There was one mention that a 4060 consumes somewhere around 2000 watts continuous. For a very rough estimate: 2000 Watts / 36 Volts = 56 Amps. 56 Amps / 60 channels = 0.93 Amps per channel. (Obviously this is just an estimate. The center section and the rest of the console are using some of the power as well.)
As to "amps" on the AC side, 2000 Watts / 240 Volts / 80% efficiency = 10.4 Amps. (No idea if the power supplies are actually 80% efficient. Just a guess.) This does not account for inrush current (charging capacitors) when switching on the system. It would not surprise me if a 20 Amp, 240 Volt circuit is required to prevent tripping breakers.

You would only need a 20A breaker if the desk comes online all at once.
But don't forget you really should switch your desk on in stages.
First the centre section with a 1-2 bays and only one PSU. (never switch on the first PSU with no load, always 1-2 bays at least on) Then the second PSU and the rest of the bays (8 channel at a time), and finally the PSU for the computer.
That way there is no way you would trip the breaker.
You have to put in circuit breakers so that in the event of a power cut the SSL doesn't come back with the full load at once, once the power is restored.
They can be bought at any DUY store at a couple of $.
What happens if there is loss of power you have to reset the switch by hand, which gives you a chance to switch the SSL PSUs and channels (or at least some of them) off before the power comes back.
I haven't seen many studios using them and that is one of the reasons why their desks and PSUs keep breaking down.
Here is an example of such a switch:
Axminster NVR Switch : Buy Axminster NVR Switch at Axminster Power Tool Centre
Another important tool to have is a thermometer sensor in the machine room with a beeper/alarm in the control room once it's getting to hot in the machine room.
Do you know how often I switched off the A/C and forgotten about it?
Or what if the A/C fails and you don't know?
That's all you need:
Multi Channel Thermo/Hygrometer with alarm (EMR899HG) : Thermometer : Weather : Oregon Scientific Quote:

Based on that, I can see how a 60ch board could use every bit of 120 amps.

And can we please stop spreading bullshit like this?
You guys never owned an SSL or seen the real numbers, I guess.
You are doing the community no service with such highly incorrect figures. The real figure for a 60 channel desk is: 8-9 Amps (240V) and 18-20 Amps on 110V. With all the PSUs in the SSL rack on. Totall Recall, G+ computer, the lot.
Anyone saying somthing else has to come up with more evidence than hearsay or his/her wild imagination.
