I'm designing some site lighting circuits, and need to perform a voltage drop calculation for the branch circuit wiring. When there is only one circuit "leg" the segmental voltage drop calcs are straightforward. However, when the circuit comes out of the panel, hits a junction box, and heads in two different directions, how do I calculate the total voltage drop for the circuit? If I'm remembering Ohm's Law correctly, the impedance of one leg factors into the resulting voltage drop on the other leg (i.e. parallel circuits). In the absence of Power System Analysis software like SKM, I'm struggling with how to accurately perform this calculation.
I guess the question could be further simplified by assuming two loads, one on each parallel leg of a branch circuit, rather than using multiple loads with long runs of cable in between. Say 100' from a source panel to a junction box, which then splits into two runs of 100' each to a load.
