HVAC and Generator tech here plus lots of electrician work without the title... lots of AC and DC troubleshooting and lots of power generation work.
Fluke 87 and a 600amp clamp is what I'm supposed to have.
I have the Fluke 87V and Fluke 376 clamp meter with an iflex 2500A flexible bundle clamp as my "Main meters". I rarely use either of them unless I'm doing critical grid work, or need to see multiple sets of inrushs. the current clamp is big and only gets used for checking amperage on units running in parallel since it has the flexible whoseyourdady to go around 5-7 pieces of 4/0 cable at one.
I use a basic electricians fluke set with a 332 clamp and 116 or 117 the most. both fit in one case, small and compact and will do 90% of what most people will ever need, and then some. both meters, in a soft case with two sets of leads, and a temp probe is 350-400new. scored this one new in box at a pawn shop for 200 and its served me well the last 4 or 5 years. just as accurate as the 87V.
I also have a T5-600 that gets used mainly for the current clamp because its an open end, narrow current clamp and is excellent for taking readings inside of control panels, pump panels, etc. but the max wire size is about #2 wire. I rarely use it as a "DMM" unless I'm at a festival/concert type job where there are a ton of food and electronic power needs. it fits in your back pocket, or even cargo pocket with ease.
leads need to be checked with your meter... leads can leak once the rubber breaks down. I've seen enough mishaps from old beat up leads to not trust anyones but my own. you don't need leads bleeding out voltage inside of switchgear! My meters are calibrated every year and leads changed every two, unless something happens to them, then sooner.
