I happened to be working on my main amp rack when I saw this. So here is how I do it.

I have 3 quads split evenly among the 2 circuits. Both edisons are 10 gauge. I can run this rack plus FOH, two monitor amps, and backline power from this setup. This is for a typical country bar band, and my bass player runs direct, so there is no bass "rig". Two solid 20 amp circuits do fine. If the power is sketchy I need 3 circuits. I'll put backline and monitors on the other circuit.

These are the main amps. 2 PT2400's and 2 PT1800's. That's 1200 watts x4 channels and 900 watts x4 channels. The amp literature says that a 2400 at full tilt boogie will pull over 50 amps from the wall. In practice it's been just fine running all this on 2 20's.

The biggest problem I have is that these amps are so front heavy, that the sleeve keeps wanting to fall out of the case!

So I got quotes back today and now I'm confused.
I have a $120 difference in two products.

Tripp Lite makes a distro with 12ea NEMA 5-15/20R, a 20a breaker, a current indicator, and an L5-20P on a 15' cord.  No switch, no MOV.  Just plain distro.

The Motion Lab is $60 more, has a smaller breaker, less edisons.

I'm all for buying Motion Lab products, since that's rock and roll and the testimonies tell me I can't get any finer.  But the $120 I save on a pair of devices can go for the fancy panel I need, all the cool plugs and jacks, and gas to go parts chasing.
The ammeter is a bonus.

My rack has two 30a twistloc's on it. Distro has two 30a circuits on it. Also have two adapters, 30a twistloc females to male edison for small places without tie in.  

One circuit has PL9+FOH and the other has PL4,PL2.0HV and Dbx 260.

Yeah, I was looking at these today

I think the project will evolve into two parts now.
Internal distro first, since I must clean up the way I power these amps.  And the patch panel will come in phase two.

It's a big rack, I think it's worth 3 L5-30s and 3 30a breakers.
Yeah it should feed FOH too (but shouldn't this come from here anyway?).

Yes. In fact you should power everything from there. Backline included. A single 20 will suffice for backline. Even if you run into full marshall stacks, and twin SVT rigs.

Don't forget to plan for extra circuit's for upgrades down the road. You might want delay stacks, or a monitor world later on...
