A house wiring diagram is a visual representation of the electrical system or circuit in a house. It shows how the wires are connected and where the outlets are located, as well as the actual connections between electrical components. If you are looking for a wiring diagram for your house, you can try contacting the builder or the inspections and permits office. You can also try creating your own diagram by listing every light, receptacle, and hardwired electrical device in your house, and which breaker controls it. Alternatively, you can use a voltmeter or a circuit tracer to detect the wires and their connections.

What You'll Learn
Contact the builder or the county
If you are looking for an electrical diagram for your house, there are a few options you can try. One option is to contact the builder of your house. They may have an electrical drawing or blueprint that shows the location of outlets, switches, and connected lighting/appliances on each circuit. However, it is unlikely that this will detail how the wires are routed through the walls. Keep in mind that if your house has changed hands since it was built, the original builder may not be the best source of information. In this case, you could try contacting the previous owners to see if they have any information about the electrical setup.
Another option is to reach out to your county office. In some cases, the builder submits electrical drawings to the permits or inspections office, so they may have the information you need. Your county may also be able to find the original drawings for you for a fee.
Alternatively, you could try creating your own electrical diagram. Start by making a list of every light, receptacle, and hardwired electrical device in your house, along with the corresponding breaker. You can then create a map of your home's electrical system by turning off all the breakers except for one and then finding everything that still works. Repeat this process for each breaker to gain a comprehensive understanding of your electrical setup.
If you are experiencing issues with your electrical system and need to troubleshoot, there are a few options available to you. One simple method is to use a voltmeter to detect electricity in the outlets. You can also hire an electrician to help diagnose and resolve any issues. Some electricians may offer alternative solutions, such as wiring in a second installation, to address the problem.

Check with the inspections and permits office
If you are looking for an electrical diagram of your house, it is recommended to check with the inspections and permits office. The office responsible for overseeing electrical inspections and permits will vary depending on your location. For instance, in the State of Colorado, the Colorado State Electrical Board conducts electrical inspections in areas that are not inspected by local authorities, such as public schools and state buildings. On the other hand, the City of Chicago's Electrical Inspection Bureau enforces the safe installation of electrical wiring and equipment, working closely with electrical contractors and building owners to ensure compliance with the city's electrical code.
Now, if you are a resident of Colorado, you can refer to the contact information provided by the State Electrical Board of Colorado. Their office is located at 1560 Broadway, Suite 1350, Denver, CO 80202. You can reach them by phone at 303-894-7800 or by fax at 303-894-2310. Email communication is also available at [email protected].
For those living in Chicago, you can refer to the Electrical Inspection Bureau, which is responsible for conducting inspections and ensuring the safe installation of electrical wiring and equipment. They recognize any nationally-recognized testing laboratory listed on the OSHA website.
Additionally, if you are located in Washington, you can refer to their specific guidelines. Electrical work in Washington typically requires a permit and inspection, although there are certain exceptions. To determine if your work necessitates a permit and inspection, refer to Chapter 296-46B-901 WAC. Permits must be purchased by the electrical contractor, property owner, or homeowner performing the work. It is important to obtain the electrical permit and inspection from the appropriate jurisdiction, whether it falls under a city with its own permitting process or within Tacoma Power's service area.
By reaching out to the relevant inspections and permits office in your area, you can inquire about obtaining electrical diagrams for your house. They will be able to provide you with specific information and guidance on acquiring the necessary documentation.

Use a voltmeter or a circuit tracer
A voltmeter is a highly useful device for home electrical testing. It can be used to detect a lack of electricity in outlets, and to test voltage. Before using a voltmeter, it is important to learn how to set up the device correctly and test it out on a low-voltage circuit such as a household battery. To use a voltmeter, attach the positive terminal to the positive end of any circuit, and the negative terminal to the negative end of the same circuit. Ensure that you do not touch the metal probes while connecting them to a circuit. If the insulation looks worn or torn, wear electrically insulated gloves or purchase replacement leads. The two metal probes should never touch each other while connected to a circuit, or severe sparking could occur.
To test the voltage of an AC circuit, set the knob to V~, ACV, or VAC. To test the voltage of a DC circuit, set the knob to V–, V---, DCV, or VDC. Household circuits are almost always AC, whereas batteries and portable electronics are typically DC. Choose a range above the maximum expected voltage to avoid damaging the device. If you have no idea what to expect, choose the highest setting. Household batteries are usually labelled with the voltage, typically 9V or below. Raise the range if you get an overload reading. If your device has no range option, it is "autoranging" and should detect the correct range itself.
Circuit tracers are another tool that can be used to locate electrical wiring behind walls and underground. They work by sending a tone down the line, which can be traced with a small receiver. To use a wire tracer, connect the transmitter through a test lead or current clamp. For most applications, a direct test lead connection will give the best results. Connect the red and green test leads to the transmitter, and then connect the red test lead to the hot wire on the load side of the circuit. Finally, connect the green test lead to a separate ground, depending on the type of circuit. Once you've made the connections, turn on the transmitter. Depending on the voltage present, an advanced wire tracer will automatically select energised or de-energised mode. Keep the receiver at least 3 feet away from the transmitter to minimise signal interference. Move the receiver along the wall to find the highest signal level, which indicates the presence of the wire.
