hey all. i kno how to figure out my amperage and stuff like that but what is throwing me of from the instructions is the "single phase circuit" can anybody explains what this means. i don't know too much about electrical technical info. but do i still have a total of 100 amps or what?

Please see the following article about single phase power. Copy and paste into your browser. [URL=en.wikipedia.org/wiki/Single_phase] Just about all of the lighting fixtures you will be using is "single phase". Unless you are getting power from a large main panel and not going through a power distro (which is recommended) you will be using single phase power. So that means that you will need to add up the total amp draw of each fixture that will be active at the same time plus the load of the dimmers as well. As long as you are never over 100 amps of load you should be ok. But (and there is always a but...) I would suggest that you allow 5% minimum for voltage and amperage differences of service power. It may not be a concern for a demo in software but if someone tried to run it live it could hurt the performance.

so really try not to go over 90 amps just in case? thanks and welcome to the forums.
