Today I found 3 power cables in the orange Pomona cable tray, put in so that the cables were damaged and therefore dangerous.
Please think about what you are doing before doing it. Damaging these things because your are in a hurry or frustrated will just waste our time and damage our interferometer.
For reference, we only use the thick blue Pomona racks for power cables. We use the orange and black ones for thinner cables. Pay attention and keep the cables organized.
