Looking at the specs for the compressor I will need a 250V fused disconnect with 70A type k5 fuses and an 80A GE THQ 3p breaker. I will also need a 4/3 SO cord that is approximately 20' in length for the connection. I will check to see if I have any of these items in our overstock, but if I do not, I will need to get them purchased.<br></div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><br></div><div data-marker="__SIG_PRE__">Jason Willoughby<br>FM&L Electrical Engineer<br>Thomas Jefferson National Accelerator Facility<br>628 Hofstadter Road STE 1<br>Newport News, VA 23606<br>(757)-269-5372<br></div><br><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>From: </b>"Brian Eng" <beng@jlab.org><br><b>To: </b>"Walt Akers" <akers@jlab.org><br><b>Cc: </b>"dsg-rich" <dsg-rich@jlab.org>, "Jason Willoughby" <jasonw@jlab.org><br><b>Sent: </b>Friday, May 12, 2017 10:08:15 AM<br><b>Subject: </b>Re: [Dsg-rich] Power for air compressor in EEL rm 125 (Bertha Unit)<br></div><br><div data-marker="__QUOTED_TEXT__">I sent the manual for the compressor to Walt and Jason already (it does say that it is suggested to stay within 5% of nominal and must not deviate more than 10%, so maybe it's okay?).<br><br>However, Tyler is contacting the company to get more information regarding supplying 208V 60Hz instead of 200V 60Hz.<br><br>> On May 11, 2017, at 1:20 PM, Walt Akers <akers@jlab.org> wrote:<br>> <br>> That's a step in the right direction.
