Collaboration: Zarzą[email protected] Network systems are simply a method of powering electrical installations, grounding these installations, and, consequently, providing protection against electric shock. The network layout also determines how many conductors are run in the installation and their role in the overall system. There are five AC network layouts: TN-C, TN-S, TN-C-S, TT, and IT. Choosing a layout is a compromise between safety, cost, and network operability. TN is common in residential buildings due to its simplicity, TT provides grounding independence, and IT increases reliability at the expense of more advanced insulation protection and monitoring.
