3 Phase switch board connect to switch?

"3 Phase switch board connect to switch" OK, this seems to be asking something about 3-phase electricity... "switch board " seems to be asking about a "switchboard", but that is an item normally used on telephone systems, not with 3-phase supplies or appliances. "switchboard connect to switch" makes no sense at all. Something is missing from this question! So this question does not make sense. Whoever asked this question should please log in and edit this question so that it makes sense.

Then someone else may be able to give you an answer.
