Re: uninsulated overhead grounded conductor

Bob, I am not about to get another list started. I got into a list on another post and I refuse to do that again. Notice that I said that Ed is one of our most respected members, I didn't mean he was the only one. :D

I usually work with people all younger than myself, 18 to 30 year olds.

It is nice to be considered 'to young' at 40. :D

I don't hear that often considering my hair is pretty gray now. :roll:

Charlie, the only thing I was going to bring up this time is that I wouldn't have thought you were much more than a little over 50. :D

Edit: left out a whole word

Re: uninsulated overhead grounded conductor

Ed, your points are well taken but there were personal references made to me in previous posts on this thread that had nothing to do with the subject at hand.
Now, you chart is correct of, of course. Review my posts and you'll read I wrote the nominal voltage for most services was 240 and I capitalized every letter of nominal. For the purposes of many motor manufacturer 230 is nominal. That is why many motors are tagged 230 volts. I sent you links to a catalog for single phase motors used on condensor fans. In fact I've sent, and can send again, thousands of references to 220 volt service. Look, if I wanted to nit pick I could go to any text of electrical practical theory and find things that are not literally correct. For example, it is not literally correct that electric current is only the flow of electrons. If it were, a car battery wouldn't work, to say nothing of transistors. Nevertheless, I teach it and say it because it simplifies a more important discussion.
Look, if this thing with 220 volt service still makes anyone suspect, I'll send you to a site referenced by the electrical inspectors for this nation that makes reference to 220 volt services.
All this is not to say you don't have a 240 volt service in your neck of the woods or that it is not a common service voltage or that 240 is not a nominal voltage. 208 volts single phase is still fairly common and 220 volts was at one time very common.
Voltages are pushed to their highest limit to keep conductor size to a minimum. When copper prices went through the roof the manufacturers and utilities saw their bottom line in trouble. To them, 240 volts is lot more appealing than 208. Remember they sell KVAH and it takes less copper to deliver KVAH at a higher voltage.
By the way, if I really wanted to get heavy on safety, I'd get into aluminum, and if you want a gut opinion from me-I'd outlaw for electrical use.
This c--- started in wide use in the sixties.

Re: uninsulated overhead grounded conductor

Bgisborn, if you will go back and read the previous posts, you will see your slang term of 220 v only prompted a question as to what your title actually means, which you have rudely evaded. Answer the question and us young guys (by your definition, and I like it ;) ) may decide to give you credit.

Continue to ignore our questions and you will continue to be treated as a rude person.

Sorry to bring courtesy into your old set ways, but give it a shot.

BTW, Charlie pointing out our respect for ED may be an understatement and Charlie is as well respected. Not that it has any bearing on the reason for respect, but you should look at who makes up CMP 10.

I thought it was pretty cool when I first found that in the book. Charlie's rather humble about whole thing. :cool:

Charlie's "The Man" :cool:

There are other CMP members that stop by and many members with equally impressive backgrounds.

We are lucky to benefit from the years of experience that come together here.

Check out some of John M. Caloggero's past.

Try a Google search on many of the members here and you often find out they are very busy people. :cool:

I actually got a little concerned about certain individuals' privacy because there is a lot that can be found out about some of the higher profile people here. I hope that by itself isn't saying too much.

Re: uninsulated overhead grounded conductor

Sam I certainly would not try to violate someones privacy.

IMO if someone has taken the time to post with their real name or include it in their signature they are not concerned with that. :)

Re: uninsulated overhead grounded conductor

You guys are really embarrassing me. :)

I want to point out that the 240 volt nominal voltage is what a standard transformer will put out with the rated nameplate voltage on the primary side without load. We pump out 13.8 kV on our primary lines at the substations and feed 7.62 kV - 120/240 V transformers (13.2Y/7.62 kV system). The nominal is still 240 volts and we have an overvoltage to the customers close to the substation. We can run that circuit almost twice as far before using voltage regulators to boost the voltage back up.

We guarantee (by law, Bottom of page 13) the voltage to within 5% (6% in rural areas). Now what is the supply voltage? It is within 5% or 6% of nominal on our system. It is normally the uneducated people that use 220 or 230 volts to refer to the supply voltage. :D

Editted to bring this post to this page.

Bgisborn, You've got to be kidding, So after all of this, you are saying you're a home inspector?

Some how this is a perfect fit. :D

Bringing this post to this page too.

Call me a skeptic but I will believe Ed and Charlie's information before I believe the home inspectors site. :D

Is that the deal?

You are a Home Inspector?

Re: uninsulated overhead grounded conductor

You were expecting ice cream vendor, I presume? :D

So, Bgisborn, have you encountered any anecdotal or other evidence of an uninsulated neutral breaking free on it's own and shocking someone?

It seems like whenever I get bit in my job it's from the tips of insulated conductors that I presumed were off!

Re: uninsulated overhead grounded conductor

From the Home Inspection Supersite
Going back to our analogy of tunnels, think of a small tunnel as one that is large enough to accommodate cars, think of a large tunnel as one that is large enough to accommodate trucks; that is, the small tunnel is analogous to 110 volts, and a large tunnel is analogous to 220 volts.

Bob, I hope that whoever wrote the Electrical Page (Amps And Volts) is not one of their "engineers".

I realize that it is directed at the homeowner, but even so, that isn't a great analogy for explaining voltage.
