Will a 15 A circuit breaker trip if a 15 ohm toaster is turned on in a circuit that already has a 0.20 hp motor and three 100 W light bulbs and a 600 W electric iron?
A 15 Amp breaker should trip when concurrently you connect to it a 15 Ohm toaster (8A), a 0.2 HP motor (2A), three 100W incandescent lamps (2.05A), and a 600 Watt iron (5A).
