Why do they do this?

I think its a good idea to leave a few wraps. But the picture Hal posted is a bit much. That control could be replace 200 times without running out of wire

Klein still makes a BSP screwdriver with a extra pin offset in the bottom of handle to support 18- 24 AWG when you curled wires.

Dunno about that. Is that the Klein 603-4B? From the description it sounds like it's made for us:

• Metal stud offers a convenient and easy way to bend, loop and connect solid wire when installing outlets and switches
• Bends 10, 12 and 14 AWG wire

If the curls were a Bell requirement the only way is to find it is in the Practices. I have never seen them in their entirety and wouldn't know where to find them now or where to look if I did have them. It's several large binders that are not an indexed .pdf.

For us electricians, it was ever only a doorbell trick. So when the cable was destroyed, you would always have a bit more in the wall if needed... we started using 3/4" pvc for a little stucco chase at the door bell. And just used the pipe...
Who knows..
