Hi can anyone advise me. My company have installed a dimming rack ( from USA ) it's a 0-10 v dmx system . It's 3- phase and protected by 3- phase B 20 amp 60898 but on the dimmer rack it has 24 x C10 amp 60898 but they only have a breaking capacity of 3 KA my Pfc reading is 2.9 so it exceeds the B/C as the main 60898 has B/C of 10 K/A is this covered I know under fault condition the dimmers can melt but it will trip through main mcb . Where does that leave me with certification ? Can anyone help please
