[RE-wrenches] Utility External Disconnect Switch

[Dan Fink]

Hello Joel --

Well, you can be assured that both NREL and IREC are on your side. They 
were very convincing about dropping UEDS requirements at this seminar. 
Funny how utilities can require UEDSs, but none of them have the 
procedures, personnel or infrastructure to actually *use* them.

Imagine a 'green neighborhood' with PV on each of four dozen homes. 
Figure at least 10 minutes each for the utility to locate and tag / lock 
out each UEDS...and the same to re-commission them after the incident. 
And how many utility trucks carry 4 dozen locks?

I won't go into any more UEDS issues here, but I will be writing about 
them soon and publish the link here on the list.
