yes 60 times a second

O

yes 60 times a second

So, it comes from the trans on the hot, through the bulb, back to the trans via the neutral and then reverse? So why does it not go to ground, seeing how the neutral is bonded?

Ok smart guys! When electricity comes to your light bulb, does it travels down the hot wire through the bulb then back through the neutral? And then does it reverse because its ac?

Shed some light please

If your eyes good enough, you can actually see it flickering

It's trying to get back to the transformer and it's way easier to take the neutral path back. Electricity is lazy.

You're saying the electricity likes the trans better than the earth? Are you sure? I thought all electricity wanted was to get to the ground.

i was told a long time ago freq. was 25 instead of 60 i bet you could see some

Yes, those electrons are attracted to their source and are always going there, time after time. Because they're going to their source they do not want to flow on the equipment grounding conductors. That's how I understand it anyhow.

And, if everything is reversing and the neutral is carrying current just like the hot did, why oh why is there no ground fault (like there would be if the hot became bonded)t? And there is no voltage read on the neutral????

the neutral is grounded

 

[truelight]

F

the neutral is grounded

But if the hot became grounded it would be a fault. Why can the neutral be bonded and the hot can't? If current is going back and forth through both why do they respond differently when connected to ground?

Because there's 0 potential when the conductor is grounded.

Another word for a HOT conductor is an ungrounded conductor.

Understanding the language is important once you start getting into the NEC.

But you can't make the hot wire (1 of the phase wires) a grounded conductor to make a 0 potential. Why can you do that to the neutral and not a phase conductor?

I thought 25 was the number of frames per second in theatre film...

Because the ungrounded conductor has negatively charged electrons while the grounded conductor has positively charged protons.

 

[Techy]

as long as you only ground one, the electricity doesnt care if its supposed to be 'hot' or 'neutral'. Thats why we call them 'ungrounded'(hot) and 'grounded'(Neutral)

 

[Magnettica]

And the ungrounded conductor - when shorted to ground or EGC - sends massive amounts of fault current which in turn trips the circuit breaker.

Yes, it's trying to get back to the source the fastest way possible. If it traveled through the dirt it would take to long, to much resistance. It doesn't want to get to the ground, but it will if the neutral or path back to the source is taken away since the neutral at the transformer is bonded to earth.

That may be the case for dc but I don't know about ac

I'm pretty sure if you unbonded the neutral and then bonded a phase, you would see fire
