＂Rack and Stack＂ Grounding Construction
Grounding is an important component of any electrical system. It helps protect equipment from lightning, current spikes, and reduce the possibility of electrical surges. Without it, any electronic component would be exposed to potential damages from electrical disturbances. To ensure it works properly, it is essential to install it properly. One of the most common ways to install grounding systems is the “rack and stack” grounding construction method.
The rack and stack method of grounding construction involves assembling several components in an orderly manner. It is often used in a variety of settings, from large-scale industrial facilities to smaller residential ones. The first component of the installation is usually a grounding bar or frame. This typically includes a ground busbar, a grounding electrode, and several connecting bolts. This bar or frame is then attached to a buildings foundation or wall using U-bolts and lag screws.
Once the grounding bar or frame is installed, a grounding conductor is connected between the frame or bar and the equipment being grounded. These conductors are often split into two or more runs, depending on the size and scope of the grounding system. The runs are typically made using stranded steel, bare copper, or insulated aluminum.
The next component of a rack and stack grounding construction is the splice and tap. This is a device that is designed to be used to join together two or more conductors. It is designed to protect the conductors from damage and to keep the integrity of the grounding system in place. The splice and tap is usually connected to the grounding bar or frame that was previously installed.
Finally, the grounding conductor is attached to the equipment being grounded. This can be done with a clamp or screw connecting the conductor to the equipment. This tightly secures the conductor to the equipment and helps to prevent it from becoming a potential hazard. Once the connection is made, the grounding system is then inspected and tested.
The rack and stack method of grounding construction is an effective and reliable way of installing an electrical grounding system. It provides a secure connection between the equipment and the grounding frame or bar and helps to protect the equipment and all connected components. It is also relatively inexpensive and easy to install, making it an ideal choice for many electrical installations.
