Terry, does the regulation allow to to drill a thru hole in the main outdoor breaker box to my garage on the other side of the wall? I need to install Wi-Fi antenna for the monitoring system. Breaker box acts as a Faraday cage and I really don't want to drill holes outside panel leaving antenna exposed. So, I'm going to drill a hole thru metal case straight to my garage, just wanna check if I'm not violating any codes.

[@KitchenerLeslie2]

Arthur Vin you’re not supposed to add any holes to a panel or meter pan.

[@arthurvin2937]

@@KitchenerLeslie2 I found a better option! The main breaker panel has a big distribution hole already which opens inside the wall in between the panel and garage and where all the wires from the breakers go. I will punch a hole in the drywall from inside garage and route current transformer wires from the panel inside to garage where Ill install my monitoring system. This way I'll eliminate Wi-fi signal issue as well as keep breaker box clean of additional equipment. How does that sound?

The explanation of the electrical system is great! The only thing is putting your hands and fingers on the panels and their components. Thats is making me nervous. Do-it-yourselves may do the same thing not knowing that the boxes are energized. It would be better to use a wood pointer or a pen-pointer. Thanks for your time and effort to upload your Vds.

[@chrismitchell6478]

The panel you are showing is a sub panel, you have it wired as a main panel. The main panel isn't defined as the first breaker panel inside your house. A main panel (or service entrance panel) is simply a panelboard that contains the main service disconnect for a property. That panel is located outside your house as shown in this video.

[@theinternetelectrician]

Chris Mitchell thanks, and you are correct, only you missed that I explain that very point and the inside panel is set up to demonstrate how the connections are made c/w bonding the neutral in a main panel.

[@chrismitchell6478]

@@theinternetelectrician I did catch that but I though it necessary to point out that the panel is wired wrong as it is, it is demonstrating a main panel however it isn't a main panel. Do you follow what I'm getting at. Also it's not even just that the bonding screw was in for this example, the neutral bus bar has ground wires connected to it, which in the main panel is okay, but as this panel is not actually a main panel it is wired wrong and is in need of a rewire, at least a partial one.

Hi Terry. Ben here. Just stumbled across this video. From an electrical inspector's point of view, it looks like you know what you're talking about. ;)

[@andream.3759]

Thank you, this is informative and simple. I do hope that you were recording and touching the panel while it was disconnected from the power source. You should always include safety, such as, don't remove the panel cover unless the power is disconnected.

[@theinternetelectrician]

Good input, but I do always stress the importance of safety, and de-energizing before working on electrical circuits. At the 2:55 mark, I explain that this is a panel that I use for demonstration purposes only.

[@jaredhouston4223]

I first thought you made a mistake about the panel inside the house. I thought it was a sub panel, but I re-watched the video and you said those lines where being fed from the meter directly to it, so yes this would be a main panel. If it where a sub panel the ground and neutral would have to be separate, which you also touched on. Good video.

[@theinternetelectrician]

Thanks Jared. Yes, I used my panel in my demonstration wall just to control the conditions and environment for shooting the video.

[@homeassistantiptv8068]

[@whith5184]

sorry, i feel a little confused about the terminology. you've called the panel in your video the Main panel. is this not the subpanel? since the combination panel outside is the Main as the meter feeds it directly and has the main shut off there? i feel confused because subpanels don't have the neutrals and grounds connected like shown in your video. I'm a new student studying Home Inspection with zero experience in electrical, so i'm trying to get supplementary info from youtube videos. I'm also from Canada, so I'm wondering if terminology might be different? any help would be very much appreciated.

[@theinternetelectrician]

As I explained in the video, I show you the main panel at the beginning, but I move inside for a more controlled studio atmosphere and yes, that panel is technically a sub-panel, and is connected as such, but for the video I have made it to appear to be the main panel just for the demonstration, and I indicate that in the video script.

I really want to learn about this. Thank you for taking the time to share your knowledge and show what you are talking about.

[@RTD1947]

Terry, what is the difference between a ground and a neutral. Why both?

[@theinternetelectrician]

Neutral is the intended path for current flow (the ungrounded conductor) The ground is the fault path for current flow and should never have conduct current except in a fault condition (the grounded conductor). It reduces the risk of you becoming the path for the fault current.

[@sonyyoung1036]

Can you explain why neutral and ground are bonded? It will create 2 paths for electricity to return on a circuit. What am I missing? Thanks

[@theinternetelectrician]

This is a complex topic and sometimes hard to understand for sure. But the short answer is that the "grounding" or earthed conductor is the fault current path. The neutral, or "grounded" conductor is the intended path for current flow. Think of it as a floor drain in the basement of a house. The water you use in the home is intended to be captured by the sewer pipes and routed to a system that takes it back to be treated, and then returned to the water cycle. But if something goes wrong and a pipe bursts, either on the pressurized supply side of the water lines (hot wires), or on the sewer pipe somewhere (the neutral lines), that floor drain (ground wire) is there to take that water away to mitigate the damage until the problem is fixed! *(Hey, I've never used this analogy before, but it's brilliant if I do say so myself :-)

[@sonyyoung1036]

@@theinternetelectrician Excellent analogy! In the case of bonding neutral and ground, using that analogy, we are connecting the sewer drain and floor drain so when water is flowing down the sewer there will be a point where the water can choose either the sewer or floor drain. This is what I don't understand. Why we would give water (electricity) a choice of paths to take even when there is no pipe burst we will undoubtedly get some water to flow down the floor drain when the path should be all down the sewer drain.

[@theinternetelectrician]

@@sonyyoung1036 But the floor drain is only there in case of emergency. It should never be flowing that way unless there is a problem, and if that happens if we go back to electricity, the path for current flow is so large that the breaker trips, stopping the flow. Then we correct the problem. With the plumbing analogy, you would have to have some kind of circuit breaker (which they do make now) that recognizes un-controlled flow, and shuts off the main! If you didn't have that alternative path, you have a problem, you flood the house! All about mitigating risk to property and people.

[@sonyyoung1036]

@@theinternetelectrician I think you are saying that, at the main panel, a circuit will return via neutral because it is easier than taking the path via ground. Thanks for the responses!

[@valb4184]

Thanks Terry. Where is the switch you turn off in case of an electrical fire?

[@theinternetelectrician]

On the video, at the 2:20 mark, the large breaker alone at the top of the panel is the main breaker in this particular distribution system. That is what you would shut off in the event of and electrical fire. This would deenergize all circuits in the home.

[@valb4184]

@@theinternetelectrician THANKS!

[@ArielVolovik]

The electrical panel only has 2 hot wires, 1 neutral, and 1 ground? Aren't houses given 3 phase AC? How is it that there's only 2 hot wires?

[@theinternetelectrician]

Yes, almost everywhere on the North American grid, single family dwellings are serviced with single-phase, 120/240V transformers. Two hots, a neutral, and a grounding / earthing system. In multi-family units like apartments or condominiums, they will bring in 3-phase at a higher voltage, then transform down to 120/208V and still only feed each unit with 2 hot conductors and just divide the load amongst the 3 hot conductors to the individual units. Thanks for watching!

[@motodrummer]

so wjhen are amps added? I assume amps are added by means of resistance correct? does the transformer have resistance or the home circuit panel.. Sorry if dumb question in my 2nd week of 101

[@jordangause6559]

Is the neutral conductor hot and or cold? (Can it be both?) Or is it simply called neutral.

[@stevenreyes3680]

I replaced our clothes dryer because the heat stopped working. New dryer wasn’t getting warm. THEN noticed the breaker was tripped. Replaced breaker. And IT trips. This all happened after the water heater had sprung a leak, just on the other side of the wall. I’ve decided the outlet is to blame do to moisture, causing ground fault or whatever, Is this possible ?

[@jolyonwelsh9834]

I don't install any breaker box with a back fed main breaker. It can lead to a disaster. I only use panels in which the main breaker is solidly bolted onto the busses such as the Siemens and square D panels. Over time the tension of the clips in the main breaker loosens causing a point of resistance. Thus they heat up and burn the bus tabs onto which the main breaker is plugged.

[@theinternetelectrician]

Yes, I’ve seen some fails like that as well, but far more due to poorly done terminations to the lugs.

Is there a way to get electricity directly from the telephone pole or the wire that heads to your panel without it going through the meter

[@Ryan-hr9hw]

Climb up to your weather head and connect some wires. I'd reccomend having a professional do the work.

[@grandpa6535]

Why would you bond your ground & Neutral in a sub panel? The bonding is to occur at the first means of disconnect. Additionally, that trunk cable fed into the sub panel should be coming from the exterior distribution panel (where the bonding is to occur.

[@theinternetelectrician]

You are correct. You don't bond in the sub panel. I explain that in the video that this panel is on my demonstration wall, and that it is only to demonstrate how you do bond if it was a main panel.

[@joeclark8029]

Thank you for the great video. I thought higher the voltage higher the amps? Can you explain please.. You said higher the voltage lower amps? Im trying to learn.. Thanks again

[@theinternetelectrician]

Joe Clark yes, if the load is constant the relationship is inversely proportional. So if you were using 100 amps at 240v, a high voltage transmission line would carry 1A at 24000 volts to the transformer (just as an example, not actual values used).

[@joeclark8029]

Terry Peterman thank u

[@waqeebsayeed3294]

thanks for wonderful video! but i had a question, what is the difference between a neutral and a ground wire?

[@josephs9341]

Neutral wire provides the return path for the voltage back to the panel. The ground wire is connected to earth to provide a path to ground in case of a fault. Ground wire has lower resistance so it trips out the circuit breaker by allowing more current to flow through it.

[@GmGarlo]

i tested my breaker in the panel with a multimeter and got 121 volts then i tested the outlet and got121 volts but when i put a load on it the outlet stopped working but the breaker did not trip , whats your thought on that?

[@svartorivigt5016]

GmGarlo Not sure if you have managed to fix it yet. I'm educating to become a electrican in Sweden, so the Components are a bit diffreant from what I have in my country but the basics are still the same. Have you checked that the outlet still gets it's 121 volts when you add the load? Otherwise you could observe what the breaker does when you add the load to the outlet.

[@theinternetelectrician]

@@paintingwithtastefromcanva7165 It's very likely a problem with the main breaker, in the meter socket, or the feed from the supply authority. Start with the main breaker. Push it fully to the off position, then back on. If that doesn't do it you will have to call an electrician to determine if it's the main breaker that has failed on one leg, or if the feed to the main breaker is the issue. If it's a failed main breaker in your main panel, then it's your issue and you pay to repair. The electrician will need the power company to pull the meter to do this. You can also call the power company to come check if it is a problem on their connections as they don't charge for that.They will also check the meter base to see if that's where the issue is.

Ive seen you canadiens use the service loops before boxes. But is that legal in the u.s.? Nec says 8 or12" from the box right? Doesn't that count wire length?

[@mikeed90]

[@mikeed90]

sry my english is bad, and im not electrical base student.

[@theinternetelectrician]

Zaid, no, the transformer does not convert to DC. It stays as AC, just lowers the voltage. When we change AC to DC, that is called a converter or rectifier. When we change DC to AC, that is an inverter.

[@mikeed90]

Terry Peterman thx man for replying!!! so in our house is AC? but i thought AC is vary(meaning positive, then goes to 0 then goes to negative). If it is AC how come my light bulb in my house acting as if it receive DC?

[@theinternetelectrician]

The alternating current happens so fast that the human eye is incapable of seeing the fluctuations. We're talking about 50 (EU) or 60 (Americas) cycles per second where a voltage of 120Vac goes from 0 to 170v + back to 0v, and then to 170v - in a sinusoidal wave (sine wave) The RMS value is 120V. It's a bit complicated, and that's why electricians have to spend time in tech school learning this "behind the scenes" information that really proves to be quite useless in the real world!

Terry - I built my own dual-axis solar tracker energy system, utilizing a transfer switch to my main service panel (proper city permits and installation city approved). Sold that house & system, bought another. I want to avoid the complexity of a transfer switch and its complex wiring by going directly to the service panel this time. I will purchase and install an interlock switch that will lock out the 200A main when needed. I will insert a 240vac CB into the top slot of L1 and energize it with a source (generator, solar, battery bank, pure sine wave inverters - etc). My question is: will that ONE 240vac CB energize both L1 and L2? It seems it will, given that it touches both.If not, can I accomplish what I want by putting an additional 240vac CB at the top of L2 and energize both of those top CBs with my energy source (obviously, within the power output capability of that energy source). The point to this exercise is to provide energy to all CBs below the one or two I have energized. I do NOT intend to have them ALL turned on at the same time and will select only those needed for the function at hand...always within the ranges of my energy source(s).

Thank you for the video but you didn’t explain the very basics of why are there four wires, red, black, white and green and the function of each. It would be nice to know.

[@12StringHWY]

Thanks Aye. This was simply explained. I'll send you a 12 of Kokanee Terry. I know you won't turn it down Aye.

In 2017, it would really be good if you recorded your presentation in 1080p, so that the picture is not blurry. Thanks.

[@juliancontreras7053]

thank you for this

[@danielmarone5757]

That looked like a main panel outside, so the panel inside should be a sub panel were all your neutrals and grounds are separated... What am I missing here?

[@ackmino]

You are correct. Everything after the first disconnect should have isolated ground and neutral.

[@FireandFrostHVAC]

Glad I found this channel, thank you.

[@brotherdekaka]

Thank you,thank you men I have been searching for a good information like to this

[@naeembagwan9541]

Thanks so much I am from India it's little different here thanks once again

At the big store where I work we use floor scrubbing machines-got 4 of them with onboard chargers. Each machine has 4 12v car batteries. Two 120v wall outlets have caught fire in the charging area-burns on the wall and melting the plastic and wiring. Any number of flammable things nearby. From what I've found out it was because two machines were plugged into the same outlet. The electrician came and replaced the two outlets. Now store management has put up a sign saying 'only one machine can be plugged into an outlet. I've had some electrical training and work experience. I don't understand this. How can you overload these outlets without tripping a breaker? How can this condition even exist legally? Shouldn't each outlet have it's own circuit to prevent this? These are common duplex 120v outlets but they must not be separated with separate circuits. Now they just put tape over one of the duplex outlets.

[@KitchenerLeslie2]

deric smith certain breakers out there don’t trip as they should FPE is one. We’ve replaced panels at entire condo complexes because of this. Also you’re supposed to cycle breakers and mains often to keep them moving freely. You could have a faulty breaker.

[@KitchenerLeslie2]

Or they could be over fused. Some knucklehead could have put a larger breaker on the line because the circuit used to trip when you guys were overloading the circuit.

[@mikerevendale4810]

That was the result of an improper and dangerous electrical setup. The wiring is likely only 14 gauge which can only handle 120 volts with a 15 amp circuit breaker. It's also likely that it's on a circuit with a 20, or even 30, amp breaker. And you've witnessed the results. The only other possibility is that they're using common receptacles that are rated for 15 amps that are on a 20 amp circuit that has 12 gauge wire. If that were the case the receptacles need to be upgraded to the heavy-duty 20 amp versions; that is, unless the circuit has 14 gauge wire which only rates to 15 amps. Regardless, it's not rocket science and it's clear whoever is in charge of the electrical service is ignoring the basics of the field.

[@dieseldan3545]

I want to install a subpanel my main panel is 125 amp 20 space. The new subpanel comes with 100 amp main breaker. What should all the main breakers be?All 3 main breakers 100amp?

[@dieseldan3545]

Never mind I just paid an electrician to answer my question more quickly.Asknow.com for$9

Seems to be what I was looking for, but no audio for some reason

[@modernagricultural9257]

Beautiful

[@firstmaje2271]

Is this means we can use up to 200ax220v=44kw?

[@firstmaje2271]

What is the maximum I can get from the transformer?

[@apluselectrical]

Nice video sir

[@birendrathapa7036]

thankyou its helpfull for me

[@colincox1whichnet]

Thank you for taking the time to make these videos I thought I would start the vids at the beginning and I am glad I did. great to learn about ground/earth and neutral bond together in upper distribution panel and separate lower half!!. why is that is the question?

[@KitchenerLeslie2]

colincox1whichnet if you still care: my guess is so if you get an open neutral situation at least the bare grounds won’t become hot.
