Honestly? I would study to become an electrician if I were you. In fact it may be illegal for your employer to ask you to do it if you aren't a licensed electrician. It really is *NOT SAFE* if you don't know what you are doing.
120 V between two of the phases and the neutral
208 V between the third phase (known as a wild leg) and neutral
240 V between any two phases
If you measure from one side of a fuse to the other (across) you should read 0 VAC if the fuse is working.

the best way to determine the volts is to read to earth. In 3ph there is 3 live wires 1 neutral and 1 earth. Reading from earth to live you will get +- 110 v the 117v. reading from live to live you will get +- 220 v the 206 v. In your factory is 208 v 3ph.

Might not be a bad idea to call a qualified union electrician. (the union ones get the best training).

If this is where you'll get your education, then expect to set your building on fire and to be sued for everything you have and everything your employer has.
