A G.I. Box typically refers to a junction box made from galvanized iron (G.I.). Here's a description:

1. Material: G.I. boxes are made from galvanized iron, which is iron or steel that has been coated with a layer of zinc to protect it from rust and corrosion. This makes the boxes durable and suitable for use in outdoor and harsh environments.

2. Design: G.I. boxes come in various shapes and sizes, including square, rectangular, and circular. They have openings or knockouts on multiple sides to allow cables to enter and exit the box. Some boxes have removable covers for easy access to the interior, while others may have hinged covers that can be opened and closed.

3. Uses: G.I. boxes are commonly used in electrical installations to house electrical connections, switches, outlets, and other electrical components. They provide a safe and secure enclosure for wiring connections, helping to protect against electrical hazards and prevent damage to the wiring.
