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.
Loads in total at anyone time would be 4 Welding Machines each producing 16kW of power so in total about 92A.Then there are Milling and Cutting Machines but these won't be used while welding is being done.There is a Crane on the top floor but this produces maximum of 20A this is the 400v system.The 200v system is for the office on the ground floor containing 12 32A Sockets with 4 on the left side and 9 on the right side with workbenches either side and lighting comprising of 12 26W lights and a single light in a changing room.There is presently nothing being used on the 110v system but client wants a requirement.
