A foreman told me my wire pulls were too fast and it was hurting the insulation
He pulled me aside on a big apartment job in Tempe and said, "Slow down, you're cooking the jacket." I was pulling 4/0 THHN through a 2-inch conduit and thought speed was key. Now I set a timer for five minutes per hundred feet and check the wire by hand for heat. How do you judge the right speed on a long pull?

Just keep a hand on the conduit to feel for warmth as you go.

Keep a hand on the conduit" is a good start, but what about pulls where you can't reach the whole run? Do you just rely on a helper down the line to yell if it gets warm?
