I'm sure your electricians know about<br>
it, but just in case it's worth noting. When you get a brownout and the<br>
transformer switches, your Amp draw will go UP by about the same<br>
percentage as the brownout goes DOWN. Not a problem unless you're<br>
running close to full capacity and you have a deep brownout.<br></blockquote><div><br></div><div>Yep.

(Convert to U.S. figures as needed)</div><div class="gmail_quote"><br></div><div class="gmail_quote">As you might guess, we need one interpretation (127V per leg) while the drawings specced another (220V per leg). Which meant that a required 50kVA transformer was not in the drawings, or budget.</div><div class="gmail_quote"><br></div><div class="gmail_quote">Michael S.</div><div class="gmail_signature"><div dir="ltr"></div></div>
