I want to limite the amount of current a appliance could draw to 12A in order to use it on a 15A outlet without tripping the breaker.
I have a HeatPress (heating element(coil) with a PID controller) working on 120VAC rated 15A with a T-Brace plug for 20A outlet. Link to Heatpress website spec
The previous owner told me he add a electrician make him a adapter cable with a box in the middle to be able to plug in it a 15A outlet without tripping the breaker.(but it was nowhere to be found)
I think I must keep the voltage to 120V to make the PID and maybe other electronic component happy so I dont think a variac can be the answer.
Common theorical sense told me to raise the resistance from 8Ω to 10Ω
120V 15A 8Ω 1800W / 120V 12A 10Ω 1440W
But adding in serial a 2Ω 1440W if I'm right sound in my head like a joke.
So here I need your help, what was in that boxe? Is it possible to limit the current the appliance can draw? I know the heating element will take more time to heat and wont be able to be as hot but that's not a problem for me.
Thank You for you time
