It looks like a lot of panels we've built here in NZ, we call it electric orange haha. We also use RWB for our phase colours. I've never seen Japanese panels tho so I'm not sure
Why are all the wires for the cts and the voltage taps sheathed in an outer clear layer?
Also, what are the black and orange ct looking devices on the right? My thoughts was some form of RCD but the multiple taps off, plus the ground connections have me confused.
We use a 10 core cable for the voltage references and CT cables, and we run it in clear tubing as Australian standards requires all electricity distributor metering cables in that section to be double insulated.
Those are bar mount CTs, they just have orange covers for the terminals, kinda like this. The earth is looped on the S2 terminal of each to keep them referenced to ground.
This wouldn’t fly in Queensland - right hand CT’s shouldn’t be in the metering cubical, phase colours on CT’s not correct, not enough insulation on bus, cubical looks too small. PVC sheeth is a funny touch too…
Is this in Japan?
It’s in Aus mate!
Brilliant work sir!
Looks like Aus or NZ to me
You think? I ask because I've seen Japanese panels that were this shade of orange and the color code was red-white-blue.

We call it X-15 orange but have heard electric orange too
They do this orange for stuff in South America too believe it or not. Saw a lot of it in Brazil.
Extra insulation on those current transformer leads? I suppose they are technically low voltage signal wires so it makes sense.

What state?
Is this a ct chamber for an energy provider?
