Bought this on Ebay and it was advertised as 600 A, arrived today and its 400A

Amprobe ACD-14 PLUS TRMS Dual Display Digital Clamp Multimeter 600A **
I think most situations 400A is plenty, if I do industrial I will need the 600A tool.
I can send it back but why bother as all I do right now is residential.
Save that one for the residential jobs or return it. Some of the industrial inspections I’ve are in the 2000A range. Of course I’m not the one taking the readings, but they do often use my meter.
I bought it because why not keep getting better as an inspector? At the least I can tell if the phases on the feeders are pulling the same amount of current.
As Chuck says others will do the measuring in industrial but in a residential setting I’m not likely to see more than a 400 amp service, had one a few months ago and on 6000SF homes they are common.
On returning it, I only paid $50 for it and if it will do residential I’m satisfied. I like calling an electrician if theres a problem but simple testing in a residential property I’m good with.
I’m not qualified to do industrial so thats not a concern right now.
Didn’t say I would put it in a report.
Just said I could test with it.
I am a new thermographer, Level 1 which means I don’t know very much. I am starting Level 2 which is difficult for me to grasp right now but it is more about quantitative reporting which in my understanding means after you do a thermal scan and find an anomaly2 you might need other test equipment to determine what your problem is.
Feeder cables could be checked for balance and loading.
Also I couldd check the nuetral for overloading.
Like I said I’m new at this and looking to be a more educated inspector, give me some time and I will be.
Can you think of a circumstance would cause a grounded conductor to be overloaded on a branch circuit? On a feeder? Do you know the relationship between the current load on the ungrounded conductors and grounded conductors on a single phase system? These are things you want to know before you start going wild in a panel with your new toy and writing about unbalanced feeders in your reports.
I won’t be writing anything in a report anytime soon after using my new toy.
I already spent some time reading about how the clamo meter is used and what affects it.
Never claimed I was an electrician and I have no trouble admitting I am a student.
