Hi,
Got some additional circuits to install as part of an extension. CU has recently been changed by another contractor to an amd3 unit, but cables enter cu through a couple of knockouts on the top with standard open grommets.
As it happens, the cables are so tightly packed in one you could probably argue that it meets ip4x....but is this really good enough?
I don't want to shoot the guy down if it's ok, but at the same time I'd rather run trunking to feed in my new circuits and chances are that customer will ask why have you done it this way when other guy did it that way!
