Hi Bob,

I'm not sure about the latest EZWire centers but 
if it's anything like the earlier ones there is 
very little clearance between the aluminum case 
and the rectifier bodies in the unit which are 
all hot.  About 1/4" separates them at the 
tightest places as I remember.  On top of that, 
the cover hinges on two little screws at the back 
top (or was it bottom) of the unit in such a way 
that if you lose one of those screws (easy to do 
and not notice), the case can sit askew and come 
in contact with the hots.  I discovered that the 
hard way one day when removing the case without 
shutting down power (and my case was grounded). 
It's also really easy to drop a screw in one of 
those units and it gets lodged between the case 
and the rectifier bodies (hots).

Hope that's all it is.  I can't say I've eve been 
very impressed with EZwire centers - no UL 
approval - diversion regulator often doesn't 
work, meters were often inaccurate (they used 
wire length for shunts in the unit), and the case 
to hot contact risk.  Was hoping SWW wind would 
upgrade someday.  Anybody listening at SWW?

I'm actually about to replace an EZwire center 
that we recently lost in a power shed fire. 
Anyone know of a good equivalent replacement? 
It's 48V - all I really need is to rectify - I 
could do diversion with another controller. 
Anyone know the specs or have experience for a 
replacement rectifier for a Whisper 3.2 KW? (240 
Volt Wild AC to 48VDC?)

Best,

Jeff C.
