Wait, is this a trick question about red black blue versus black red blue?

Or, is it actually 277/480 and the guy just used went with:

No tricks here. Well kind of, that's why it's a trivia. The winner wins...absolutely nothing!

Does the lack of a ground conductor come into play at all? Is this whole setup actually part of a 120VAC grow room in somebody's basement? Are three-way switches involved? Did an alien wire it? I need hints, eh

Given the picture there is zero.zero requirement per code to involve a green wire in the mix.

Yep, R.I. Fire alarm. The red and black were a dead give away because they were twisted. They are the SLC. The Blue and White are NAC wires. That is probably a horn/strobe box.
What do you mean I win nothing?

Well, it was supposed to be, but the EC cheated and blanked it off and used wire nuts which aren't allowed under the RI fire alarm code. I shoved those off to the side to take the pic. Oh well, there's another horn strobe in the room and I'm not fixing the wire nut splices.

Meh. I don't work in RI for the most part. Only FA splices I have ever made with terminal strips is when I am repairing Protectowire. I guess all the buildings I have installed or repaired the fire alarms in are going to burn down because of all the wirenuts and red jacket cable I've used
It's all about $afety

Yes. You can take two identical commercial office or similar buildings on the Mass/RI border in eye shot of each other. One is wired to the RI Fire Alarm code, the other is wired with exposed low energy cable and splices everywhere. The building in Mass. probably also is wired with NM cable above the suspended ceiling because it's still allowed. Tell me, is the building in Mass. any less safe? They could be 500 feet apart but one is considered "unsafe" by these stupid RI rules.

Lemee guess, the Blue wire is the positive 24 volts and the white wire is the negative.

Muttering to myself,....Weird assed electricians
