SUBJECT: Power distribution for V24 system


   In order for ISI to change manufacturers of AC distribution panels, I 

need to know the type of connector desired on the AC cable. The choices 

are as follows: 1) Standard 3 prong connector rated @ 12 Amps, 
                2) NEMA 5-20, a 3-blade connector rated @ 16 Amps,
                3) NEMA 5-30, a 3-prong twist-lock rated @ 24 Amps.

For a maximum configured V24 we should be using a 30 Amp panel and a

twist-lock connector. This is per the National Electrical Code which states

that no one device should draw more than 80% of the branch circuit capacity.

   Customers should be advised when ordering a V24 they must install a

dedicated 30 Amp AC circuit for the computer.

   Please discuss this with all appropriate staff members at your Tuesday

meeting.
