An automated function without an manual override function is a bad automatic function.
People always take the ease & convenience of automation for granted -- until they need control of the situation and can't take things manually.

Automation engineer here. If it doesn't have a physical emergency stop button, that actually cuts power in a way that can't be overridden except by physical wiring, I refuse to work on it.
No one who actually knows automation would implement it without a manual override indeed.

Machinist here this guy is right.. it's literally a textbook failure of design.

I mean you say that, but what if the manual override malfunctions and accidentally stops my murderous killbots? I would be so embarrassed.

All electrical circuits have "manual overrides" - it's called a circuit breaker. LOTO. Amazing to me that they don't have their lights on a dedicated circuit though.

What do you think every light gets its own circuit, or all lights go on one circuit

How many lighting circuits do you think an average sized building needs? Obviously not just one, but if they are using LED and HE fluorescent it shouldn't be more than a few especially if they are 277V. And they should all be at the same panel anyway.
If the lighting designer was a complete idiot and put 10 different circuits in 10 different panels that might be an issue, but most designers aren't that dumb.

Average size building 😂
You've never wired anything

Yeah see there are small sized schools, medium sized schools, and large schools. An AVERAGE means a typical building size. This school has 1000 students which is not big or small, it's an AVERAGE sized school.
I have done full electrical and low voltage design for schools, hospitals, businesses, apartments, etc. You don't know shit lol

Minnechaug is a large-ish school in terms of campus size. Definitely not the biggest around here, but larger than average. Sidenote: It's a beautiful school. Hope they fix their lights.

My definition of a large school is 2000+ which is common for high schools in my area. Elementary schools usually have ~500 and middle schools have 1000+.
A school of approx 1000 students, whatever you want to call it (big or average), is what I was basing my estimates off of.

Yeah if it’s 277v LEDS this building could probably be on 2 - 3 circuit breakers for lights easily

Ima blame a MechE because it's always fun to blame them.
