I tWhat we really want is a battery capable or running out chain, (no load) on a couple dozen motors without recharging. A powered pickle!

My biggest issue with what I see is the side loading of the wire rope thimble. A small shackle would fix that quickly and cheaply.My second issue is that the chain through bolts don't seem to be secured. Through bolting is no longer as popular as it was a couple of decades ago. More shackles...

Moisture can loosen the internal bonding on any partial based material. 12 days should cover that unless the humidity is Florida high.

Oh yes, There used to be accessory holders for bare PAR lamps. I mostly used the MR16 ones but they were made up to PAR38. Front and back halves screwed together to trap a lens or louver. They would be ideal with Roscos dicroics. A pricy but permanent option, but maybe plastic discs and gel?

Almost anything paint, dip, pen, wrap can change the lights color. But several issues will come up.I'm sure you've thought of most of these, but here is what comes to mind. Safety first of course. Even just flakes pealing off the lamp will trigger nasty audience reactions. LEDs are cool-ish...

I'm curious, how long did you let the primer dry?

I have no personal connection or even work in that area of the industry. Yet I find such a collosal safety failure quite upsetting.My mind boggels trying to imagine how those closer might feel. Condolences to the survivors!

One bad connection can damage a surface enough to cause all other connections to overheat. Thus the multiple dark spots.Oh yes, such added resistance (in series) actually reduces the likelihood of the OCP from tripping. Higher resistance means lower current, as voltage is external.

I recall seeing (some decades ago) receptacles from a major manufacturer that had a "Top" label. That made me dead certain (for a few years) that there was a 'correct' direction.I am fairly sure that the similarity to a face can cause some people deeply unsettling feelings. Logic or even...

The breakers might still pop. Time for the 80% rule.Most breakers and fuses are rated for short term use, officially under 3 hours. Heat can build up in a system over time and get you back into trouble. For continuous use the rating is 80% of of full. Add to that aging breakers will trip...

Someone let the magic smoke out. SCRs are hard too diagnose visually.

I've recently heard of 2 systems going down due to failed UPS. Congrats on planning ahead!Before anything, I would make sure that ALL the configurations are written down, backed up, and sent to ETC. Then I'd call those real experts and ask them about it.Do you have correct diagrams of the...

There is DMX capable microphone cable. It should say something like "RS-485 rated" on the jacket.I suggest you make a written list of safety issues and functional issues. Try not to make broad statements of danger, but state what you see. Note where the problems are simply not up to industry...

There a minor issue with lamp cord in theaters. The National Electrical Code section on theaters has some rules to follow that limit lamp cord. (NFPA 70 520 Part V) I leave it to you as a learning opportunity to find and read that section for yourself, or with your teachers. "Hard usage" and...

Permanent construction in a public building for a private company, even a school, is fraught with issues. I'd look into renting, as your long term solution is in process.
