Electricians - who do this all the time - ALWAYS pull them together when they
can. This avoids the ADDED friction of each new cable against all the other
cables in the conduit.
You can roll all the cables out, forming a long, untwisted bundle, and aligning
it with the conduit. Tape the pull rope connection to the bundle to form a
smooth arrow-head-like transition, so it won't hang up on a coupling (NO
LUMPS). If the connectors are already installed, stagger them so no large lumps
are formed. Be sure that no tension in pulling is applied to your connectors by
taping the cables to each other near the ends before a final tape wrap over the
Then, keep the bundle aligned with the conduit as you pull cables through (a
second person can help here). Use "yellow Stuff" lubricant (or equal) along
the entire bundle if you have any doubts about friction. And, simultaneously,
pull another "haul line" with the wires, just in case. Leave it in the conduit.
Force a couple of Brillo pads around the cables at each end to keep vermin out.
