JR23 Combo Regulator and Neutral Tester. To verify it is on Neutral before you energize it.

As I explain to people how to use the JR23 tester. The comments I hear are, we use the three switch by passes. And energize the regulator from the load only. Check n lite and use RND tool. This is great except you could still have an open  lead in the regulator. And have a catastrophic failure when you energize. The JR23 will test, to make sure you don't have an open  lead. Before you energize. It is also A REGULATOR TESTER.

One day on site regulator school. If interested please register. Then will get dates and scheduling set up.

FEE $1500.00 includes travel and expenses.
