Let’s start off with I’m cheep and cantankerous. That said, quality can be much cheeper than buying cheep. Last week I was clamping some loads for a generator proposal and my Fluke 80i-410 gave up the ghost. I had paid about $500 for it 30+ years ago. I think I got my money out of it. No local supply house had one in stock so I ended up buying “the best” Klein that HD had to offer. I would have rather bout another fluke but I needed it for the days work. Maybe I’ll buy me a better one and issue that one to one of my guys. I digress.

I’m about 85% confident that I’m getting this generator job. I’m gong to be putting 250’ of 480V 500KCML underground and if it ever was a good idea to have a megger, this would be it. I’m probably getting a few more gen jobs from this customer too. It makes sense to buy rather than to rent So long as I can get sufficient quality for a price I can stomach. I remember that once upon a time, a MIT310 was considered a good megger. The eBay prices for a good condition used one are right in my wheelhouse. Would that be a sufficient piece of equipment?
 
I know nothing about the MIT310.
My Flukes were less than $400 new from one of my CED supply houses. I bought one for each of my service trucks. Small shop so only three of them, but we could be 100 miles from the guy that had it. I’d buy them again at whatever price they are today.
 
Fluke makes a combo DVM and Insulation tester. It was too easy to use so for a while I would check with the good old hand crank megger. Eventually the megger went on the shelf
 
Well, I got a megger. No idea what it is, I’m picking it up next week. A buddy of mine called me up and said that he bought a megger for me at auction and that I owe him $200. Once I grab it, I’ll post up some photos and you guys can tell me how I did.
 
Before I retired used a great Fluke model 1577 combination insulation ( megger ) multimeter. Used it trouble free almost everyday for over ten years. We had over 500 VFD'S & bucket starters that had to be PM'ed 1 to 4 times a year. Best thing it cut carrying a VOM & a megger to just one meter. Like to have a dollar for every time that I dropped it off a 6' ladder. We had two big Greenlee meggers in our shop and did not like them. That megger puts out think it was 5 different DC test voltages with the highest being 1,000 volts so that was ideal for meggering 480 volt motors.
