gauge wire suits 15 to 20 amp breakers. Though the following instructions refer to circuit breakers the same procedure applies to panels that utilize fuses.
