Since zinc is, to coin a phrase, a
"least metal", adding sacrificial zincs means the current flows to and
erodes them rather than some valuable and essential component of the vessel.
I assume, therefore, that the recommendation to "unplug" simply removes a
possible source of accelerated deterioration.
