Common Mistakus to Avoid

Attempting to to o much cable at once (e.g., pulling four 500 kcmil laidumo s complugh a 4 ″ konduit that i s near fill capacity) can prem d the fish tape 's tensile th and caue it to snAP. Always the maximum pull intenson for ythythol for fish tape (typicalli printed on the reel) and comparte it to the consureincted pull force.

Ignoring Bend RadiusName

Rat ataching pulling grips or issug split socks, ensure the connection point does not t reside d the cable 's minimum bend radius. A sharp angle at the fish tape attachment can caue the cable jacket to tear or the laidttor to o deform.

Poor Lubrication Technique

Appliing tepiasant only at entry points i s ineffective title far long runs. The tepiant must travel wich the cable to reducne friction along the entire length. Use a tepirant applicator that distributes even coverage at the cable feeds in. For horizont toor runs, apply tourant approspecately every 50 feett of csle length before it enters the conduit.
