As many as you want without exceeding the 100amps. You could have 100 circuits if all you have is a single 100watt light on each circuit.

Did one leg of your 1950's 100A main breaker fry because it was overloaded by too many dedicated circuits?

It is possible that one leg of the 100A main breaker may have fried due to being overloaded by too many dedicated circuits in the 1950s setup. If the circuits were drawing more current than the breaker could handle, it could have caused overheating and damage to that leg of the breaker.


How many circuits can you have off a 200 amp service?

The number of circuits you can have on a 200 amp service depends on the load of each circuit. As a general rule of thumb, you can have up to 40-50 circuits on a 200 amp service panel, but this can vary based on the specific requirements of your electrical system and local codes. It's important to consult with a licensed electrician to determine the appropriate number of circuits for your installation.


How do you upgrade the service from a 120V 100A circuit breaker to 240V 30A for appliances like ovens and dryers?

Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.


What is the difference between a 60A service and a 100A service and how is the difference recognized?

The main difference between a 60A service and a 100A service is the maximum amount of current they can handle. A 60A service can handle up to 60 amps of current, while a 100A service can handle up to 100 amps of current. The difference can be recognized by looking at the size of the main breaker or fuse in the electrical panel.


Considering 100A 240V service has 2 poles at 100A each is the total usable power actually 200A at 120V?

No, amperage is not additive, but a constant. Think of power as water, its always the same temperature, hot (amps). The pressure is variable (volts). The true answer is undoubtedly more complex, but you get the point. If you need to draw 200 amps you would actually need a 400 amp service because code states you cannot have more than an 80% load on a breaker That's an interesting question and I had to run the theory through my brain a few times to confirm my answer. The answer is if you have a 100A 240V service, you could draw what appears to be 200A from that panel at 120V. If you install 100A 120V single pole breakers on each side of the panel (in reality this would be many breakers but let's keep it simple) then both breakers will operate just fine, giving the appearance of 200A. In reality, however, one breaker actually feeds through to the other breaker. The neutral only carries the unbalanced load so in this hypothetical situation the neutral at the panel carries 0A. So the answer to the question is...if you install ONLY 120v single pole breakers, you can run up to 200A on those circuits (or 80% of that as we have discussed.) But you are only running 100A on each leg of the service conductors and breaker.

Is 100a - 35 a monomial?

No because 100a-35 is an algebraic expression containing two terms.


How many 20 amp circuits can you run on a 50 amp service?

In the United States, there isn't a hard limit on how many 20 amp circuits that can be run on a 50 amp supply. This is because in most cases, especially in homes, we don't load most circuits with more than an amp or 2, even when they are protected by a 20 amp breaker. From a practical perspective you probably have a limited number of slots for breakers in your service or supply panel.

How many single phase can you run on a 100amp 3 phase?

You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
