Looking to buck 600 volts down to 480 volts. Do I need a 600 volt primary and 120 volt secondary trans former to accomplish this?
Existing now is 480 primary x 120/ 240 secondary which bucks to approx 408 volts

No, you need an electrician to accomplish this.
That is NOT DIY work and only qualified experienced electricians should be working on voltages and equipment like this.
Sorry for the frank advice.

Somehow, I think Sparky skipped class that day.

What in the world are you working on that's getting 600 volts anyway? I can't imagine that in any residence!

There's no way this is a residence which precludes the whole questions from a DIY standpoint.
If he is a contractor he needs a site for professionals like Mike Holt's.

Understood!

I doubt AMHD is "DIY", but the major title is "Home and Garden hence we would appear to be homeowner centric for 'electrical and Lighting".

Just like one can tell when someone is trying to their homework we can tell when people don't have a clue.

There have been some service entrance questions answered and some were not. It depends on just "How the question was asked".

If questions are asked about homework, it better be up front that it's about homework. We don't do someone's homework nor do we write someone's research paper.

Well, I consider myself relativley "handy", but I don't know all the codes, which is why I don't bother answering code related questions. I mostly stick to the basic ones, more over, issues that I have personally dealt with, and how I resolved it. Sometimes I just subscribe to questions in here just to see what the answer is.

I don't even mess with any service entrace, I keep my work below the main breaker. Anything beyond that goes to the pro's.

Same goes for plumbing. I'll repair any plumbing issue in my own house, but when it came down to replacing the water line to the meter, a contractor was called in.

Even in my job, I'm often exposed to 480 volts, but I've never worked on anything 600 or higher, and won't, as my tools are not equipted to handle that kind of voltage.

Regardless of the official stance of this site, I personally think the topic title "Home & Garden" falls easily under the DIY category.

If a "professional" handyman, or even worse a real electrician, comes here asking how to wire something, in my strong opinion he should not be doing such work for his customers.

At the same time, if a home owner comes asking how to wire something, given enough detail, we can/should certainly help them all we can. :cool:

Makes sense... I wouldn't want to hire an electrician to work on my house who has to search an internet forum of any kind as to what to do. Especially in a residence.

Exactly.
