Hi ARL02. My own experience of this is that the electrical supply for the temporary cabins varied depending on the project and the existing infrastructure. For a renovation project of an existing building, we provided three separate single-phase 32A supplies for the cabin, the office, and the toilet block. For a hospital extension project, we provided one three-phase 200A supply for all the cabins and shower blocks. The specification of the electrical supply was usually determined by the principle contractor who was responsible for the CDM.
