I live in Australia and I had my TV, blue ray player and oil heater plugged into a power board but after about 25 minutes the power board tripped and everything turned off. I know its because of the power/amps drain being too much so my question to fix this is to plug the heater into the second wall socket and the power board into the first wall socket as there are two sockets on the same wall power plug. Does someone know if a 2X socket wall power outlet is wired with a single cable or are they separate cables that way I can use the heater and power board separately and not worry of a problem like the heater causing over heated cables to the point of electrical fire as I dont have a second power board with a cut off mechanism at the moment.
