From time to time I look around and see posts that sometimes appear to be unanswered to the level that i feel the OP leaves with the proper understanding of what the experts response is conveying.
First and foremost…Robert is 100% correct and I have come to expect nothing less that perfection from him. The concern for me is the OP (Sam’s) followup response.
Now the question and image. While I must admit and as most of you know my eyes are not what they used to be in terms of looking at online images (Diabetes…sorry(. However, what concerns me is the statement below.
If this is the case you would have a floating grounded (neutral bus) that is connected via the green wire to the grounding bus and no mention of this panel having the equipment grounding terminal bus directly connected to the enclosure. You essentially have two floating bus assemblies with none connected to the metal cabinet…
While we all understand (hopefully after over 10 years of my harping about it on this forum) that the grounded (neutral) bus has to be isolated from contact the metal enclosure, you may refer to it as “floating” if you wish. However, the bus with the EGC’s (Equipment Grounding Conductors) has to be directly connected to the metal cabinet for any OCPD to function properly.
Again I may be missing it in this image and the OP never actually replied accurately back to Robert’s important question. If the response is accurate in the OP’s follow-up response in post 3…then you have a huge issue on your hands.
So I am hoping Sam ended up getting this correct in the end. Also if the images show something I am not seeing remember I am going off of the actual responses to formulate my worries in regards to the this installation.
