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.
The scenario is that the bigger cables that are looped in between the Power Clusters will require big bend radius and the total current capacity at anyone time should be under 100Amps (ie 4 Welding Machines) which in essence could a cable of 25mm2 cope ok with. But if each Power Cluster is connected with individual power requirements could reduce the cable size down even more if connected via a distribution box.The 125A Sockets (these being the biggest sockets we can gain commerically) are for the incoming power requirements from the outside Main Power Supply (which has a maximum Power requirement of 250A) to the Rig.Jimmy
