01
Model split-phase service with two 120 V sources sharing a neutral/ground bus.
02
Use single-pole disconnect switches for 15 A and 20 A branch breakers and two-pole disconnects for the 30 A dryer circuit.
03
Represent the dryer as a 240 V heating element plus a 120 V motor/control load.
Reuse for any residential or light commercial panel wiring diagram where a main breaker feeds multiple branch circuits with mixed 120/240 V loads.
