[RE-wrenches] Optimal 200 or 225 Amp Square D MSP All-in-One meter for CT Clamps

Thu Feb 18 10:36:33 PST 2016

The Eaton "Solar Power Center" panels are combined meter/main service
panels that can accommodate consumption CTs, if you know the trick.  What
you need to know about those panels is that the main breaker internally
rotates the line conductors, so that line 1 is on the right on the top of
the breaker, but line 2 is on the right on the bottom of the breaker.  This
panel doesn't appear to accommodate consumption monitoring CTs, but if you
install one CT above and one CT below the main breaker it will work.

“Don’t get me wrong: I love nuclear energy! It’s just that I prefer fusion
to fission. And it just so happens that there’s an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it’s wireless!”
