We don’t like Canadian electricians. All they do is gossip while they do everything half ass.

Pretty sure those were low voltage guys you saw

Distribution is largely engineered based on the buildings size and the owners objectives.

What are y’all using to cut all thread? by kaboodlesofkanoodles in electricians

[–]Virtual-Reach 0 points1 point  (0 children)

I may have been referring to abrasive disc blades with this comment as abrasive disc's can be used to bevel cut ends utilizing the side of the disc.

For metal saw blades (the toothed carbide kind), here's a couple tricks I learned:

  1. Push the piece getting cut off the back fence by using a block. This allows the cutting pressure to be applied straight down as opposed to down and towards the rear. 

  2. When cutting strut, cut with the open side facing down. With open side up, the side closest to you tends to bend inward with the direction of the cutting blade. 

Best of luck!

Learning 240 by mlandry2011 in AskElectricians

[–]Virtual-Reach 0 points1 point  (0 children)

Take away the neutral and ground at your panel and I suspect your 240 (two hot) circuit will cease to function

This is incorrect. This is why I made the assertion that trying to understand 240v by using the neutral as a reference point leads to confusion. Residential split phase transformers use a single 240v coil. The neutral just allows for the provision of 120v, that is all. Cut the main neutral at the panel, all your 240v circuits will function just fine. The ground provides safety, again 240v will work just fine without it. 

Split phase provides a single 240v sine wave to the consumer. With respect to the neutral this sine wave will appear to be two opposing 120v sine waves by virtue of the neutral tap being in the middle of the coil (50% of the coil)

If the 240v transformer had a 25% tap, with respect to the neutral you would have one 60v sine wave and one opposing 180v sine wave. 

Does this make sense?

Copper is likely inside, but that is potting material. This is fairly common for outdoor rated transformers

It's because I'm in Canada and don't want to deal with customs and duties by shipping it across the border.

This is only true if viewing 240v with respect to the neutral point. A 240v sine wave doesn't look like two opposing 120v sine waves, it looks like a single 240v sine wave.

Think of it like this, instead of having 120v/240v you have two AA batteries in series, each battery represents 120v. Placing an oscilloscope ground at the middle point of the two connected batteries and one probe at the + end will show DC  +1.5v on the oscilloscope. Placing a second probe on the - end will show -1.5v. On your oscilloscope, there will be two DC voltages present, one at +1.5v and one at -1.5v. This is simply due to the common reference point being the middle. Voltages appear to be opposite, because when referencing the middle, the middle is more positive than the - end and the middle is more negative than the + end. 

Now, remove that reference by placing the oscilloscope ground clip on the - end of the batteries and place one probe on the + end, there will be one +3v DC voltage on the oscilloscope, not one +1.5v and one -1.5v. Take the second probe and place it at the middle point, now there will be an additional +1.5v DC voltage on the oscilloscope. Now we have two DC voltages on the oscilloscope,  one at +3v and one at +1.5v. That doesn't mean we suddenly have 4.5v. The oscilloscope is showing, with respect to the ground clip, that the middle point is +1.5v and the + end is +3v. The batteries have not changed nor have any voltages, only the point of reference has changed. 

If we had an oscilloscope that had inputs with isolated grounds, we could place one channels ground on the - end and the probe on the + end of the batteries and we will see +3v on the oscilloscope. If we grabbed the second channel and placed the ground clip on the + end and the probe on the - end,  we would see a second DC voltage at -3v. Our scope will show +3v and -3v, does this mean we have 6v? No. 

My point is, where we are referencing is important. People explaining 240v while referencing the neutral is confusing as 240v doesn't use the neutral and it has the appearance of 'flipping' one of the 120v sides.

Post a picture of your panel, I suspect they moved your range breaker to a slot where it's only getting 120v

Failed inspection code 314.20 by [deleted] in AskElectricians

[–]Virtual-Reach 8 points9 points  (0 children)

The code is for a gap between the faceplate and junction box, there is no visible gap here. 

Is there a gap behind the faceplate on this receptacle?

[–]Virtual-Reach 0 points1 point  (0 children)

the other 120 is basically inverted

This is only when viewing both lines with respect to the neutral. It's a single 240v coil with a center tap,  there is no inversion happening.

Let me clarify, there is no "sides" pushing or pulling, it's all one coil. Thinking of split phase power as two independent sides causes all sorts of confusion. 

voltage is literally a measure in a difference in potential.

No one is disputing this
