An electrical plan is a detailed drawing of all outlets, lights, and switches in a house. The plan will show the location of the outside electrical service, inside panel, and any disconnects. Three way switches will be noted along with any switched receptacles. The location of all lights will be shown and it should note if there will be any specialty switching such as dimmers.

Other items that should be shown on an electrical plan are GFI receptacles, outside receptacles, dryer or stove outlets and any specialty receptacles such as for sight and hearing impaired. The overall plan should give a complete view of everything pertaining to electrical items in a house. The electrical plan should contain an electrical symbols list. This will show each electrical symbol and what it means.
