Let me go ahead and talk about these two patterns in front of you. If you notice, the one says amps and the other says volts.If you’re going do an amp check, you need to put an amp probe on. Now a couple of things I want to point out real quickly here.

There’s been a lot of news on this. There’s been some big changes. You may be aware of some of them. Maybe not aware of some.
