The answer is likely NO. I assume you're talking about a 60 amp subpanel. To upgrade to a 100 amp, the wire size will need to be increased. (replaced with the correct size) This is not a job for amateurs but should be done by a qualified electrician. The typical size wire employed for a 60 amp supply is # 6 awg, whereas the minimum wire size for 100 amp is # 3 awg (which is larger).

∙ 12y agoIn most areas of the United States, insurance companies are requiring an upgrade. Insurance companies will no longer insure homes with 60 amp service so it is impossible to buy or sell the home.
I've seen enough of these 60 amp services to know that they are a hazard. They are so old, so weathered, often so modified by non-professionals that they are simply unsafe. It is not a matter of insurance companies being difficult.
If what you state in this question is accurate this is an illegal installation. A 100 amp service can not have any equipment connected to it less that that of the service size. The 60 amp main panel must be a 100 amp panel to be a legal installation.
If you have 100 amp wire, you can use it for a 60 amp circuit, or for any circuit of 100 amps or less. But if you have a 60 amp circuit, 60 amp wire is thinner and cheaper than 100 amp wire.
Not that I know of. The largest GFCI breaker I have seen is a 60 amp.
Absolutely not. A 60 amp whole house service is totally insufficient to power todays home, especially a 2800 square foot house. The NEC (National Electric Code) requires a minimum of 100 amp electrical service to any single family residence.
In short Yes. However, you must change the main disconnect (breaker) to a 100 amp disconnect. Your local home improvement center may have what you need, or you may have to go to a wholesale dealer to get the main. You will also need to verify that the conductors from the utility and all associated distribution system will accommodate the additional load from 60A to 100A. Always be careful and remember that most home fires are started by electrical failure. Electricity can also cause severe personal injury, including death. If you have any doubt, call an electrical contractor. This type of change to an electrical system should be attempted by only a very experienced homeowner. Your local jurisdiction may also require a permit and inspections be performed. Your local utility may also have additional requirements. SAFETY FIRST and ALWAYS! Hope this helps! Terry

You need to have an electrician install a new electrical service to your home. That would include a new Service entrance cable that attached to the wires that your utility provides you. You will need a new meter and electric panel rated for a 100 amp. The ground system for you electric service also will have to be upgraded for 100 amps.

A 200 amp service panel with a 60 amp sub-panel.
you would use #2 aluminum urd wire for a 100 amp service
AWG # 3 copper.
Get yourself an Quilified Electrician, The wire for the 100 amp fuse is going to be larger than what it would take for a 60 amp fuse so the wires are not going too fit in the 60 amp fuse properly Danger in more ways than one.

As long as the voltages match a 60 amp service will handle a 700 watt microwave. The microwave will only draw A = W/V, A = 700/120 = 5.8 amps.
change 60 to a percent = 6000%60 * 100% = 6000%
