The video below has a contractor walking through tips on pulling electrical wire — useful whether you're running building wire, communication cable, or shop-floor tray cable. The walkthrough shows several cable types side by side, including Ramcorp's tray cable shop products. One thing worth flagging if you're pulling a mix: smaller-gauge cables (18/2, 18/4, 16/2, 14/2 — the kinds you'd find in fire-alarm, control, and plenum runs) are far easier to over-stress than 12/2 building wire. The thinner conductors stretch first, the lighter jackets scuff or crack, and the damage often isn't visible from the outside. ICEA recommends a maximum pulling tension of 0.008 lbf per circular mil for copper conductors as a starting point — if you're at the limit, step up the conduit size, add cable lube on the long sections, or split the pull. Most pull failures aren't dramatic snaps; they're cracked jackets and stretched shields that pass install inspection and fail months later. The full plenum-cable lineup is at ramcorpwire.com.
