Looking to get some feedback if anyone has used the newer Megger SPI 4000 and or the SPI 500 for primary injection on LV Circuit breakers. My shop has an ETI PI-6000 (bitch to move around the city) an ETI PI-1600 ( which likes to sit in the shop and break out in the field) and 2 Megger SPI225’s I’ve started looking at possibly getting a Megger CB-845 to free up the 1600 but I figured id explore all options if its worth it.

The only Megger PI unit have experience with an SPI225 and that thing is very glitchy and will ruin your day if you don’t PDF your test sheet when your done.

Are the new units worth there salt? is it just a bigger glitchier version of the 225?

We ended up renting one a couple months ago. It is not a terrible test set, especially when brand new (Like the one we got). However its got a learning curve, and requires a computer to operate (No manual vernier like the ETI test sets). My biggest issue with it isnt how good it is (it feels great), its actually when shipping it to a job. If someone straps it in wrong, or the strap fails, I’m worried that the connections will break, rendering it a very expensive paper weight until repaired.

End of the day, put a tech who is quick to learn on it, and its just as efficient as the 6000, with less weight and less space, but without the durability imo.
