Recommendations for 20 amp electrical outlets

@jea48 no I ordered the Hubble 5362. No replying needed. 

(FYI you will not wire the IG, Isolated Ground, outlet as an IG outlet to your existing branch circuit wiring. I assume your branch circuit wiring is three wire. Hot, neutral, and EGC). EGC, Equipment Grounding Conductor.

@jea48 , sorry that due to my limited understanding  I have to ask, but what do you mean by this?  If I bought these outlets (either the Levitons or Hubbles) . wouldn't I simply replace the existing outlets that I bought from Lowes by connecting the existing black, white, and equipment ground wires to the Hubble or Leviton outlets that I bought?  Am I misunderstanding this?

As a proposal to be looked at for the Termination of the Audio Systems Devices and cutting down on the Quota of Wall Sockets to be considered. The Link will introduce a Device to be used, that when shown as a Link in another Thread has been made not to meet USA Code.

The Device has Pure Copper Contacts and can be produced to be the Termination point for all Devices Cables prior to the Wall Socket being utilised.

I also recollect designs from Wago that are Wall Mounted as the Wall Socket?

I know individuals using Wago Termination, where the rep[orts offered on usage, are ones where the user is extremely pleased with the impression it has made. Expensive Wall Sockets that were Superseded by the Wago Option, were not detected to have been Outperformed when the Wago Method was introduced, noe was the Wago Methos detected to have been lesser in its performance. The tidying up of the Cable Termination End is also claimed to be a satisfaction.

Additionally, When taking the Power Supply to a Audio Device as a serious consideration, it is always worthwhile looking into the option of have the Devices Power Chord bypass a IEC Connector on the device and have the Power Chord attached as a Hard Wired design. This as design if utilised  removes the need to be considering using an improved metal as the contacts on a uprated IEC that might be considered to be retro fitted. This as a Method is regularly seen to be reported on as having a Impact that is a Betterment.

If interested in the Hard Wired Power Chord as a method, the use of the Power Chord in the Link, which is offered for very fair monies. Can be used as a Cable for an investigation. From what I know today, this Cable  has the potential to make a impression not thought achievable for such a Outlay of Money.

The Cable has Superseded  the use of both Furutech and Nanotec Cables using PC Triple C Wire.

I had 2 20 amp circuits put in 15 years ago. Best investment I ever made. The gift that keeps on giving!
