The difference is the difference in the size of service entrance conductor and maximum ampacity of the service equipment [panel].
The panel will be labeled and the main breaker, if there is one, will say 100 on the operating handle.
It is unlikely you will find a sixty amp service unless it has fuses [probably with pull-outs] and cloth service cable [it will be very old]. Many of these old fuse services may be 100 amps.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
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-energized.

Yes. Five 20 amp breakers would be 100 amps. It doesn't work that way. The load placed on this box at any given time cannot exceed 100 amps. You can put as many breakers as it will hold.
The minimum size grounding conductor for a 100 amp service is a #8 bare copper wire.
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.
No because 100a-35 is an algebraic expression containing two terms.
That depends entirely on your service. Look at the meterbase to your house; if the shutoff says "100A", you have 100 Amp service. If the shutoff says "125A" you have 125 Amp service... you get the idea.
Power = Current x Voltage = 100A x 220V = 22000W
NEC 310.16 #3 Thhn Copper
It is [ 100A ] percent.
In my experience it is best to upgrade to an 200 amp service. The cost difference is minimal and is a selling point for the future. This includes replacing the service cable and Meter Box.
A 100 amp residential panel requires that you use AWG # 3 service entrance wire.
You would have to ensure that the service entrance cable can support 100A. Depending where you are located, you should inquire of your electricity provider if you are equipped for 100A. It may also require a meter change out.
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.
I'm assuming you mean 100 amp service, not circuit breaker? The NEC code states the minimum service is 100A. Depending on your definition of "small", this would be sufficient. It all depends on your large loads too (Electric water heater, Air conditioner, electric range, etc). These appliances can pull some large amperage.
#3 copper wire if it is very close by.
It is 100A hundredths.
I just removed a ALT 100A fuse in my buddy's Toyota Corolla from 93'. I had to disasemble the hole fusebox in the engineroom, to take the fuses out from beneath it. They are boltet on, (search google: "ALT 100A" first article). Hope this was helpfull. Rasmus DK.
The Electric Company - 1971 100A 5-100 was released on: USA: 5 March 1976
Miniature circuit breaker is up to range of 100 A and smaller in current capacity in compared to MCCB. In MCCB the current carrying capacity less than 100A and other difference between MCB and MCCB is its making one is not moulded and second one is moulded
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.
A 15000 KW transformer will power a small city! One KW is one thousand watts, so 15000 KW is 15,000,000 watts. The average 2500 ft2 house in the US uses somewhere between 24000 and 48000 watts maximum (thats a 100A or 200A service). Did you perhaps mean 15000 watts? That would correspond to a 60A service, which is pretty small. If you have gas appliances (stove, furnace, water heater, clothes dryer) and no big electrical appliances, such as an air conditioner, then maybe a 60A service would do. Most jurisdictions require a minimum 100A service these days except in unusual situations, such as mobile homes and such. A house that size should have a 200A 42 circuit panel. This relates to a 50Kva transformer
It depends on a number of factors. The size of the service wires, the meter rating, the main breaker panel rating, etc. will have to be rated for the amperage you want to go up to.
