You should not load a 125 amp panel any more than 100 amps.
Depends on the size of the service. 100 amp service will require 3 gauge, 150 amp service will require 1/0 gauge, and 200 amp service will require 3/0 gauge.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.

Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
A 100 amp service will supply your electrical current needs UP TO 100 amps.When doing load calculations on a 100 amp panel it can only be loaded up to 80 amps.

In how many amps of current before blowing out. 2 amp 5 amp 10 amp 15 amp etc.
The underhood fuse box. its either an 80 amp or 100 amp fues
You can install a 100 amp sub panel off a 60 amp main panel fed by 100 amp service. This allows for the sub panel to be adequately powered with headroom for future circuits or expansions. It is important to ensure the wire size from the main panel to the sub panel is sufficient to handle the load.
No, each size service needs its own meter base.
Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor. From the 200 amp feeder panel you will require a 100 amp two pole breaker for each of the two 100 amp services. Keep in mind that if you run the 100 amp services close to maximum this will take away the capacity of the 200 amp service for other branch circuits coming off of it. Also keep in mind that if the panels are located, not in the same building as the 200 amp service that the 100 amp panels will be treated as separate services and will have to be constructed like a 100 amp service. This includes ground rods. Also the bonding screw will have to be removed that connects the neutral buss to the panel enclosure.
Depends on the size of the service. 100 amp service will require 3 gauge, 150 amp service will require 1/0 gauge, and 200 amp service will require 3/0 gauge.

The 2 - 60 amp maxi fuses in the power distribution box in the engine compartment are for the passenger compartment fuse panel
Yes you can as long as the sensing coils of the transfer switch are the same as the 100 amp service. The transfer switch has to be able to tell when the voltage is back from the utility side of the switch when the power is restored.
