That should give you 2 of the 110v outlets. Ground is ground for both. Aloha! Al Plant - Webmaster http://hawaiidakine.com Providing FAST DSL Service for $28.00 /mo. Member Small Business Hawaii.

Re: [luau] any electricians out there?
The attachment was really cool and explained alotbut alas, I'm not an electrician and don't know how to interpret the diagrams. The bryant diagrams sent to me told the story of how the L21-20 outlet can either be 208volt or 110volt depending upon how you wire itI was truly hoping to find someone that can do a simple diagram on how to wire it based upon the five different wires in an L21-20 plug. I'm good at DC electrical stuffbut AC scares the @#$% out of meI'm fine at wiring it, but need someone that actually knows the stuff to tell me how to wire it up. /brian chee University of Hawaii ICS Dept Advanced Network Computing Lab 1680 East West Road, POST rm 311 Honolulu, HI 96822 808-956-5797 voice, 808-956-5175 fax
Re: [luau] any electricians out there?
This is what was forwarded to me by a guy that does alot of trade show electrical work: Does this plan make any sense to you? /brian chee start forward An L21-20 has three hot legs on different phases, a neutral, and a ground. The best way is to get a few of the doghouses that the electricans at the LVCC use... For cables, get some 12-5 type SO cable and a plug. Wire the green to the middle terminal, white to the silver one, and the others to the brass terminals. For the box, get a 3 space electrical box, install 3 duplex receptacles (don't use the 49 cent ones, use the $5 ones (spec grade or better), connect green to the box and all three green(ground) terminals, the white to the silver-colored screws on the recep's and the black, red, whatever the other color is (usually red or orange), to the brass screws on the recep's. end forward University of Hawaii ICS Dept Advanced Network Computing Lab 1680 East West Road, POST rm 311 Honolulu, HI 96822 808-956-5797 voice, 808-956-5175 fax - Original Message - From: LinuxDan [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, February 18, 2003 1:57 PM Subject: RE: [luau] any electricians out there? Brian I messed with plenty electrical and was an electrician for a while in the Midwest. What can I do to help you. I actually rewired half our apartment and grounded it properly to setup my home network. I have a unit in every room and will now rewire some of the existing units. But whatever I can do to help, please let me know.

attachment at http://whoever.net/outlet.pdf your system might be just using two phases out of three. -- Forwarded Message -- Subject: Re: [luau] any electricians out there? Date: Mon, 17 Feb 2003 22:17:34 -1000 From: whenever [EMAIL PROTECTED] To: Brian Chee [EMAIL PROTECTED] are you talking about three phase L2120R ? you can find it in the NEC book, I had my book at work, but I found a pdf that show it on page 14. Becarefully on isolating the different phases and don't cause a short, phase-phase is 208v, any phase to sys ground is 120, reversing the hot and netural will make your equipment case hot. If you are taping in without a outlet plug, even it's a temporary, you should know the requirment from the NEC book first, if anything happens, insurance might not cover it and you could get in big trouble. good luck On Monday 17 February 2003 09:12 pm, Brian Chee wrote: I'm really having problems finding the wiring diagram to take an L21-20 electrical plug (5 wire, 2 hot and 2 neutral with a ground) at 20amps 208volts.
