In Reply to: RE: Oyaide Black Mamba-Sigma V2 Power Cord posted by smart845 on December 24, 2016 at 04:57:15
My experience of a solid core conductor for a power cord build has been unsatisfactory. I prefer a stranded conductor so I can't offer an opinion of the EE FS 2.0 V2. I have two more DIY Oyaide Black Mamba V2 power cords to build with different AC connectors so I'll have an even better idea of how good the bulk power cord is. So far, the performance of both the Sigma model and bulk power cable product is excellent, to my ear.

when doing a black mamba diy power cord, what do you do with the drain wire and copper sheath? are they attached to the ac connectors?
thanks,

By default, the drain wire should be connected only to the ground prong of the AC plug, and left floated at the IEC connector. However, you can experiment by doing the opposite if you wish, since there is no hard rule in this matter. In my case, I choose to use the default method for the Oyaide Black Mamba V2 power cord without experimentation.
You addressed the drain wire, but how do you handle the copper sheath? Just leave it be? Thanks.I think understand. The ground is connected to the ground prong on both ends of the connectors, but the drain wire to only to one ground end of the connector, at the wall connector.

Yes, the ground conductor of the power cord is connected at both ends of the power cord, but the drain wire is only connected to the AC plug, not the IEC connector.
The purpose of the drain wire is to make contact with the copper foil shield along the entire length of the cable. The copper foil shield should be cut back to the end of the cable jacket at both ends so it is not exposed. The drain wire should also be cut back at the IEC connector end of the cable jacket so that it's not exposed. Only the drain wire at the AC plug end of the cable should be exposed in order to connect it to the ground slot of the AC plug.
Thank you much!
thanks duster
Many thanks Duster for your insight.
Just to clarify this cable will be two 24ft spurs from breaker to Oyaide R1s.
I think I will try the Mamba this time around over the EE FS. On your recommendation.
Merry Xmas
