Thanks for the response, Jason.

Were that a CEM+ or CEM3 installation?

I just checked the power feed to the theatre. It appears to be 600 Amp 120/208
3 phase.

The feeder to the two 2400 watt 12 packs - is probably 208 V at 125 amps.
(only two breakers). That seems awfully low for the system, but we have never
had problems - possibly due to the lack of instruments to fully load all the
dimmers at once.
