Generator size estimate for amps for a hot water system furnace with 1.0 amp water pump burner controls 8.5 amps ignitor valve 1.0 amp burner motor 10 FLA and 60 LRA furnace breaker on 15 amp circuit?

You add up all of the current draws, 1 + 8.5 + 1 + 10 = 20.5 amps. If you say that all of this load is on a 15 amp circuit then you must get a lot of tripping of the breaker.
If the equipment was on a two pole 15 amp breaker then there would be no problem as the motor current would only be half and the rest of the equipment would operate on the three wire feeding this equipment's neutral.
To over come the starting current of the motor, a factor of 250 % should be used. 10 x 250% = 25 amps. This type of load should be on a breaker of its own.
A generator that will start and run this load should be 35.5 amps x 120 volts = 4260 watts. If like you say its is all on a 15 amp breaker then W = A x V = 15 x 120 = 1800 bare minimum.

What is a generator breaker?
The generator circuit breaker or gcb is a circuit breaker which is connected with the generator . Whenever there is a fault in the generator the circuit breaker trips and disconnects the generator from operation thus it helps the place from a serious accident etc..
How do you define a pole in circuit breaker?
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
What is a switch that opens a cuircut when too much current is flowing?
Where I'm from, it's called a "circuit breaker".A circuit breaker.
Is a circuit breaker a resistor?
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
What is a generator breaker?
The generator circuit breaker or gcb is a circuit breaker which is connected with the generator . Whenever there is a fault in the generator the circuit breaker trips and disconnects the generator from operation thus it helps the place from a serious accident etc..
Is both circuit breaker and circuit gear have same functions?
circuit breaker is break the electrical circuit .circuit gear is generator analyzer
Incase of short circuit will the generator start or not?
Yes the generator engine will start and keep running. The generator has to start before the short circuit is sensed. What happens to the generator section on a short circuit condition is that the generator breaker will trip and disconnect the short circuit on the load. <<>> genarator will not start because of short circuit
How do you define a pole in circuit breaker?
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
Where are all the controls on most circuit breakers?
The only control on a circuit breaker is its on/off/reset lever or button.
What actions to be taken should a main generator circuit breaker stay connected?
I don't understand the question. <<>> If your generator's main breaker does not trip when an overload occurs on the generator's output the breaker's trip setting needs to be looked at. Usually the molded case breaker's face cover can be removed. This will allow you access to the trip settings. Set the overloads to the maximum generator's output. The short circuit setting should be set at 250% of the maximum generator output. If these parameters can not be met on the existing breaker there might be a chance that the breaker has been changed out at some point in time and the wrong breaker was installed at that time. This scenario happens quite frequently on remote operations where the service has to be maintained and the site doesn't have a second back up generator. The site supervisor usually says "just make it work".
Can your 30 amp generator pull a double 20 amp circuit?
When the term "double 20 amp circuit" is used, the presumption is that, it is 20 amps at 240 volts. If your generator has the breaker built in then, yes, you have the capacity to run 240 volt devices from your generator.

Is the circuit where is the is the circuit where is the circuit breaker for the?
The circuit breaker for the headlights is intergrated with the headlight switch.
What will be happening when a generator is running but no output?
Many things are possible. Open circuit or winding. Blown fuse or circuit breaker. Loss of excitation current. Just to name three.
Is there a circuit breaker that controls the tail lightsheadlights and the backlights in the dash of a 1999 olds silhouette?
Is there a circuit breaker that controls the tail lightsheadlights and the backlights in the dash of a 1999 olds silhouette backlights in the dash of a 1999 olds silhouette i have a short in both tail light both burn out ? what can i do to fix it thanks Lloyd
If you have a circuit breaker box containing 650 amps of circuit breakers it is 3 phase 480 volts what size kva generator do you need?
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
