Bank of eight 10 to 1 ratio step-down transformers supplying a 120 volts AC output!

This may be my best idea yet if I can make them larger myself or order some custom-made ones. I only need two to prove it is feasible!

On a 15A breaker the maximum power you can get out of a 120V outlet is 1800W (120V × 15A = 1800W). If you put all the transformer secondaries in parallel then you COULD get your desired 150A but only at 12V (12V × 150A = 1800W). If you put all 8 secondaries in series then you could get 96V at but only at 18.75A (96V × 18.75A = 1800W). If you added 2 more transformers then you could get back to 120V but only at the original 15A (120V × 15A = 1800W). There is no multiple-transformer arrangement in which you input 120V @ 15A (1800W) and get an output of 120V @ 150A (18,000W). That would break the laws of physics. Transformers increase *_voltage_* not *_power._* for every transformer-induced change in voltage, there is an equal and opposite change in current. None of this accounts for efficiency losses, which are substantial with such small transformers as you have found.
