I know that normal practice when installing a whole house DPDT generator transfer switch, which sits between the meter and the main panel, is that the switch box is now the service entrance, hence the main panel is then a subpanel and the grounds and neutrals need to be separated. (This can be an easy, or messy job if the original installer didn't use separate busses for grounds and neutrals). What I am having trouble locating is exceptions to this rule, if any. If the transfer switch (SE) panel is located immediately next to the main panel, and they are bolted together, and the pass through for the cables is a single shank connector with nuts on both ends, then is it legal to run just the two SE wires and ground from panel to panel and leave the original service entrance panel as it was.
Since the purpose of floating neutrals in subpanels is to prevent multiple return paths, it is hard for me to see where such a path might exist in the instrallation I described.
Any insight, or code references?
