Electrical β FAQ
Can I use a steel fish tape in live conduit?
Never. Steel conducts electricity and creates lethal shock hazard. Only use non-conductive polymer tapes when working near energized circuits. Always verify power is off before fishing with steel.
How do I prevent my fish tape from kinking?
Keep the tape straight during rewind, avoid sharp bends beyond the tape's rating, and store it in its case when not in use. Inspect the leader for nicks that catch on conduit seams.
What's the difference between flat and round fish tape?
Flat tape provides better push strength and often includes measurement markings. Round tape navigates tight bends more easily and typically offers longer reach. Choose flat for precision, round for flexibility.
Why does my fish tape keep getting stuck?
Likely causes: damaged leader catching on conduit joints, pulling too many wires for the tape strength, or existing wires creating a bottleneck. Try pulling back slightly, then pushing forward while twisting.
How often should I replace my fish tape?
Replace steel tape when you spot rust, kinks, or permanent bends. Polymer tape needs replacement when the surface becomes rough or the leader cracks. Professional use typically requires replacement every 12-18 months.
Can I fish through conduit with existing wires?
Yes, but use a swiveling leader to prevent twist. Apply wire pulling lubricant and pull slowly. For crowded conduit, use a stiffer tape and consider removing some wires temporarily to reduce friction.
