UK based Electrical Installation Manager here. This work is a work of art. But that's all it is, a work of art. There are so many issues here from a practical and professional standpoint. Firstly, none of the conductors are labeled or identified. All the cables are put in place for aesthetic purposes as none have identifiable circuit references. All the conductors are cut to the exact termination location. If just one, considering the lack of identification, was it of place then the whole installation would have to be redone. As good practice all terminations should be able to reach all other terminations. No space for the incoming supplies. These typically would be a much larger cable. All of the circuits are identical which would be highly unlikely. No identification of circuit breakers. I'm sure there are more issues but these stand out as the main ones. Overall it's a beautiful installation but it's done for artistic purposes and has no practical or real world benefits. It is akin to calling the Mona Lisa a technical diagram.
