Our training facilities along the banks of the beautiful Muskingum river, in southern Ohio.

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 or grounded 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 or grounded lead. Before you energize. It is also A REGULATOR TESTER.

Deadline Monday July 17th.
