THW-A aluminum wire 10 sq.mm is a single-core wire with an aluminum conductor and black PVC insulation, rated for up to 750 volts and a 70°C conductor temperature under TIS 293-2541. This size is mostly used as the service drop from the utility pole to the meter and main panel of homes, townhouses and small shophouses.
Under TIS 293-2541, THW-A 10 sq.mm carries up to 50-52 A continuously in free air. In conduit, in bundles or at high ambient temperature the usable current is lower, so have an engineer or electrician size the wire from the load and run length (voltage drop) before you order.
