Any Pointers on electrical layout for a fabrication rig
Former Community Member
Trying to find the best approach to this problem has the cable trays between the sockets of the units will not cater for large cables above 25mm2 so was looking at having to change the design from a looping cabling system between Main sockets on each floor there are 4 floors in total on the rig to each Power Cluster.So that each Power Cluster have there own Power Supply cable going to them individually so we can look at cutting down the size of cabling to fit the cable trays.But to do this i'm after some electrical layout ideas from the Forum.The starting point of the electrical layout are 3 125A Sockets (ie.400v,230v & 115v) which have an interconnection at two ends (ie Left Side and Right Side) so there is a need for a change-over switch.Then from there on looking at adding a large distribution box for the individual cables to connect to the various sockets of the Power Cluster.
This is a sketch of the layout of the Power Clusters on the rig.
That's bizarre (at least if I'm reading it right) - I presume the power is fed from the bottom and the rectangles above the "125A sockets" are plugs.
I hope I've mis-understood, otherwise you seem to have a ring circuits with a separate plug on the end of each leg of each ring - so if one plug was unplugged the exposed pins would be live from the other side of the ring (and I don't want to start imagining what would happen if one of the plugs was accidentally plugged into another circuit).
The separate 400V and 230V systems seem odd - it would be more usual to supply both from a 230/400V 3ph&N system (400V between lines, 230V L-N)
Likewise I'm a little surprised if 110V is distributed about the place - rather than having a transformer in each power cluster.
