I am using Furutech
FI-11(Cu) plugs/iecs.
The Furutech connectors clamp the wires in a way that allows two wires to be clamped at the same time. The screw that tightens the clamp is located in the middle of the opening for the wires. I believe this allows the use of spades to be tightened by the clamp but it also allows either the strands of a single wire to be split in halves which each half twisted like a forked snake tongue, or for two separate wires to be used. IME, the 10 awg WE wire just fits on each side, so I have used two 10 awg wires per pole, plus two for the ground. Good thing the WE wire is so flexible because terminating that is a bear. Check the link below and scroll down to see the picture of the back of the plug, where the wires go in. All of their models terminate similarly.

I liked the idea of using two 10 awg wires per pole for my two big amplifiers, and I made a similar cord to power my Isoclean conditioner that powers all my front-end digital stuff. From the conditioner to the individual digital gear (i.e., server, dac, power supply, etc.), and for preamps, the twisted pair of 10 awg wires is plenty big.
