A common problem for resistive loads, like household heating appliances, is that peak current is drawn on startup.
I have come across ICLs (inrush current limiters), which are cheap components. Do they solve the peak cold-start problem? If so, is there some other reason why they aren't frequently or always used in household resistive heating appliances?
Aside from the startup phase, I am wondering if "intelligent" (but still, household/countertop-level) appliances can be equipped with other countermeasures to overloading whatever circuit they're connected to. For example: is it possible to sense or infer line load? Perhaps based on voltage variations? And if so are there any common current-limiting components that can be put on a 120V 15A device to modulate its load in response to circuit conditions?
Original question, closed presumably due to the distracting example, but left here so the previous comments and answers make sense:
I have a toaster and coffeemaker – two resistive loads – on the same kitchen circuit. My old coffeemaker would trip the circuit if run together with the toaster. A new coffeemaker heats water even faster but does not trip the circuit when run with the toaster.
So is there a way that such a household device can intelligently regulate its current consumption to avoid overloading a circuit?
E.g., is there some reliable line indication that it is being overloaded, like a drop in voltage?
And is there any other common current-limiting component that can be put on a 120V 15A device to react to any line feedback?
