The formula you are looking for is Watts = Amps x Volts.
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.
One hp is approximately 756 watts.
A small shredder 100-200 watts.
20 Amp * 120 Volts = 2400 Watts 2400 Watt * 80% max use = 1920 Watts planned normal usage for a circuit with a 20 Amp breaker.
The power (in watts) can be calculated using the formula: Power (W) = Voltage (V) * Current (A). In this case, the power required to run the 3 amp well pump on 220 volts is 660 watts (220 V * 3 A = 660 W).
My outlet is listed 100 watt and 400 watt You can rough guess 1 amp per 100 watts. The amp requirement will be listed on the tool.
To wire a 100 amp sub panel from a 200 amp main panel, you will need to install a double-pole breaker in the main panel to supply power to the sub panel. Run appropriate gauge wires from the main panel to the sub panel, ensuring they are properly sized for the amperage. Connect the wires to the corresponding terminals in both panels, following all local electrical codes and regulations. It is recommended to consult a licensed electrician for proper installation.
Yes
Assuming you mean 12 volts, then you cannot run any 78 Amp fans. Unless your fans run at 0.38 volts, there is no way to draw 78 amps from 30 watts.

i just left lowes an they told me to run 100 amp to my building i would need wire size 2-2-2-4 alumninum and run it in conduit the lowes around here does not sell copper wire that size

No you will not even get close to 1600 watts from that amp. If you read the spec for the amp they were putting 16-18 volts into the amp to get the claimed wattage. In your car you will be lucky to get 13.5 volts. You will see maybe 350 watts. A good rule when buying amps is a good amp will run about $1.00 a watt. So a $300 amp will be @ 300 or so watts.
To install a 100 amp sub panel in a residential electrical system, follow these steps: Turn off the main power to the house. Choose a location for the sub panel near the main panel. Install a new circuit breaker in the main panel for the sub panel. Run wires from the main panel to the sub panel location. Connect the wires to the sub panel and main panel. Install the sub panel onto the wall. Connect the circuits from the main panel to the sub panel. Turn on the main power and test the sub panel.
I would use 4 AWG copper to be safe.
