    24VDC Power supply units - 0Volt earthing

    Is it recommended to connect all zero volt lines from separate 24VDC power supplies to earth, thus ensuring all zero volt lines are at the same potential? And what if there is only one source of 24VDC power in the electrical panel, should the 0 volt line be connected to earth? Thanks

    AC Motor Braking

    I need to select a braking unit for my 415V 37KW 3phase induction motor. I have been told that a general rule of thumb for calculating the maximum braking current is 4*KW. This gives me ~150A. So i should select the next size unit. Is this correct, and does anybody have a more technical solution...
