We installed an ABB disconnect switch 200A inside our control panel (for HVAC unit).
The unit was inspected and the inspector ask us to protect the incomming line lugs.
Since the disconnect is inside the control panel and we need a tool (hexagonal key) to open the control panel, I thought that we didn't need an additionnal protection.
From the article 110.27 A 1(1), I think that I don't need to add guard on the lugs.
Is there another article that I do not comply?
Thanks
