I = W/E, 18500/400 = amps
500 mcm (or 500kcmil) conductors are used for 400 amp 480v single phase or 3 phase systems. The wire AND THE TERMINALS must be rated for 90o Celsius.
20 amp on a 12 volt system
Amp, Amperes is current. Volt, and any variation, is tension. There's no direct translation between them.
Electrically yes it is safe but the pin configuration will be different.
A 15 amp 125 volt outlet is a household outlet.
There is no 115 volt, 100 amp, or 400 amp switch on the dash of a 2008 Tacoma.

yes
Yes, you can.
A 1000 MCM copper conductor will limit the voltage drop to 3% or less when supplying 150 amps for 400 feet on a 120 volt system.
20 amp on a 12 volt system
A 1-amp adaptor can not be used for equipment that draws more than 1 amp. It is not clear from the question which part of your system is 12 v and which is 20 v.
The maximum amperage capacity of a 400 amp meter main with two 200 amp disconnects is 400 amps.
The maximum amperage capacity of a 400 amp meter base with two 200 amp disconnects is 400 amps.
A
No. If you connect two 12 volt batteries in series(positive to negative) to make 24 volts, you will have 100 amp hours. If you connect two 12 volt batteries in parallel(pos to pos, neg to neg) you will stay at 12 volts but have 200 amp hours
