In this context, ‘low-voltage .Consequently, a LV-PCB can be programed to delay tripping in order to give downstream circuit breakers a chance to clear the fault first. Hence, low-voltage switchgear with power circuit breakers can be used to greatly improve the reliability of a power distribution system. A properly coordinated system can also increase worker safety because .If an adjacent customer switchroom is required (LV or MV), it shall be sited adjacent to the MV substation room. It shall comply with the ode of Practice for the ustomer Interface. The customers main ci rcuit breaker should be located so that the feeder cables can run directly from the ESB substation duct, through the boundary wall at the
Figure 2 – Busbar Compartment (Rear Side of an LV Panel) Go back to the Contents Table ↑. 1.3 Cable Compartment.
