It's not a code issue, it's a 15 cent outlet issue. If you explore the local hardware store and look at the $5 and $10 duplex outlets you will see a major increase in build and material quality.
All the duplex outlets should be wired the same way if you plan on installing components into the same duplex outlet.

Thank you for your offer, I will ask Alan the next time he calls and see what he wants to do. Please email me with all the info.
On another note, the Reference One has sold out for the month of May, thank-you very much. We have a new batch of filters coming in early next week with a follow up order in the middle of the month.
I also have a couple PE V S/AC units still available at the introductory price is anyone is interested. Offer ends June 1.
