 Power to VSRs is disrupted by cutting the ground wire. One way to reestablish the ground (thereby turning the device on) is HVD --> relay NO contacts --> ground wire in/out
-===== disconnecting voltage sensing relays =====
+===== solid state isolators =====
-These usually have 3 lugs:  starting+ in, house+ out, starting-.  The starting- "ground" is only used to complete a small circuit so the relay can run itself.  So it's usually very thin.
+Some solid state isolators have a trigger or exciter input;  drive with HVD as with relays isolators and relays.
+Three lug isolators without exciter input might not be usable with HVD.
