I wish I could find a chart or list more like that for twist-lock connectors. The connector used on the cord for the main power supply in my 4D/210S is the third connector listed on that page: "IEC 320 standard sheets 19 & 20 describe a connector rated at 16A/250 (20A in North America) It is rated at 65oC and permits detachable power connections for higher power products." -Toth

The Aussie/OZ site that I first found info on them from calls them heater cords, so obviously they are in common use where a removable cable is needed on a high current device/appliance. Of course everyone has their own odd plugs to go to the power receptacle, go figure. I'd really like to find an attachable (screws/solder/etc) type to put on my own cable and I could even wire this to a disconnect/safety box on the wall and make it doubly safe. I'm running the server with one of the 410 watt redundant power supplies out right now as it's not need yet and saves the curent draw from 12 amps down to 8, making the 18 AWG cable safe since I heated ina groove with a soldering iron and then trimmed the melted flash off t he sides of the groove. -----Original Message----- From: owner-classiccmp(a)classiccmp.org [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Matt London Sent: Monday, January 28, 2002 10:43 AM To: classiccmp(a)classiccmp.org Subject: Re: Need source for high current HP type (with dimple) 14 or 16AWG 110vac power cord Hi, Here in the UK they go by the canocial name "Kettle Plugs", as the higher current (15A?) version is most frequently found at the end of powercables for electric kettles (you know, those things for heating water). The name is frequenly extended to the 5A version as well (the one everyone is familiar with) Also in common usage is a "hot to cold cable" :&) I'm sure everyone here can figure that one out. -- Matt --- Web Page: http://knm.org.uk/ http://pkl.net/~matt/

Jameco has a 14/3 2.5m power cable in black for $3.95 each, part number 125541 but they use a generic pic for the illustration so I don't know that it has the notch but I can put that in if not - I just want a cable that has the cajones to handle the juice I send through it. They also have my heatsinks so it's time to cut an order - they've been faithfully sending me expensive catalogs for years and I haven't ordered from them in probably 2 of the last years. It appears that most of the US shipped/made heating devices have either a proprietary plug or are wired fixed with a restraining grommet (I know there's another name for them, I can't think of it). I even checked with an appliance dealer here - no good they didn't have aclue even after I faxed them the end view of the plug with an arrow to the notch I needed to pay special attention to -makes you feel good about the "experts in the field" whn it comes to high current appliances huh? -----Original Message----- From: owner-classiccmp(a)classiccmp.org [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Matt London Sent: Monday, January 28, 2002 12:03 PM To: classiccmp(a)classiccmp.org Subject: RE: Need source for high current HP type (with dimple) 14 or 16AWG 110vac power cord On Mon, 28 Jan 2002, Russ Blakeman wrote: needed my wall Again - commonly available here in the UK.

Adding or removing drives and boards would change the max current draw. With two power supplies handling the load instead of three, the two just end up taking more of the distributed load. The 12A current draw I imagine is the max inrush rating, not what the unit would normally draw. HP would have come up with this rating by completely loading the system with the max boards, drives and memory that could be added, checking the inrush current draw, then adding some safety margin to that. You really should check the systems present current draw with an amp meter, however. -Toth I pondered that too but since I have a proper cable coming in with my heatsinks for the added Pros and 2 50 pin SCSI -I headers to an external HPDB50 SCSI-II for my Microtest 14 cd tower then within a week I'll have the thing hooked to a separately breakered circuit in the shop (instead of the living room, as much as I like it as a side table). Once it's in place I'm going to Win2k server which is why I need the SCSI adapters since the interface doesn't have updated software (discview) support for anything other than Novell and NT 3 and 4. The adapters allow me to swap it back to original if I decide to stick with NT 4 server too rather than chopping things up to make it a standadrd style cabled rack.

It appears that the grade of a recepticle (now, that _can't_ be spelled right!) is based in part on how tight the device pinches down on the prongs of the plug. Perhaps a similar rating is being applied to the cord ends? <USA> It's the cordset as a whole that's limited by the lowest rating of it's parts. Use 14 AWG and by the NEC it's limited to 15 amps, even if it had a 30 amp cord end on it. It might be possible to get IEC cord ends and roll your own with something like #12 wire. </USA> I have an adapter to hook a 20A recpt to the service drop coming from the pole... Quite handy at times. :) Bob
