Home / Does the third-level distribution box need to be closed
Further, the loads must be shut down to perform maintenance on the system. This arrangement is most used where the need for low first-cost, simplicity, and space economy outweigh the need for enhanced reliability. "Two level protection" mainly refers to the use of leakage protection measures. Moreover, power and lighting switch boxes must be set up separately—there shall be no shared enclosure with separate branch circuits.
