I just added a circuit to my breaker box and it got me thinking about how the wiring all works. The neutral and ground both go to the bad bar in the circuit box, if they’re both in the same place then why can’t that just be wired inside the outlet and a single wire runs the length instead of two?

To complete a circuit you need live and neutral, basically it’s not enough to pump electricity into something, it also has to have a way to escape to actually flow and deliver power. Ground is there to make sure that
A) IF current goes anywhere BUT from live to neutral, it has a better way to go to ground than through you
B) If you have any current going from live to ground you know that somewhere there are amps leaking out of a device so you have a special breaker that sensitively measures the amps through ground and if there are any the breaker has to trip within a very short time to, again, don’t allow live to deliver power through you if you touch the leak.
Ground is there to save you life. Neutral is there to power your stuff.
