excellent video. I am in same situation with a full panel no more room for 240 circuit for a new dyer, thanks for the explanation needed to do this. I was thinking I would need to put a subpanel to wire the dyer.
So residential 240 systems are called single phase split 240. There is no negative or positive in AC single phase 240. You just get 120 on one split and 120 on the other as long as you use the neutral.
Panel is side way the top row is a code violation now. Just Call grandfather in. On is in a down position on top row it’s supposed to be in up position
Hello. So I'm replacing my really old oven 1995 ish with an old oven 2007 ish. my house was first occupied in 1996 so it was built the year before the 4-wire mandate. So I'm grandfathered in. The replacement oven has both 3 and 4 wire instructions in it. So naturally I have to do 3-wire installation. My question is, can i tap into the junction box and using 12/2 Romex, wire up to the replacement microwave, which needs a standard 15 amp service 120v ? I tested the wiring voltage on all 3 wires and it goes as such. Touching black & Red i get 249v, touching white and red I get 124.5v and touching white and black I get 124.5v. The original stove/microwave unit were both powered by this 3-wire 40amp circuit where the microwave is 120v and oven 240v/120v. It was one big combo unit into this custom home. I realize that new codes call for 4-wire, but my replacement oven supports 3-wire so I'm going to forge ahead in that manner. But i would hate to have to run a new circuit to my replacement microwave. It takes a standard grounded plug. I'm guessing my 3-wire is Hot, Hot, Neutral, which means there really isn't a grounding wire for the Microwave. Is there any other way I could ground that Microwave? Like should I run a wire from the ground of the outlet outside to a grounded post stuck into the ground or something. Any suggestions?
One of many NEC code violations: 1. Horizontal breaker panel is allowed but top row can't be used - breaker on/off must be as a light switch with off down. 2. FMC (flexible metal cable aka BX) clamp - not a typical 2 screw romex clamp. 3, Extension box rather than a closed box. As others mentioned mouse chew hazard, drill or screw penetration from other side of wall, etc. Just plain won't contain an arc. 4. No plaster ring. 5. For 2021 NEC a GFCI is required - depending on state/local adoption/exceptions. Still a safety thing even if not required. 6. No ground pigtail to box - box is not grounded. 7. Ah yes a cover plate would look better and is required - the outlet is for a surface mounted metal box cover as you find on a basement wall, not inside a finished wall.
It's not positive and negative 120V, AC voltage is a sine wave that constantly changes direction from positive to negative and back again. It's actually 120V phase shifted by 180 degrees which gives you a negative peaking 120V and at the same time on the other leg a positive peaking 120V which gives you a potential difference of 240V.
Car Rizzle At least that is what an Oscilloscope will show. Peak voltage for 120 volts rms is 170 volts. Peak voltage for 240 volts rms is 339 volts. These two sine waves happen at exactly the same time and direction. If you use an oscilloscope, because of how it connects, it reads what you are saying. You are going to say that I am wrong. Please explain to me how a phase can shift 180 degrees. There is only one sine wave in the primary winding(single phase). The time, voltage peaks, and and direction of flow must be the same. At least all the electrical laws say they do. Think about it before you tell me how stupid I am. Respectfully, Kevin
@@KevinCoop1 There is only one sine wave but the transformation that is happening on the low-side of the center tapped service transformer that is feeding the electrical panel is what is causing the 180 degree phase shift, and effectively creating 2 sine waves with different phase angle characteristics. The voltage is reduced from the high-side to the low-side of the transformer and then each leg of the output from the service transformer is phase shifted via the inductance of the center tapped winding, and thus the 2 buses of the electrical panel give you 240V when measuring across them. Not calling anyone an idiot just clarifying for anyone who is watching. Respectfully Car rizzle.
Car Rizzle So, with no center tap connection, there is no phase shift, the electrons travel in the same direction and you get 240 volts rms from L1 to L2? As soon as you connect a center tap, everything changes and the electrons start going backward in half the transformer? Where is the additional induction coming from just because of the center tap?
8 gauge copper wire , depends if your house is 3 or 4 wire , there will be either 3 or 4 individual wires in a black cover home depot has what you need
I really appreciate that you took the time to label the chapters in your video! This is a super helpful guide to get more info on the process.
Holy crap, it's amazing how negative people love to be. Great job on wiring your electric stove. Thanks for sharing.
Was it done correctly?
excellent video. I am in same situation with a full panel no more room for 240 circuit for a new dyer, thanks for the explanation needed to do this. I was thinking I would need to put a subpanel to wire the dyer.
Was your addition a success?
Please watch the video for you understanding.
This is what he is going to do for you.
You could use 8-3 with ground for the range if it is close to the breaker box or 6-3 with ground if it is quite a distance from breaker box.
So residential 240 systems are called single phase split 240. There is no negative or positive in AC single phase 240. You just get 120 on one split and 120 on the other as long as you use the neutral.
Thank you so much awesome video

I think he's in Canada. They used to put panels in sideways regularly. Not exactly the same rules we have.
i just bought an electric range and need to change my gas oven and installed it. can you please help me with installation? i'll be very pleased 😀
Great video!!

Does it matter where the red and black wire go in the breaker for stove
Why did you use a box extension and not a box? Not safe, not NEC compliant. Would have looked a little better with a cover plate.
One of many NEC code violations:
1. Horizontal breaker panel is allowed but top row can't be used - breaker on/off must be as a light switch with off down.
2. FMC (flexible metal cable aka BX) clamp - not a typical 2 screw romex clamp.

We can do the same in the UK and get 415V.

So the bus bars 120 on one side and 120 on the others side with neutral in the middle. There is no negative 120 volts in ac circuits.
Mouse arc fault potential with the box extender vs closed box.
Are you talking about the box for the plug
How do you know if your panel can support such a modification
Do you have to use a 4 wire or can you use a 3 wire for a range?
What gauge is the new wire?
It's usually 10/3 they use nowadays, when it come to running wire for electric ranges & dryrers.
@@prestonmcleod1726 No, 8/3 or 6/3 cable for ranges, and 10/3 cable for dryers.
Iz Biz it’s 8/3
@@mr.3phase228 Exactly Right Bro.👍
Great job thank you.
From the Power company to the house, does electricity come in at 120 or 240 volts?
Thanks
120
120 on each leg
Is that 8/3 or 6/3 wire?
what wire should we buy to do this?
8 gauge copper wire , depends if your house is 3 or 4 wire , there will be either 3 or 4 individual wires in a black cover home depot has what you need
00 gauge
What is this type of breaker called at the supply house?
They'll know. This guy doesn't answer back
Tandem breakers
It looks like number 6 wire
Please tell me I heard you wrong, you did not just say you got a 240 amp breaker for your stove
Hopefully not ! But if i did say 240 amps - i must have meant 240 volts . The breakers in this video are rated for 40 amps
He said 2 40 amp breaker,,,, Meaning two individual 40 amp breakers..... Said fast it sounds like 240 amp breaker LOL
Where is your ground???
The Ground that we walk on Everyday, Don't you say....😂🤣
Need a box, an extension box is exposed on the inside and listed to be added an existing box. Sorry, but not to code.
How much was that breaker
About a c note
Lets overload the service.
WTF
You talk to much, just get to the point
Where is your ground?????
At the bottom i saw it
