Re: soow cord on equipment
Per NEC Table 400.5(A), a #10 SOOW flexible cord (assuming 2 current-carrying conductors) is good for only 30 amps. But dana1028 is right: the only thing that really matters is the current drawn by the device. I cannot say what the manufacturer meant by declaring the tool to be ?rated for 40 amps.? But that is not the same as saying that the tool will draw 40 amps on a continuous basis while it is in use. If the device was tested, and is listed, for its present configuration, you have no cause for concern.
