Do I want a Loadcenter or a Panelboard? That is the question!!
What is it all about?
A "UL" perspective, for non-hazardous areas.
What dose the spcification call for, what is the AIC, and voltage required?
Is selective cordination required by code?
Then you need a panelboard.
Is this a critical circuit for process control or life safety?
Then you should use a panelboard.
Do you need lighting controls with remote control breakers?
Then you need a panelboard.

SEC to A&M, "not on the first date"
Hey Man,
It looks like breaking up is hard to do. TV contracts have to paid off, maybe $30 million?
A&M has to face questions from The TX House Higher Education committee chaired by Dan Branch. A lot of public money is in play here. I don't want to subsidize the Aggie feud with UT. Chairman Branch wrote HB 51, the Tier One Universities bill. He is a grad of Oklahoma Christian, SMU law and is an alumnus of the Institute on Comparative Political & Economic Systems at Georgetown University.
He may ask hard money questions. The Aggies need to have enough guaranteed from the SEC to pay off the TV so the rest of us aren't robbed in this deal. I hope they can pull it off.
Let's see the future holds.....
PAC-16, The BIG(10)-16, The SEC-16, The ACC-16, The BIG EAST-16, and no Big 12.
cheers

UH in A&M out of the BIG12?
Hey Man,
There are some interesting stories out and the tide(not The Crimson Tide) is turning the other way.
From Kristi Reiken on Rivals.com
"State Rep. Dan Branch, the chairman of the Texas House Committee on Higher Education, called a hearing before his committee for Tuesday with Big 12, SEC and Texas A&M officials. Texas A&M soon moved up a meeting of the board of regents from Aug. 22 to Monday that includes an agenda item about conference realignment.
He said it would be “inappropriate” for Texas A&M to switch conferences before the hearing.
Also on rivals is a story that Playoff Pac has filed suite against the Fiesta Bowl and state schools who played in it.
Another story on Rivals quotes unnamed SEC sources that the deal is less likely now than Friday. One thing is the 14th school is not a done deal.
I say, the BCS may be busted before we get in.
Go Coogs!
