A #1 aluminum wire with a insulation factor of 90 degrees C is rated at 105 amps. Three #1 wires can be installed into an 1 1/2" conduit.

A 60 amp electrical service panel at a 2800 square foot home would be?
If it was preinstalled, it may have been adequate at the time of installation. It depends on the power requirements of the home. If this is a new install, the NEC has a minimum of 100A for service equipment. To be honest, I would install 200A minimum to allow for future expansion.
How much electrical service panel size for a house?
Amps are the amount of power you're using. If you only have one light on then you're maybe drawing 1 or 2 amps. If you have everything in the house on you may be drawing 50 or 60 or more amps.
Can you run an additional breaker panel parallel to the existing one?
It is not in parallel. You put a breaker in existing panel and use that to feed the subpanel. The Amperage of this subfeed breaker should match the rating of the new panel. For example a 100A breaker might be typical. Remember that ground and neutral are only "bonded" at the main panel. Usually a subpanel has a means to separate the neutral and ground in a subpanel. Be careful since everything about doing this is dangerous.Another AnswerYes, you can have two breaker panels in parallel. If you had a 100 amp panel on a 200 amp service (or increase the size of the service, check with your power company on the size of your service, you could add a second 100 amp panel in parallel with the first. You can have up to 6 disconnects per service, but they must be located adjacent to each other or in the same enclosure. So either install the second panel beside the first or a 100 amp disconnect beside the first panel and feed out of the disconnect to the new panel located where you need it.
When did builders start installing 100A service with breakers in new constructions in Minneapolis Minnesota?
I don't know anything about Minneapolis except that it's cold, but anything under 100 Amps is normally inadequate for an average home. Therefore, the service you mention is the bare minimum required for a home of less than 2,000 sf leaving little room for future consumption and the possibility of costs for upgrading to a larger service.
What is the difference between a 60A service and a 100A service and how is the difference recognized?
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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How much does it cost to move an electricity meter?
The meter is typically installed in the main circuit panel of the house. If you want to move it, you can do it as part of a service / panel upgrade. We did this when we moved into our new house - we replaced the 1950s vintage main circuit panel and 100A service with a newer 200A panel and service. It was about a grand, but we didn't actually move the panel from where it was, so it may cost more for what you want.
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.
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.

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

How many circuits can you have with 100A service?
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.
Is it unsafe to have 60A service going into a new electrical box designed for 100A?
Its not recommended because your new main breaker will allow up to 100 amps and your old wire can only safely handle 60amps. If you put a 60amp main breaker in the new box, that would be acceptable. No, it is perfectly safe. Because the box is overrated, there is no problem. If the box is the main panel, and not a subpanel, install a 60A main breaker so you cannot overload your service. If it is a subpanel this 60A breaker should be in the main panel.
Will a 15000 kw transformer power a 2500sqft house?
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
