Star Wired/Grounded Power Strip?
« on: 29 Nov 2011, 05:28 am »
Hi All,

First post here.

Do any of you happen to know of an affordable power strip that is star wired and/or star grounded?

DIY would be fine as well...

Thanks!

I always recommend building your own.  That way you KNOW what's in there.  Home Depot, Menards or Lowes is where you start.

Get some of this stuff and have at it with your favorite receptacles - preferably Industrial Spec Grade or better:





Use at least 12ga 3-wire electrical cord and a good Edison plug and don't forget to put some bumper feet on the bottom if you have hardwood or tile floors.........

Have fun   8)

For a nicer looking enclosure, many of us prefer to use outdoor die-cast aluminum boxes and stainless steel covers.

This is exactly the kind of info I need - I really appreciate your help.

Anybody have any recommendation about methods of joining the live, neutral and ground leads in star config (respectively, of course :D)? Would something like a "copper bus bar" be appropriate? What about some sort of endcap where all the (respective) wires converge?

Also, at the risk of veering off topic, if you wouldn't mind I would really like to know any of your thoughts about MOVs and mains filtering (XY capacitors, corcom style "purifiers", etc)...

Thanks again!

That is very cool, I hadn't seen that one!  No cover needed and has opposite outward facing receptacles that can accommodate multiple transformers and/or right-angle plugs.

It is a good one too, Steve.  I used to use the Leviton version of this on my BUSSes when they first came out, but the quality deteriorated on those.  If I need a quad for a project, the P&S is the one I use.  They are available in black, white, gray, brown, ivory, red and orange.

Here is a great resource for all of the brands - their pricing is pretty good:

You would have to inquire about the wiring but these http://signalcable.com/magicextension.html are a really good deal and they're UL listed.

Thanks, I thought about that one, it does look nice - but I think I'm going to go with one of these:

http://www.newark.com/jsp/search/productdetail.jsp?sku=36C2908

largely because it has an extra grounding lug, which will be convenient to hook up a particular rack shelf chassis that needs to be grounded.

If that's the case look at this http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=190577644440&ssPageName=ADME:L:OC:US:1123

I just got one for my soldering bench.

Shucks.. Now I'm wondering if the Hammond is such a good idea at $62. Supposedly it has "hospital grade" outlets. Would this actually make a difference do you think?

So I have another stupid question - if a PDU is rated at 20A, does that mean it needs a wall socket that is wired to handle 20A, or would a 15A wall socket be ok provided that the total current draw were within the limits of the socket?

A 20 Amp plug will not fit in a 15 Amp receptacle.
A 20 Amp device needs a 12 AWG cord.

What are you planing on plugging into this?

It may be rated 20 amps and have a "normal" plug on it.  If the dog-leg portion is on the plug per the 20 amp rating, then you'll need a 20 amp receptacle.  There are plenty of devices out there rated at 20 amps with "15 amp" plugs on them.

Here's a true 20 amp plug and the 20 amp receptacle.  Note the one leg is turned 90 degrees on the plug.

It's an external power supply rack with three linear Acopian PSUs for a mixing console.

Funny.  I was just looking at the Acopian LPS last night.  I think any of the units linked will work fine.
