Does a double 50 amp breaker make a 100 amp?
No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.
What is breaker opening time?
The time of opening the breaker depends on the following: 1-The signaling time 2-The relay operating time 3-Trip time 4-The time of breaker to open ,it is about 100 ms
What would cause the main 100 Amp breaker to to break Mine did last night in the home Its a 100 Amp panel?
If you will notice, your individual breakers add up to much more than 100amps. So it is entirely possible not to trip an individual breaker but still draw more than 100amps, which would cause the main to trip. If you haven't had this problem in the past, I wouldn't worry about it unless it happens again. If it does, you need to upgrade your service to more amps. It is entirely possible your main breaker has malfunctioned but that is not easy to test. If it is replaceable, and if you have further problems, you can consider replacing the main breaker to see if that fixes the problem. That is much less expensive than upgrading the service.
If a 100a breaker keeps tripping?
If a 100 amp breaker keeps tripping there is an overload on the system.
If you have a 100-amp breaker box on the pole with a 100-amp breaker going to your house and you get a hot tub that needs a 60-amp GFI breaker would that overload the box?
That's pushing it but it can work. It depends if you have central A/C, electric range, water heater, etc. Those are your amp suckers. You'll need to be mindful when operating the hot tub; not running the dryer, oven, or other large appliances.
How much should you pay for a 100 amp breaker?
probally about 100 dollars

Is it OK to have 250 A of breakers in a 100 A panel?
Yes. Many installations have breaker totals higher that the main breaker of the panel. It is worked on a percentage basis. Not all of the breakers will be on at the same time. In a home, on a 100 amp panel the average load is 50 - 60 amps. The 100 amp main breaker is protecting the 100 amp rated panel board. If the load current goes higher that the panel board is rated at, the main breaker will trip to protect the board.
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).
What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.
What happens if you throw a switched on hair drier into water?
There are a couple things that could happen, worst of all would be harming yourself. If the dryer was plugged into a working GCFI receptacle, then nothing should happen except the little red button on the GFI would trip. They are designed to trip faster than a heart beat. If the dryer is plugged into a regular plug circuit and if the breaker is working, then it will just trip as this will cause a "short" circuit. If the breaker is not working, then most likely there will be lots of sparks because it doesn't trip. Something should trip, even the 100 amp main should go. The only time you would be in trouble is if you are in between the circuit somehow. ie, you are holding onto the tap at the same time and there is copper Plumbing, or you are holding the dryer when you put it in. My recommendation, just don't do that.... Andy The above answer is not entirely accurate. If it is a properly functioning GFI circuit then yes the GFI should trip. The key feature of GFIs is that they detect the difference between the current being supplied and the current returning. If you drop a drier in a bathtub then at least some of the current will be grounded through the plumbing (and you along the way). So the GFI should trip and they trip quickly. However if it is a regular circuit breaker then you do *not* have any guarantee that it will protect you. The water *may* short the drier and cause a large enough current flow to trip the breaker. However it may not. It could have enough resistance to limit the current below 15A or whatever the circuit breaker trips at. In which case it won't trip at all. Regular circuit breakers are there to prevent short circuits from overloading the wiring which would burn your house down. They're *not* there to prevent you from being electrocuted. You, and even a bathtub of water, have resistance which depending on various factors may be enough to avoid overloading a regular circuit breaker.

What is the difference between MCB and MCCB?
MCB (Miniature Circuit Breaker)-rated current not more than 100 A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation. Breakers illustrated above are in this category.MCCB (Molded Case Circuit Breaker)-rated current up to 2500 A. Thermal or thermal-magnetic operation. Trip current may be adjustable in larger ratings.

100 AMP breaker box what should the current read going into it.?
Depends entirely on the load. (ie What's connected to it)
Can you use a 100 instead 20 to change breakers?
To replace breakers in an electrical box it is extremely important the replace the breaker with the same wattage. Do not replace a 100 breaker with a 20 breaker is can cause damage.
If a 100a breaker keeps tripping?
If a 100 amp breaker keeps tripping there is an overload on the system.
