A normal 15A house wiring can hold ~3450w and so, if you are careful you can probably manage 2500w per socket.

But a typical bangalore home has 3kva load (instead of 5) officially and if you exceed it, it can be there on the bill and the BESCOM(or any COM) may demand explanation. Did anyone face the situation? Did they charge penalties (you can also PM if don't want to discuss here)
