That would depend on the Amp rating of each breaker. If the circuits being run into the panel only require 15 amp breakers then you would have a total of 4. However if you are running larger circuits requiring 30 Amp breakers then you would only have 2 total. So as you can see there are many variables involved in providing an accurate answer to this question.
No, it is not safe to put a 50 amp breaker in a 60 amp panel. Breakers need to be sized to match the panel's capacity to prevent overheating and potential fire hazards. It is important to always use breakers that are compatible with the panel's amperage rating.
No, you cannot add a 20 amp breaker to a main breaker if the total breaker amperage already exceeds the main breaker's capacity. In this case, your main breaker can only support up to four 150 amp breakers, which equals 600 amps, exceeding the 320 amp capacity. You would need to reconfigure the existing breakers to stay within the main breaker's capacity.
DO NOT FOLLOW THE INSTRUCTIONS BELOW!According to this logic, one could chain an infinite number or sub-panels off of a single one hundred amp feed. The second law of thermodynamics prevents this. An hundred amp service is not capable of powering another hundred amp service unless you are trying to move your panel and all of the circuits it feeds as well, without adding another hundred amp load. NEC (National Electrcial Code NFPA Book 72) states that certain loads can be derated but not to this extent.As far as the voltage drop is concerned, you need only worry about this with runs of about two hundred and twenty five feet or more for a 200 Amp Service running 2/0 2/0 4/0 URD direct burial aluminum.What you need is a new 200 Amp service to feed your original 100A panel and another hundred amps to feed your new load.for USA, Canada and countries running a 60 Hertz supply service.Yes you can as long as the feeder to the other 100 amp panel is equal to the ampacity of the breaker. In this case you would need to use a #3 wire rated at 90 degrees C if the distance to the other panel is under 50 feet. If the distance is longer that this a voltage drop calculation would have to be added to increase the wire size. My experience would lead me to believe that you could not install a breaker that was greater to or equal to the rating of the main breaker. To add a sub-panel, you will need to install a breaker that is half or lower than the main breaker.In your case, you have a 100A service; you will need to install a 50A or smaller breaker to service the sub panel.Consult an electrician if in doubt.If you have any doubts about an answer that you get, check the answerer's bio by clicking on their name to check their qualifications.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
As many as you need. Just make sure the main breaker of the subpanel stays below 50 amps (the rating of the subpanel) and the input to the subpanel, whichever is lower.
Wow, never heard of it. Usually 100amp, usually it does not matter what the house has, because it is grandfathered in. But if you ever want to add anything to the service, you might be forced by codes to install a new 100 or 150 amp service, or you might not be allowed to do anything. Call the local power company and ask them if they will upgrade the service to the house for free. Some will. You will need an electrician to put in a new service panel. Could cost a thousand bucks or more depending on the current wiring. A home inspection would also be recommended before buying such an older house.
Yes, the assumption is that when house circuitry is layed out not all appliances will be on at the same time. If for some strange reason they were all loaded up the main breaker would trip. Just keep in mind that the main purpose of all breakers is to protect the wire that is connected to it. Secondally to remove any short circuits that might occur on these wires.
You should not load a 125 amp panel any more than 100 amps.
Yes. Should be done by a qualified electrician with the proper permit.
Hi, I have the same question myself. I spoke to a electrician today he suggested I go with a new* 50 amp service in my camper do away with the old 30 Amp service all together off the new 50 amp service run 30 amp side of the breaker to my airconditioner or my stackable 220 washer/dryer combo and put couple other 15-20 amp breakers in my box for my lighting he suggested that way it also allows play for adding or modifying my breaker box as my needs change its always better to have more than not enough he quoted.... hope this helps a little

Yes, you should have no problems adding this load to a 100 amp service. The NEC recognizes that cooking equipment is rarely loaded to its full potential. You can put this on a 40 amp breaker on # 8 copper wire. The code allows you to treat cooking equipment not over 16000 watts as a 9600 watt load.
First you need to determine if addition of the new breakers will exceed the 200A service under normal operating conditions. If so you will need to go to power company and increase service and put in a larger main panel. If you have the capacity for the extra current you can add a sub-panel and add the breakers there as well as the breakers you will remove from main panel to accommodate the sub-panel breaker. Another way depends on what breakers are in current panel. There are some breakers that can be duplexed in the same space as a single breaker.

HIRE AN ELECTRICAL CONTRACTOR. If you're not an electrician and you're thinking you can put in a 1200 amp service yourself, you can't. If you need to ask how, you shouldn't even be thinking you can. This is a large job which needs to be completed by an electrical contractor. Period.
