Square galvanized metal EMT electrical boxes are electrical enclosures used in electrical installations to house and protect electrical wiring connections, switches, outlets, or other electrical devices. These boxes are typically made from galvanized steel, which provides durability and corrosion resistance. Here are some key features and uses of square galvanized metal EMT electrical boxes:

1. Material: These boxes are constructed from galvanized steel, making them suitable for both indoor and outdoor applications. The galvanized coating provides corrosion resistance, ensuring the longevity of the box.

2. Mounting: These boxes are typically surface-mounted flush with a wall, ceiling, or other structural surface. They can be attached directly to wood or metal studs, concrete, or other surfaces using appropriate fasteners.

3. Knockouts: Many square metal EMT boxes have knockout holes on the sides that can be removed to create openings for conduit entry or to install cable clamps. These knockouts allow for flexibility in routing and securing electrical wiring.

4. Outdoor Use: Some square metal EMT boxes are designed for outdoor use and are constructed to withstand exposure to the elements, such as rain and UV radiation.

5. Cover Plates: To protect the wiring and connections inside the box and to provide a finished appearance, square metal EMT boxes are covered with appropriate cover plates or device covers, which can be made of metal or plastic.

6. Size: These boxes come in various sizes to accommodate different wiring needs and device types. The size is usually determined by the depth and dimensions of the box.
