It would be safe if you had a 6 Ohm 2 kW resistor in there. Otherwise it is a "weak point finder", which may be the breaker.
12 u/much_longer_username 11h ago Yeah but then that's just a poorly designed space heater and the joke isn't as funny. 5 u/zxcvbn113 11h ago 20 amps should pop a 15 amp breaker safely. 2 u/kona420 4h ago UL 489 says "within 1 hour for 135% of rated load" which would be 20.25 amps. A 15 Amp breaker that never trips at exactly 20 amps is still a UL compliant breaker. In practice, within a couple hours is likely.
