In a wiring diagram, T1-T3 stands for?

Explanation:
In wiring diagrams, the prefix T is used for terminal points on a terminal block. Seeing T1-T3 means you’re dealing with three terminals labeled 1, 2, and 3. So it reads as terminals 1 through 3. This makes sense because the diagram is pointing to connection points where conductors terminate, not to lines or measurements. The other options don’t fit because lines would be indicated with a different prefix, a set of letters would imply A-C, and pounds per hour is a flow rate unit unrelated to terminal designation.
