I live in Wales and our rules say unless the is a safety issue motors must not auto restart when power is returned after a power cut.
Most of our starters automatically do this be it direct on line, star/delta, Auto transformer, resistor, inverter, or soft start. There are cases where motors have a simple switch and the cheap method is to use an active RCD (GFCI) which auto drops out with a power cut.
However is seems the term NVR is swapped with DOL in some USA Utube videos and out of interest I wonder what you consider is NVR?
I just wonder if it is what we consider as anti-single phase device as in the UK the term NVR is hardly used yet is seems to be used a lot in USA.
Remember I am an electrical engineer so I do know standard systems but it's the language between USA and UK which causes my problem. We all both sides of the pond use words incorrectly so not looking at technical but what it often refers to.
When in UK we say we are going to get a DVD we mean buy or rent a film even though a DVD has many other uses. So what to NVR mean in USA?
