How do you calculate the total voltage drop for a circuit with multiple parallel branches?
TOTAL VOLTAGE DROP FOR A CIRCUIT WITH MULTIPLE PARALLEL BRANCHES

If they are truly parallel (connected at the source and load), and the wires are installed in the exact same manner (same length, same conduits and configuration, same routing, same wire types and sizes.....) then the current divides evenly between the branches, so the voltage drop can be divided by the number of wires.
Or you can divide the current by the number of wires. For example, 1000 amps on 4 parallel sets of wire would be 250 amps per wire. So use 250 amps and a single run of wire to figure the voltage drop.

I though he was talking about wires being in parallel.
One thing for sure - the original question "multiple parallel branches" doesn't provide enough info. for us to do anything except guess, no matter how many times someone asks.
