Hi all,

Need some quick wiring assistance please...

I recently picked up a used reflow oven (APS GF-12) and it does not  
have a plug -- just 3 bare wires (12ga white, green and black).  The  
prev owner said it was hardwired and thinks it was 3-phase, but IIRC  
3-phase requires 4 wires... or not???

I have 2 options for outlets here at the office...
(1) a Nema L6-30 ( http://www.ezdiyelectricity.com/?p=238 )
(2) Another similar outlet, but the prongs are in a smaller circle.   
It says "Hubbell twist-lock 20A 250V plug".

So I ask...
- Is this oven a single-phase oven? (APS only made these as 220V  
single-phase or 220V 3-phase).
- Is there a standard for the colors on the plug wires?
- Is there any way to check the oven  for the correct phase  
requirements (resistance tests, etc) before I damage the oven?
- Are both of these outlets single phase?
- Which wires should I connect to which prongs on the plug?  Assuming  
these plugs are available quickly.

Google hasn't yet given me any definitive answer.  I have a few days  
left on my DOA warranty, so need to test fast, and APS won't speak to  
me unless I give them $2000 first.

Much thanks,
-Neil.
