Hi guy and gals, Im an electrician that has started in a hospital and have been tasked with changing a distribution board.
Thry are currently old type 3 3871 mcb, and I was going to change them for 32 Amp rcbo type c rated, 30mA . The circuites are mainly ring mains, that cover patient rooms.
The equipment plugged in would be beds with motors, medical equipment with pumps, and other portable appliances. I am worried as the ZS values of the circuits are higher than the MCB values. Or would the Rcd cover this ?
Any thoughts would be great.
