    "Measure" as in measure in what way?

    Voltage? Current? Terminal torque? Size?

    Sounds like the power company needs to be called rather than you measuring anything.

    For voltage, any decent quality multi-meter will work.

    For current, any decent quality clamp-on ammeter will work.

    But unless you are actually measuring the voltage and current when there is a brown out, you will not know it or be able to determine if it happens or not.

    Besides, actual brown outs are power company problems, which would likely include, and may even be, related to or caused by the overhead service drop or underground service lateral being deteriorated.

    Are you having problems with the service TO the condo building, or from the condo service equipment to each condo?

    Les,

    It is really difficult to understand what you are saying with the terminology you are using, so far, up until the above, I *think* I've figured it out, but in the above ... ????

    A) "the problem seems to be at the service equipment to each condo to the hook up from the utility company"

    B) "also there are a few empty units and a couple were jumped wrong"

    C) "come to find out when they put the power back on it was jumped wrong"

    D) "and only one leg was getting power ...."

    What I think you are saying, but am not sure, is:
    A) The problem seems to be at the service equipment connection to the utility power AND at the service equipment to each condo?
    - If the problem is at the service equipment to the utility power, that same problem will show up down the line.

    B) "jumped wrong"?
    C) "jumped wrong"?
    - Do you mean the feeders between the condo unit panels and the service equipment? That there are two feeders and only one is 'hot'? Not sure what you mean by "jumped" much less "jumped wrong".

    D) Only one leg has power
    - Okay, and if that is also at the service equipment to the utility power, then there is no way to get that leg hot downstream to the condo panels. This would be a utility problem, a dropped leg.
    - Now, if the service equipment has power at both legs, but no power at ANY of the condo panels, then something happened to that one leg coming off the service equipment.
    - If the service equipment has power at both legs, and SOME condos have power at both legs but SOME condos only have power on one leg, then it may be that the service is 3-phase and on leg has been dropped, which would properly power all the condos on the two working legs but not any of the condos with one working leg and one dead leg.

    It would really help if you used proper terminology.

    Also, and I really hate to say this, but ... if you do not know the proper terminology then I think you quite possibly do not know enough to do what you are doing, especially not and charge for it, but even not to do it as you could screw something up really bad, which could injure or kill someone, which means you should have a knowledgeable, qualified, and licensed electrical contractor come out and go through it all and find the problems, with you "hanging out" with that electrical contractor and learning as much as you can. Sorry, but with what you are saying, I really think that would be best for you and for your client(s), both for your safety and their safety.

    Are you refering to the metered service equipment at a bank of meters for the condo building (where the services are) or the feeders to the individual condo unit panels?

    What is the reason behind your questions? Are you performing an inspection for a client?

    Les,
    You might have a pissed off late shift worker that comes home and goes to the panels and just flips the main breakers off and then back on for a thrill. I know that 100 years back, when I lived in an apartment, I had a guy below me that would leave his stereo blasting and leave his apartment. I just went out and flipped his main breaker.
