North American split-phase breaker box (23 - Electricity Distribution)

[@tedlahm5740]

Neutral and earth are bonded at the First Point of disconnect? Video said they are bonded at the meter box outside? explanation please.

[@MrPreet17]

Very well explained!

The two black cables coming into the panel - the two *hot* wires. When wired up for 240v one acts as a return (as a neutral does).

[@tedlahm5740]

John : When 240 volts they BOTH act in consort to balance the circuit. No need for neutral in a 240 volte appliance.

[@KevinCoop1]

@@tedlahm5740. In my house, I have (10) 240 volt appliances, and (2) 120/240 volt appliances. So, (10) with no neutral and (2) with neutral. This is of course what you were meaning, right?

[@tedlahm5740]

@@KevinCoop1 Correct. Quite a residential property. Thank you

[@brandonvonbo9708]

both hots act as a return at various times due to alternating current and changes in polarity

So I'm 56 yrs old grew up in Jamaica,when I was 12 my friends dad was a master electrician ,we used to go with him to do residential house wiring for a big housing scheme ,I guess u called that subdivision here in North America ,me and his kids who are very versed in electrical house wiring ,we used to do repair and also steel electricity from the main pole for people that couldn't afford to get their shanty or small houses ran,I became an auto mechanic and a scuba diver,however ,I was always confused with the difference between NEUTRAL and GROUND ...Now I'm in Georgia USA I'm financially defeated by child support,and a friend ,that met is telling me he can get me a job as an electrician,but I don't want to take on that type of responsibility without some basic training on this system used in the usa ,what's your advise

[@johnburns4017]

That panel is _frightening._ Like showing a historical panel from the 1930s.

Branch circuit neutral needs to go back to break if it's gfci (required by NEC nowadays for most circuits)

It’s so different from all I’ve seen elsewhere. Is this typical across North America or there might be differences from one state to the other?

[@user-jt5vm3mi1w]

Typical

[@KevinCoop1]

Although some call it split phase, it is not two phases at 180 degrees from each other. It is “single” phase. If you say “While looking at the system on an oscilloscope, then you can say that. You incorrectly said phase 1 and phase 2 for the hots. They are Line 1 and Line 2. In three phase systems, the connections are called phase A, B, And C. Also, the Earth ground is connected to the “Grounded Conductor” or neutral. It is for lightning dissipation, nothing to do with any of the ground conductors from the panel out to the devices and appliances. The door bell should absolutely not be inside the electrical panel. It is made to be installed on the panel into a knockout. You have lower voltage insulation on the low voltage side conductors mixed within the 600 volt insulated conductors. That’s a NO in NEC.

I hate that it's called single phase. I'd prefer it was called 2 phase and a single 240V - N would be called single phase. I think that's probably the electrician vs engineer debate.

Seriously, I get nervous every time I see you sticking your hands right next to naked live wires

[@johnburns4017]

I use gloves.

It would be so much clearer if he wasn't constantly comparing it to the European method.
