A GI (galvanized iron) modular box size list is a document that specifies the dimensions and configurations of various sizes of GI boxes used for electrical installations. These boxes are typically used to house switches, sockets, and other electrical components in a concealed (flush-mounted) or surface-mounted manner. Common sizes and types:

• 1/2 Module: Smallest size, often used for single switches or small components. 
• 3 Module, 4 Module, 6 Module, 8 Module: Common sizes for multiple switches and sockets. 
• 12 Module, 18 Module: Larger sizes for more complex installations or multiple components. 
• Horizontal (H) and Vertical (V) configurations: Indicate the orientation of the box within the wall. 
• Surface boxes: Designed to be mounted on the surface of the wall, rather than being concealed within. 
• Concealed boxes: Designed to be installed within the wall cavity. 

Key features to look for:

• Material: Typically made of galvanized steel for corrosion resistance and durability. 
• Gauge: Refers to the thickness of the metal sheet (e.g., 18 gauge, 20 gauge). 
• Dimensions: Measured in millimeters (mm) or inches, including length, width, and depth. 
• Module count: Indicates the number of standard electrical switch/socket modules the box can accommodate. 
• Voltage rating: Specifies the maximum voltage the box is designed to handle (e.g., 230V). 
• Finish: May be powder-coated or have other protective finishes.
