Wire the POS, so learn what brand is being used in each install you do, and DO THE LV WIRING! As you learn different POS brands, you get better at it.
I assume you're referring to Point of Sale when you say POS and not something else with those initials!
Depending on the location and the union, he may not be allowed to do the LV wiring. Just the hookup, commissioning and programming.
