I'm leaning towards buying two new D20 modules and wiring the 575's 3 to a circuit rather than 4. That's a solution I should have listed in the original post.I'm very much inclined to agree that headroom needs to be present in every design no matter what the manufacturer specs are.

I'll test the incoming line voltage and report back.

Thanks John! I will test the system using the Unison control panel and report the results. In addition I will check the menu settings you suggested. I'll also research the install and verify the NEC code in my area. All great observations. Thanks!

120volt lamps. GE HPL575X-C. I'm arranging a lift and a twofer to get to the outlets to verify voltage and physically verify that all lamps are that model.

The system is appx 5 years old. No changes to it. It was installed with 575 watt lamps. The tripping has been going on for some time now.

Does anyone even make a 375 watt 120 volt lamp? Or am I going to have to use a 375 watt 115 volt lamp?

I'm posting this here because I was told that many ETC folks are around. I also chose Design Issues and Solutions because, in my research, I believe this lighting system was not designed with the 80% load rule in mind.Hi all! We have an ETC Unison DRD 12-24-120 with 10 D20 modules and a CMeD...
