Hello to all. I am new here. I came here in the hopes someone can give me some help. I work on Modular Trailers like office, sales and classroom trailers. I normally do not mess with any of the utilities although sometimes I do some of the plumbing. But I will be the first to admit that I dont know much about the electric. I am sure i will get the "have an electrician do it" answer. I am trying to do that but it does not look good. I have a rush job of a smaller classroom trailer that I have to remove on Monday. And that means that if I cannot find an electrician on such short notice, cause I just got the job an hour ago, I will have to disconnect the power myself.
So, what I want to know is how I can test the main service line that comes into the breaker panel. I will go inside the building that they pulled the power from which is the main school building and make sure the breaker is turned off at the sub panel or however they wired it. But I still do not want to touch it unless I can test the wires right where they are wired to the panel before I would disconnect them. A friend of mine said he asked a friend that knows about electrical that said if I use a multimeter on AC Volts I can check it. But I am just not sure a multimeter can handle that kind of power. I am guessing it is at most a 100 amp service.
So, your thoughts please and if I have to go purchase something to do this correctly on my own, please let me know. i would rather ask this here than go to a lowes or home depot and ask them. Just trust it asking here much more.
Thanks

I don't know what you think a multimeter is but it can measure/handle the voltage just fine. That's if it is a good meter with a Cat rating.

But you really need to know how to use one safely so I would recommend at least getting someone that can use a meter to check it for you.
