I agree that more information is needed. Specifically, is the "electrical equipment" that has plumbing pipes above it on the list of items that require dedicated space? That is, are we talking about switchgear, switchboards, panelboards, or motor control centers? If not, then there is no issue with pipes above the equipment. But if a pipe is installed above one of those items, it must be at least six feet higher than the top of the equipment, and there must be a drip shield between them.
Please clarify the installation.
