Pulling a full 15A is liable to trip a circuit breaker anyways, it’s extremely rare to need that kind of power from a single outlet. The outlets I use can handle up to 1200W, but the Prusa Mk4 has a 240W power supply, so there’s plenty of power to spare. I don’t imagine even a Bambu would be pulling a full 1200W.

If you’re worried about that, then Prusament PETG V0 is a good option.
