This is a voltage drop question. A voltage and whether it is a single or three phase system must be provided to give an answer.

What size breaker is needed for a 125 hp motor?
It depends on what the amperage of the motor is. The motors amperage depends on the voltage of the motor. The higher the voltage the motor operates on the lower the amperage. So unless the amperage from the motor's nameplate is stated an answer can not be given.Just remember that the feeder capacity to the motor has to be 125% of the motors full load amperage and the breaker protecting the conductors to the motor has to be rated at 250% of the motors FLA. This higher breaker size allows the motor to start without tripping a normal size breaker that is rated for the lower conductor size.
What size breaker would e needed for 10.8 amps?
In standard construction this would require a 15 amp breaker and 14 gauge copper wire.
What is a 30 amp circuit breaker used for?
A 30 amp circuit breaker is needed unless the load is a motor circuit, then it has to be sized to 250 percent of the motors full load amps. For 30A circuit is needed breaker 30*1.25=37.5 --> 40A. If load is lamp or heater, then use breaker of group A or B. If load is motor, then use breaker of groupC or D (very hard start) or special safe breaker for motor - with variable amp setpoint. See related link also. By code you are only allowed 80% of the rating of a breaker. So 30x80%=24amps. 24 amps is the MAX allowed on a 30 amp breaker. You would need a 40amp breaker for a 30 amp circuit. 40x80%=32. So you would want a double pole 40amp breaker.
What size breaker is needed to supply a sub panel that is feeding a range and dryer?
If there is a possibility of both operating simultaneously, then a 100 amp breaker (actually 80 amp if you can find one), and appropriate wiring would be required. Even if they were not expected to operate simultaneously, it would be prudent to wire as if they were.
Adding a 220 line to panel box for a dryer?
A dryer requires a 30 amp receptacle. This will be to receive a four blade dryer plug. The wire needed will be a three copper wire #10 cable set with a bare #14 copper ground wire. The breaker will be a two pole 30 amp breaker.
What is the distance needed around a electrical breaker box?

What size breaker is needed for a 220 v hot water heater?
The wattage of the water tank is needed to size the breaker and the wire to feed the tank.
What size breaker is needed for a 1100 watt microwave?
A minimum of 15-amp breaker is "needed", but a 20-amp is often required by electrical code for that situation.
What size breaker is needed for a 125 hp motor?

What size circuit breaker is needed for a 300 watt bulb?
A 15 amp circuit breaker will handle this situation very well. The smallest home breaker is rated at 15 amp.
How far can power line be from house to pole without transformer?
It depends on the total load spread along the line and the voltage drop at full load at the end of the line. Generally up to 3 % voltage drop is considered ok. Anything beyond you need another transformer center.
How big of a circuit breaker needed for two 1500 watt that are 240 volts?
A 30 amp breaker wired with AWG #10 wire.
Can you run a 40 amp breaker 65'?
This question is at cross purposes. A breaker is used to protect the conductor that is connected to it. With a distance being added into the question it turns it into a voltage drop question. Depending on what the amperage of the connected load is, a 40 amp breaker might protect the conductor. A voltage needs to be added to the question. Re-phase the question to include a voltage, and load current. For example, What size wire is needed at (voltage here) with a load amperage of (amperage here) over a distance of (distance here). Once the wire size is established then a breaker is chosen. It also helps to know what the load is, eg. motor, sub panel, transformer, because additional calculations need to be made.
What size breaker would e needed for 10.8 amps?
In standard construction this would require a 15 amp breaker and 14 gauge copper wire.
What size breaker does it take to run a outdoor well?
Normally AWG #10 wire on a 30 amp breaker but it really depends on the size of the pump. The pump manufacture will specify the size wire and size breaker needed.
What was the only ticket needed to ride the underground railroad?
The desire to work
How many Breakers needed to wire an electric furnace?
The electric furnace operates on 240 volts so a two pole breaker is needed.
