Well, the newly installed EVSE switch may have paid for itself many times over just tonight.
We had a once in a "blue moon" loss of the neutral line today that took out the stove, coffee maker, two outside security lights,
one UPS and the garage door opener.
All the items that were on UPS units, on the solar system (off grid) or physically disconnected, including the new EVSE which
I had turned off earlier today were OK. That is not to say it could have survived, but everything that had a digital panel and was
connected is now toast.
Never underestimate the power (or lack therein) of a switch....
More later!
Open neutrals can cause a lot of damage. However, it's unlikely that your EVSE would be damaged because, AFAIK, most of them do not connect to the neutral as they are pure 240V devices. I know for a fact that my Blink is a 3-wire (hot1, hot2 and ground) installation.
The stove, assuming it is electric and 240V, probably still uses 120V for the control system and uses the neutral (or, if it is an old installation, shares neutral and ground on one wire).
