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.

The amperage that can be used from a service distribution panel is governed by the amperage of the main breaker. If the main breaker is 70 amps then up to a maximum of 70 amps can be taken from the panel before the main breaker trips on an over current fault.

Any combination of branch circuits can come off of this panel as long as there is slots left for breakers to be installed. If you add up all of the breaker amperages in your distribution panel now you will see that the total is well above what your main breaker is rated for.

The main breaker is used for two purposes, one to disconnect the panel from the utility supply source and two to limit the amperage that cam be drawn from the manufactures rated equipment.

If the electrical panel's maximum rated current draw is 70 amps then that is what the manufacturer of the panel found, through UL testing, that that is all it can handle without becoming overheated due to the excessive current draw.

As many as you want, provided they service branch circuits that do not collectively exceed the derated 60A service. For instance, you could have ten 15-A breakers, as long as no more than 6 of them are operating at 80 percent load most of the time.

You can fill the panel to its capacity with whatever breakers are designed to fit. This is because even though you have a 15 or 20 amp circuit you will most likely, in most home applications, never load those circuits near capacity. Each breaker protects the WIRES of that circuit. The 60 amp limit, hopefully in a main breaker, is the maximum allowed amps in actual use at any one time. The 80% load limitation is correct but I'm trying to keep this simple.

Even on a 15 or 20 amp circuit you will often only draw 1 or 2 or 5 or 10 amps, for examples, at any one time. It is the total of all these actual loads that cannot exceed 60 amps.

Can you add a 20 amp breaker to main breaker if total breaker amp is 320 amp Main breaker max is four 150 amp breaker?

Total amps or calculated load has nothing to do with the number of breakers and their sizes. It is more complicated than adding the sum of the breakers, if you do that you will see that they would exceed 200 amps.It is based on square footage for the general receptacle and lighting loads,3000 watts is allowed for small appliances and this is just the beginning.Some experienced electricians have trouble with the calculations.If you are trying to see if you have enough capacity for an addition or some upgraded equipment,and you have breaker space,the chances are you will be O.K. Overloading the service would cause the main to trip.


Can I feed 2 100 amp sub panels from my 200 Amp main service?

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.


How many breakers can be put in a 50 Amp subpanel?

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.


Is it legal to buy a house with a 60 amp service?

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.

Can you put 3-15 amp 2- 20 amp 2- 30 amp and 1-60 amp breakers on a 100 amp service?

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.


How do you install a 50 amp service for a camper?

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


What should you do if your 200A breaker panel is full and you need to add three forty amp two pole singal throw breakers?

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.


Can residential 100 amp service handle a 220 240v single phase 52 amp 12000 watt oven?

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.

How do we do the Layout for 1200 amp service?

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.


Can you put 10-20 amp 3-30 amp and 1-40 amp on a 125 amp service?

This may be cutting it a bit close! I'm assuming that the 30 Amps are for an AC, dryer, and water heater. While the 40 Amp is for a stove. While it's possible these high loads may not be on at the same time, they could be. I would use a 200 Amp service. Otherwise, you may experience lights dimming when these loads come on. An alternative would be to go with a gas stove and/or water heater.
