This is a very simplistic example of the electrical system in US homes. Top left of the schematic is the step-down transformer. Coil secondary represents the service to the home. The top circuit is Line 1, center is neutral, and bottom is Line 2. The first two switches from the transformer would represent the main circuit breaker. I did not include actual circuit breakers, just switches.
Where you see microOhm resistors, I was just trying to represent the breaker panel's neutral bus so the wiring looks cleaner. Consider them conductors.
I wired ammeters on each branch so you can see behavior of various circuits and the effects of different components and switches.
The third branch down from the mains is using L1 and L2 representing a 240V double breaker. I tried my best to represent a clothes dryer on this circuit. I used a relay to behave as a 120V motor that closes a centrifugal switch to operate the dryer's 240V heater. The "bulb" in that component is my way of trying to show the heater is on. Open the door and the dryer stops but the light comes on.
The fourth branch taps L1 and neutral. This was my feeble attempt at a microwave oven. Make sure you plug it in!
Branch five is a chandelier. Turn it on from either side of the room! LED lighting on that branch as well.
The lower branch I am attempting an AC to DC 5V charger for devices.
Electricians, take it easy on me, I'm aware I provided no earth ground on the branch circuits and things are likely not wired to code. I am also not well-versed in electronics. I am trying to learn and am open to suggestions. Ideally, I would like to build grounded cases around certain components to show how faults behave, however I have no actual circuit breakers. Main switches are on. All else, you must provide power. Playback timebase should be set to max. Enjoy!
