Twisted-pair wires to reduce surges [RE-wrenches]

[Todd Cory, Mt. Shasta Energy Services]

As I understand it with AC the twists help the emf to cancel each other out.
It also helps prevent induction for the same reason.

Also to twist wires fast and easy, anchor the wires at one end, insert a
bent U shaped nail in your drill chuck, attach the other end of the wires to
be twisted and press the trigger... fast and easy!
