This is a hand-drawn electrical schematic diagram illustrating a multi-floor building electrical distribution system. The diagram depicts an electrical infrastructure consisting of a main electrical panel located in the basement that distributes power to three separate electrical panels serving different floors of the building: the second floor, first floor, and ground floor. The main service originates from a "Breaker at basement" (shown in red annotation on the left side) and connects to a "Main Electrical panel in basement" (labeled in red at the top center). Three numbered electrical lines (marked 1, 2, and 3) branch from the main basement panel, each with corresponding circuit breakers for protection. These lines extend horizontally across the diagram to supply power to three downstream electrical panels positioned at progressively higher elevations. The electrical lines are color-coded in green text labels, and each serves a specific floor's panel: line 1 supplies the second floor electrical panel, line 2 supplies the first floor electrical panel, and line 3 supplies the ground floor electrical panel. The diagram also indicates an electrical connection between the main panel in the basement and the upper-floor panels through a series of electrical lines. This appears to be a preliminary design sketch used to document the electrical distribution network for a three-story building structure.
