Designed with EdrawMax, this template is an indoor electrical plan. The legend at the top right corner defines symbols like "INTEGRATED LIGHT", "DUPLEX SPECIAL PURPOSE OUTLET", "SINGLEPLEX RECEPTABLE", and "THREE-WAY SWITCH (S3)". The diagram shows the spatial arrangement of these electrical components within a room, with dotted lines indicating connections related to the three - way switches. This visual guide is useful for electricians, architects, or homeowners during electrical installation or renovation projects, helping to understand the placement and wiring of electrical fixtures in an indoor space.
