distro 300 amps main breaker

edison

L6-30

my questions are :

(1) is each individual circuit at 20 amps?

for example pic 1 : circuit #1 has top and bottom . are both top and bottom

or example pic 2: are both top and bottom

(2)Total amperage is 300 amps?

[how to make these calculations?

L6-30 (30x3 =90 amps)

L21-30 (30x3= 90 amps)

**together**at 20 amps?or example pic 2: are both top and bottom

**individually**at 20 amps? or is top and bottom both divided**equally**( 10 amps each)?(2)Total amperage is 300 amps?
