Great explanation and will presented. Thank you for making the world a better safer place.

Thanks. If you ever want to make a video covering the details of a 87 differential relay, I'd watch the heck out of it.

Good one.. u need to do a video of how to calibrate it

[@kettch42]

Read the manual.

[@downhillskier8908]

.2 if it trips an auxiliary device, 2 if it trips a breaker directly.

[@jayschumacher815]

What is with the .2 or 2 amp tap selection?

[@williamruhling2729]

That is for the seal-in unit. It is based off of how much expected current will be going through the trip circuit.
