The electrical supply of the crane must be from the DB box in the hall. So we expect that the DB box is transported together with the crane structure.  This means that  this DB box needs to be designed already. Please send a concept design drawing of the DB box.
For the design of the DB box the next points need to be incorporated.   1. One isolating switch per skid (incl. instrumentation), to be operated without opening cabinet.   2. One overall emergency switch, to be operated without opening cabinet.   3. spare groups/capacity for future additional electrical panel.   4. spare groups/capacity for future additions.   5. Electrical supply (400 V, 400 A) to DB box is foreseen as 2 cables coming out of the floor. Please indicate the necessary overlength for these cables.   6. The location of the DB box in the hall is in the corner next to the electrical panel, please confirm this location.
