You've got 400V between phases going on in loads of other OB kit, that in reality people are more likely to open up for whatever reason, such as dimmer packs, distro, etc.Hello, This is to provide a safe working enviroment. We dont need the possibility of 400v across two PSU's running on different phases, why take the risk? It is the preferred practice within Broadcast systems to have dual supplies within a piece of kit to be fed from two UPS systems (main and back up ) BUT on the same phase.
