Voltage variations and Surge cut off.
We are hooked up to 50A service. I just recorded the voltages at different areas and I will note them below. I have a Progressive EMS/Surge suppressor hard wired in just before the breaker box. It has...

I shall also bring it to 132V to see if it plays any role in cutting the voltage or if it is merely for information purposes.
And how would you do that? :h To do this properly one needs some sort of variable voltage source (Variac) ... during my professional years I used one many times but now that I'm retired I no longer have access to one. In lieu of this the best I can do is use the EMS's input trim pot to reduce input voltage to the circuit board that senses and eventually triggers low voltage cutoff. However, that won't allow the voltage to be adjusted upward beyond what the source may be, say 120 vac ... ergo, the need for a Variac.
