An electrical plan shows the electrical symbols and wiring connections for a house. It includes the location of the meter, service box, light fixtures, switches, and receptacles. Considerations include placing the service box within 12 feet of the meter, mounting light switches by room entrances, and spacing receptacles every six feet. Smoke detectors are required in each bedroom, outside sleeping areas, and on each floor with at least one hardwired with battery backup. The plan defines symbols, shows wiring connections between devices, and can include other fixtures like phone jacks.

1. ELECTRICAL PLANSAn electrical plan is a plan view similar to the floor plan in that all the walls, doors, and windows are shown along with the electrical symbols that describe service to the house. It also includes what is known as a legend which defines what each symbol represents.There are several considerations that have to be made when drawing an electrical plan for a house. They are as follows:The Meter and Service box, Light Fixtures, Light Switches, and Receptacles

2. The Meter and Service BoxThe electrical meter is always on the exterior of the home. This is the location where power enters the house into the circuit box. The circuit box is located no more than twelve feet away from where the power enters the homes. From this location electricity is distributed to the individual rooms. The circuit box is usually located in a service area of a home like the utility room or kitchen. If the home has a basement, this is usually the preferred location for it to be placed.

3. Light FixturesLight fixtures are usually placed in the center of a room to allow even lighting throughout. Sometimes these are included in special fixtures like ceiling fans. When a fixture is placed in a large closet, it is usually mounted so that it is at least three feet from where the clothing is hung to insure against a fire from its heat. Exterior lighting should be waterproof in some way to eliminate the possibility of electrical short.

4. Light SwitchesThe light switches almost always are mounted next to a room entrance on the interior of the room for convenience. Switches should not be placed behind doorsWhen switching an exterior light, these are usually located inside near the exterior lights location.

5. ReceptaclesReceptacles, also known as outlets are usually spaced every six feet in a room. This is to make sure that electrical cords do not have to be stretched far from the appliance they are powering. Some times a homeowner requests that the top half of a receptacle be controlled by a light switch to make turning off lamps simpler. Exterior receptacles and those inside the house within six feet of a water source like a sink are ground fault interrupt. This is to eliminate possible shock if shorted by water.All of these are one hundred and twenty volt with a few exceptions and the amperage varies.

6. Wiring ConnectionsThese are usually drawn using a arched dashed line showing which switch controls what light or receptacle.There are many more considerations like two twenty volt power for appliances such as the stove or electrical clothes dryer. You may also place special fixtures like phone jacks and cable tv connections on this plan.

7. Smoke DetectorsThese are required by code for fire safety. They must be located in each individual bedroom and outside every sleeping area.A smoke detector is also required on each level of the house and near each exit from the home. These are usually battery powered so that even if the power is out, they will still function. At least one of the detectors must be hardwired into the house with a battery backup.
