While exploring I found couple of Junction Box/Electrical Distribution Box with cool Art placed on it, For reference I am sharing a street view image of one of the boxes as I don’t want to share the photo I have taken,
Although the boxes are common but couple of them have cool art drawn on it, But however I am not sure if this is an eligible POI due to it being a electrical distribution box.
The art is the point of interest, so make that the focus of the nomination. Anything you can find out about the artist or title of the work can help.
A plain box would not meet criteria. However, I don’t think it would be an unsafe location unless behind fencing with “Keep Out” warnings, if that was your concern.
The art is suitable provided it doesn’t meet any rejection criteria, such as private property or not being publicly accessible. In general, being on a junction box should not cause any additional issues (there may of course be specific junction boxes that are a problem).
