I am working on a project installing a ton of lighting in a commercial warehouse being converted to apartments.
I have a problem with all of my AC low voltage lighting. It is flickering very noticeably. All the line voltage stuff seems fine. The problem is on at least two different circuits and moving the circuit to another phase has no effect. Shutting down the only large piece of equip. (cooling tower) has no effect. I did that because there was a time period one night when the flickering stopped.
I am thinking I have a bad neutral or ground connection somewhere in the building. I plan to do a visual inspection of all of the service equipment to look for visual signs of heating or bad connections.
Any other ideas of what it could be? Outside of a visual inspection don't feel comfortable troubleshootong this problem since it is after-hours work and I am not covered by insurance if something happens to me.
In the meantime I have instructed the owner not to use any of the low-voltage lighting for fear of damaging the transformers.
Thanks for your input!
