If I had to do this my first thought (other than should I) would be to use a welder as a power supply.
A welders output could easily be used to overload 15 amp branch circuit wiring.
They operate at a relatively safe voltage and the current can be controlled.
Not that
I ever tortured some wiring components with a welder.
