I need to pull a new wire through conduit that already has 3 wires. Ive pulled even heavier gauge before, which wasn't too fun, but this is my first pulling with OTHER wires already in.
All wire is stranded. I need to pull (1) #10 THHN thru underground 3/4" conduit that already has (3) #10 THHN for about 60 feet with two 90 deg bends.
What approach should I take?
Should I dig up the two 90 deg bends that are underground or will it take the corners ok? Is lube unnecessary? Should I pull the new wire (and a string) using an already installed wire and then pull old wire back in with string? Will fish tape have problem passing the 3 already installed wires?
What would you pros do?
