Inside of an Electrical Room (ER) there are MV and LV equipments. Is it correct joining the ground bars of MV and LV circuits?
Inside of an Electrical Room (ER) there are MV and LV equipments. We use a Cu bar of 50x10to ground the LV circuits and another bar of 50×10 to ground the MV sistems. My design is that the LV ground bar do not be connected between them; each one must be connected directly at the earth mesh. But my customer wants to install a perimetrical bare cooper wire around the ER, and it must connect the LV ground bar and the MV ground bar. Is it correct??
