So I came across something today in the field and I cannot wrap my head around it.. Hopefully someone can help.. They call it a 2 wire drop.. It involves a 2 wire (H,N,G), and two 3 wire (H,H,N,G) coming into a box. The box will hold a receptical that the top is on a switch and the bottom stays hot. The part that confuses me. Is they had the neutral (I believe, Or it might have been the other way around) tied in with the hots (black).. Apparently, this will bring power to the switch and back to the box? I need to know how it works and why.. Thank you guys for bearing with me..
