LV breaker testing with MAC-21 test set

Anyone here know if theres any guides or trainnings how to use the MAC-21 for breaker testing?

There is a manual that’s included with the MAC-21 that covers some basic information. If you don’t have that, I was able to find a manual for ETI’s tools (PI-6000, PI-800, PI-1600…) with the MAC-21. While your tool may not be an ETI tool, the general operation of the MAC-21 is the same regardless of the tool it is installed on.

If you have specific questions DM me and I can offer some help.
