Cotton <br />Subject: RE: Providence A-Wing UPS replacement -- E1301-178 <br />Attachments: A1CH1.pdf <br />Tim, <br />Attached is the panel schedule far Panel A1CH1. Note that this panel was instailed in 2008 when the "newer" 40kVA <br />UPS was installed. At that time, we used a load for the 11PS of 40kVA and carried it through the calculations. <br />The current project will not be adding new load to the facility; the hospitai is actually pianning to decommission some of <br />the equipment in the Server Room that is currently being fed out of the "newer" UPS. A summary of the load revisions for <br />the project is as foilows: <br />- The "old" UPS (30kVA} is currently fed from Panel CP1 (connected to Bus #4 of A-Wing distribution). This UPS will <br />be demolished. <br />o Currently twa laad c�nters in the A-Wing MC7F are served from this UPS. �hese feeds will be moved to the <br />"newer" UPS as part of the praject. <br />_. Ofiher circuits that are fed from the "old" UPS will be moved to Panei CP1 as part of the project. <br />- The "newer" UPS (4QkVA) installed in 2�08 is fed from Panel A1CH1 (connected fio Panel NCC in C-Wing). <br />_: The loads in the A-Wing MC7F will be moved to this UPS {project wi61 repface the two load centers with new <br />panels; laads remain as is}. <br />_. At the time Panel A1CH1 was installed, 40kVA of laad was shown for the 11PS in the C-Wing load <br />calculations. [We were nat sure how much equipment the IT staff would be installing, so we assumed a <br />worst case of a completely loaded system.] <br />_ Subsequent to this project; the hospital will be moving equipment aut af the Server Room, reducing the load <br />on this UPS. <br />Let me know if you need additionaf information. <br />Maureen D.

Jackson <br />Cc: Tony Lee <br />Subject: Providence A-Wing UPS replacement -- E1301-178 <br />Hi Maureen, <br />Could you provide me with load calculations for the A-wing UPS and affected panels. If the demolished UPS was fed <br />from A1CH1 then calcs for the UPS will be sufficient. <br />Thanks <br />
