[RE-wrenches] meter pan?

[Dave Click]

I guess someone could argue that 690.15 would require a disconnect on 
both sides of that meter, but for this install, the line-side disconnect 
would immediately trip the inverters offline, so you can't really say 
that the meter is "energized from more than one source" like a DC 
disconnect would be. I'd say your fused disconnect would be all you 
need. Does your utility/program really allow you to put the production 
meter in the basement?

Is anyone using the Milbank load-tap connectors yet? Part# K4977-INT 
allows for up to a 100A load-side connection in a Milbank 200A meter 
socket. It looks like it would be the best/easiest way to make these 
connections with caveats: get utility's permission before you open the 
socket and pull out the meter, and be wary of the very live voltage on 
the line side terminals.

(hat tip to Eric Thomas, who I now see posted about this last April-- I 
don't see that anyone's commented on it since)

Also, note that the tap rules don't apply here, so you're better off 
calling it something other than "tap" when talking with your inspector.
