I already told you - a center tapped transformer. That is tough for me to explain further without pictures etc. I don't do well with text.SO explain how they get 240v with 1 phase and a neutral?

:goodpost:.........:animlol: :animlol:After 40 years in the electric utility business , I read a post like that and think " what the **** " ?
Already explained. Magic (or Satan)SO explain how they get 240v with 1 phase and a neutral?
My buddy from Australia (where they have 220-to-ground, single-wire system) - had an irrigation pump go down one night.<snip>
Not ragging on anyone there are good people out there. Please if in doubt call a expert. WE don't do brain surgery just electric work. Please be safe.
Not really "wonky", it would be 208V.Incorrect, it takes one phase and then the transformer is center tapped to give you the neutral. If they took 2 phase off of 3 phase they would be 120 degrees apart and be all wonky.
The transformer is really a single phase transformer with the secondary winding at 240V, the neutral is tapped in the center of the winding. So from one end to the center of the winding is 120V, the other end to the center is 120V (each of the 120V "legs" are 180* out of phase).SO explain how they get 240v with 1 phase and a neutral?
The first sub-division in Memphis to get air conditioning used commercial type AC units, which were 240 delta systems. So each house had two (2) services - a 240 Delta (Power Bank) for AC, and a 120/240V single phase for lighting and dryer/ovens/stovetops.There are center-tapped delta systems with a neutral for sure. Not extremely common but they are out there.
I had a 60 amp disconnect melt like that. The smell is noticeable (and likely causes cancer) clamped them together. The breaker is only 20' away. It's a conduit run, fastened... And melted. So the connection is in a outdoor box. (Plus there is a switch 1" above motor.)edited out................

We pulled the new copper in and when I opened the pole-drop to final the connex, the acrid burnt smell knocked me in the sinuses.
I asked my buddy how he knew the fuses were bad, and he said he changed them early this AM, but it didn't help and he did them another three times, not fixing the problem.
The screw clamps on the bottom of #2 leg was burnt so badly that the Bakelite stunk from the resistance-heating of a bad connex! This was the trouble all the time - just loose aluminum wires in the bottom of the SquareD connex on the customer's side of the fuses.

25 KVA is Satan's electricity and if you don't keep it busy doing something, it'll jump out and grab you! :notworthy:
I saw a trailer for a movie called "The Current War" today. You might want to watch- it pretty much gave the same impression. IMDB has it listed as a 2017 movie. I guess "Saataaan" must have some involvement.Electricity is the work of Satan, and those who understand it serve the Dark Lord.![]()
It is and an extra ground rod is not needed. Pounding extra ground rods all over the place does no good.When the gen is plugged into the house it is grounded by the house ground.
The ground rod still dissipates static if it was a generator. Lots of ground rods is good in general, it lowers the overall impedance of your ground which can help with things like lightning.View: https://www.youtube.com/watch?v=mpgAVE4UwFw
Long video but good. At 34:50 grounding myths are discussed.

At 49:57 is a little bit on generators
No, unless there is a power surge (e.g., lightning).... My question. It's very likely one leg gets much more load then the other. ...
Yeah.... I like Cutler stuff, but it had Square D in the room and I'm not gonna run his $$$ up any higher than that idiot CoOp 'expert' did with his bad diagnosis.I had a 60 amp disconnect melt like that.

Never use square D homeline for electric motors, any sustained load. I won't have it on my property. QO or cutler hammer. (I have bought old panels just for spare breakers)
I'm ticked the AC disconnects are $20. I used to buy them for $8-10
That is what was taught at one time but not now.The ground rod still dissipates static if it was a generator. Lots of ground rods is good in general, it lowers the overall impedance of your ground which can help with things like lightning.
So they are right why? They are on the internet?That is what was taught at one time but not now.
Myth 4 - More grounding is better is at 9:22 in the video.

Well also. They are wearing ties.So they are right why? They are on the internet?
In this case there is no "what was thought", better ground is better ground. What that means can certainly depend, in some cases it may create more problems than it is worth.Well also. They are wearing ties.
I find getting a couple certified experts (ideally government expert inspectors/ trainers) at a conference answering questions from a group. ( Bonas if the experts have not worked together for yrs, or are best friends). They will contridict each other. It's a hoot.
I used to get sent to multiple conferences. Most single daY. The arguments between experts helped the days pass.
I think he explains very well in the video why he is right and you just wont find anyone claiming he is wrong. Mike Holt is a giant in the industry and is recognized as an expert among experts. You will find all sorts of references to him from various sources for answers to electrical questions, answers to NEC code questions, and for education and training. He has a lot of good training videos on youtube that are easy enough to grasp for most. A lot of people think a ground rod protects against getting shocked. And most don't know that their if children weigh under 50lbs a GFCI wont trip and they can still be killed. Electrical safety is what most people should at least watch. Here is something on swimming pools.So they are right why? They are on the internet?
The first video is unrelated, he is talking about machines and use a ground rod to create whole fault and as he says that does not work. That is not relevant when using a GFCI. The other the section you pointed to, he does not know what he is talking about and just parroting NEC code. It is more complicated than he says. The answer as always is - it depends. For dealing with outlets outside run GFCI. I have never heard of the children under 50 lbs before, weight has little to nothing to do with it and besides I have tripped GFCIs before and felt nothing at all.I think he explains very well in the video why he is right and you just wont find anyone claiming he is wrong.
