Sizing circuit breakers for motors falls into a different category. Because of the inrush of current when the motor is in the stopped position, the breaker has to be sized to allow for this. Breakers usually are 250% of the nameplate full load amp rating. The wires that feed the motor are sized to 125% of the full load amps of the motor.

Your electrical dryer keeps popping the circuit breaker?

You may have other devices on the same circuit and adding the current draw of the drier could be overloading the circuit. You may have a short circuit in your dryer. But you may also have a lint build-up in the vent line causing the dryer to overheat. If neither of these are the case, you need to have a professional check it out.


How much current does it take to trip a 30 amp automotive circuit breaker?

In a typical US automobile, a 30 amp fuse will sustain a constant load of 360 watts. Fuses and circuit breakers perform on an "I squared t" rule. For example, a 30 amp fuse will not blow on 31 amps for a very long time. A 20 amp breaker can take anywhere from 10 minutes to two hours to trip on 25 amps. We simply dumb it down so that laymen and technicians need not make mistakes. Power on seven 100 watt light bulbs simultaneously. That means a circuit suddenly provides 50 amps. 50 amps does not trip a 15 amp or 20 amp breaker, again, due to the "I squared t" rule. A 50 amps load only exists for tens of milliseconds. Not long enough. A 30 amp continuous appliance will not trip a 30 amp breaker. But a safety margin means limiting 30 amp appliances to 26 amps or less. Meanwhile, an 18 gauge lamp cord wire typically rated for 10 amps will actually conduct up to 50 amps continuously. Again, that wire is oversized for other safety reasons. And to keep it simple. These concepts apply to fuses vehicles and structures.


What you basically want is will each phase take 26 Amps current for 15HP 3 phase 415VAC motor?

Yes. In a 3-phase motor, all 3 phases have the same current.

Is 26 receptacles wired on one 15 amp breaker up to code or standard practice for residential 26 receptacles include 10 can lights 4 other lights 12 outlets?

NO! You are drastically in excess of electrical code requirement. A 15 amp circuit should not exceed eight total receptacles and/or lighting devices.
