[QUOTE="Chris Van Duker, post: 57211, member: 1113"] Re: L14-30 or CS63## power distro (small to mid sized PA systems) Since you already have a pile of 4/4, I'd go with the CS connector-based distro. In addition to some of the other benefits which others have listed, there's also the fact that when you're far away from a power source, the larger cable will give you a stiffer mains voltage. The longest feeder I've ever used with my small 2x30a L14-30 distro is 125 feet, and I was getting significant sag with that. Also, if you're tying into 2 legs of a 3-phase supply, your neutral isn't exactly "between" the two hots, so it carries more current, and becomes a bigger part of your line-loss equation. Also, if you're using the Crown Itechs you mention in your footer with this distro, you might want to consider setting up your distro to run them at 240V. I've occasionally popped 20a breakers with my IT8k's when running them all-out on sub duty, when they're on a long AC run -- the regulated PS seems to draw more power to compensate for the voltage sags. If you run them at 240V (or 208V, if you're on 2 legs of a 3-phase supply), you're a lot further away from the 20A breaker on the back of the amp, and you're also balancing draw against both of your supply legs by default.
