[QUOTE="Marlow Wilson, post: 30815, member: 47"] Re: L5-30 wire for 220V? Each leg is 120v to neutral or 240v between legs on a regular split phase. It's like bridging an amp - you double the voltage. The ground is always there for safety and must always be there. Like the neutral, you'll get 120 to ground because they are bonded at the service entrance. Apart from needing the ground for safety, the ground, for a number reasons, is unsafe for use as a neutral. Some people will do something doubly dangerous by using the ground as a neutral (you then have a dangerous neutral conductor and no safety ground = BAD F***ING IDEA). The 208 volts is because it's two legs of a three phase service. The phase is offset, so they do not perfectly double. (This is a really truncated explanation) I really suggest you read up on different types of three phase services. This is a great book: "Electricity for the Entertainment Electrician & Technician" [url]http://www.amazon.com/Electricity-Entertainment-Electrician-Technician-Richard/dp/0240809955[/url] If you need the motivation, I thought the book had one of the best prefaces I've read in a while: [I]There’s an ancient story of a martial arts master who attempts to give one of his students, the “chosen one,” the secret to harnessing the power of the universe. But the two of them discover that the sacred scroll con- taining the secret is nothing but a blank reflective surface. Eventually, the student realizes the true meaning of the scroll, that the power of the universe is already inside of him. Armed with this newfound knowledge, the student becomes the master and defeats the evil warrior. You may recognize this ancient story as the plot of the movie Kung Fu Panda. Yes, I realize that it’s a children’s animated movie about a noodle- making panda bear with no formal martial arts training who is chosen over five highly skilled experts to fulfill a prophecy by defeating the villain. And I do realize that the movie is designed to appeal more to the funny bone than to the think muscle.

I couldn’t help thinking that its message, that the greatest power is inside of us all, is exactly the message that I want to convey to you, the reader, about this book. The “sacred scroll” that you now hold in your hands is nothing more than a highly reflective surface. It merely reflects the incredible power of your mind to visualize, analyze, and comprehend. That power is inside of you, and my hope is that this book will help you bring it out. But before you undertake the journey through these pages, take some time to reflect on what it might take to reach your goals. How much effort are you willing to put forth? How much time can you spend each day working to achieve your desires? Someone once said that if you’re interested in something you’ll do what’s convenient, but if you’re passionate about something you’ll do whatever it takes. No student has ever mastered a subject without making great sacrifices. It takes time, dedication, hard work, contemplation, and concerted effort. It’s no different whether we’re talking about the martial arts, theatre arts, per- forming arts, or the art of mastering electricity. The information contained in this book is not difficult, but it can be challenging. Some of the concepts can challenge your ability to straddle the line between abstract thought and real-world application. But if you love the production arts as much as Po, the kung fu panda, loves food and the martial arts, then you too are capable of impressive feats of art- istry. All it takes now is for you to see your reflection in these pages. So I challenge you to dive into this book with the same enthusiasm as a panda bear fighting for a dumpling. Namaste.[/I] [/QUOTE]
