· You know what M.D. means, but what does D.O. mean? What's different and what's alike between these two kinds of health care providers? The breakerpanel, or electrical box, serves as the connection between the local power grid outside the home and the wiring inside the home. This panel can control the flow of electricity, allowing you to turn off the electricity to the entire house with a single switch. Here’s a breakdown of what theswitcheson your breakerpanelmean and how they protect your home.The largest switch at the top or center of your breakerpanel is the main breaker. This switch controls the power supply for your entire home. Flip the main switch for the whole house, and it’s (literally) lights out. Whatdothe numbers on your breakerpanelmean? Breakers have limitations: you can’t run unlimited amounts of electricity through them and into your home. A double pole breaker looks like two single breakers joined together. It connects to two “hot” wires at the same time. This setup allows it to provide 240 volts. Because it connects to two bus bars in your panel, it takes up two slots. You will see a plastic bar connecting the two switches. 1. Before working inside the panel, switch off the main breaker to cut power to all branch circuits. Verify there’s no voltage using a non-contact voltage tester. 2. Identify the cable in 120V/240V main panel. Identify the main breakerswitch, which is usually at the top or bottom of the panel.Switch the main breaker to the "off" position by flipping it to the opposite side.Use a voltage tester to ensure that there is no power running to the panel. Interpreting Switch Positions: Breakerswitches can be in one of two positions: “ON” or “OFF.” The “ON” position means the circuit is active, while “OFF” means it’s disconnected. In some panels, a tripped breaker might be in a middle position, indicating it has tripped but can be reset. The breakers are both 20A switches. In the picture, they are right below the 100A switchon the top right. UPDATE: I removed the front panel from the breaker box and took some pictures . UPDATE 2: found out that the clothes washer is also on this circuit. Read the information on the panel label. it will say something like 20-40, or perhaps 20-30, etc. How many circuit breakers are in place now? Do not count the main breaker, and count each 240 volt breaker as two. See what loads the 2 switches control and maybe you can use one power source, abandoning in place the other, cap the wires and disconnect the breaker. When I bought the house, the first thing I did was replace ALL wiring and panel. Electrical breakerpanels are complicated and best serviced by professionals only. What Different Sounds Coming From Your Electrical PanelMean. When you switchon the central heating or cooling system, the power in your home goes to the circuit breakers. Then simply switchon the remaining breakers one at a time untill the earth Leakage trips. This circuit breaker is now where your fault lies. If it's a plug breaker, simply unplug all appliances and try again. A tandem breaker is the same size as any other standard, or single-pole, breaker but it has a key difference. Each has its own toggle switch, and the breaker snaps into the panel just like a regular breaker. A tandem breaker supplies two separate 120-volt circuits. This breakerpanel was installed in a home I inspected last week. Notice the 120v 100 amp main. Any comments? Also some circuits are AL.P.s. the AC unit does not have a disconect switchon the exterior. I called out an electrician but just wanted some extra info. Hence this post.
