1900 Electrical Box Specifications
Dimensions and Capacity
The 1900 box comes in two variants for different wiring needs.
- Standard 1900 Electrical Box: This version has dimensions of 4 inches by 4 inches with a depth of 1.5 inches. It can hold up to twelve 10 AWG wires. So, it suits moderate wiring tasks.
- Deep 1900 Electrical Box: It measures 4 by 4 inches and is 2.125 inches deep. The deep variant has more space for bulkier cables. It is more flexible for complex wiring.
These boxes are constructed from welded steel, ensuring robustness and longevity. They have slotted screw heads for easy installation. They also have multiple knockouts on the bottom and sides for 1.5-inch conduit sizes. The boxes can be used in circuits with voltages up to 600 volts. They are safe and meet industry standards, so no bonding jumper is needed.
Design and Features
The design of the 1900 box is both functional and innovative. A key feature is its patented design. It allows easy cable removal and connector reuse. This cuts the need for replacement parts during maintenance or upgrades. It saves costs and improves efficiency. Also, the knockouts are placed to support various conduit setups. This enhances the box’s adaptability in different installation environments.
Components of a 1900 electrical box
Knockouts:
Knockouts are pre-punched holes in a 1900 electrical box. These knockouts are easy to remove for adding electrical conduit or cables. They vary in size, usually from an inch to an inch, to fit different wiring needs. Simply use a screwdriver or knockout tool to punch out the needed size for a clean opening. This keeps the wires secure and organized. It also protects the system in the metal box.
Grounding Provisions:
Proper grounding is vital for electrical safety and NEC compliance. The 1900 box usually has a grounding screw or clip. Typically, the screw is inside the box. It securely attaches the ground wire, directing stray current safely. This action protects the system and prevents shocks and fires. Hence, grounding is essential in installation.
Covers and Accessories:
The 1900 box works with various covers and accessories. This makes it adaptable for different setups. Flat covers suit simple junction boxes. Raised covers are for devices like outlets or switches. Mud rings give a neat finish when the box is behind drywall or plaster. Mounting brackets secure the box to surfaces. Clamps hold cables or conduit. These components ensure safe, compliant installations and offer flexibility.
Historical Background: The Origin of the 1900 Electrical Box
The name “1900 electrical box” might suggest a link to size or capacity, but that’s a misconception. It actually comes from a part number given by the Bossert Company nearly a century ago. This fact showcases the 1900 box’s long-standing reliability and popularity in electrical engineering. It also highlights its continued importance in today’s installations.
Types of 1900 electrical boxes
Regular 1900 electrical box
The regular version of the 1900 Electrical Box is 4×4 inches with a depth of 1.5 inches. This version is ideal for basic electrical setups with minimal wiring. It is commonly used for standard light switches, outlets, and small lights.
