Joe90's BIG RAT Build.

Wow that's some serious brewing activity...

Don't worry about phases in your calculation. Just take that single phase value, 4A or so and go with it.

If your Calcs end up needing more than 1000kVA you're probably not quite right, or you're building a beast. Most builds here use around abouts 500kVA.

I won't comment on the information you've already seen from my build log - no point hearing the same persons opinion twice. Although I will add that I think I was a little conservative with my secondary voltages in retrospect, and could have gone higher.
