Correct way to wire a duplex?
 

Hi there,

I installed last week two Shunyata CopperCONN and it works extremely well. Still, I wonder if I had them correctly wired. What I actually did was to wire the two white wire under the same silver screw, and the two black wire under the same gold screw. While browsing the forum, I found some pictures of how to pigtail the SR-Z1 duplexes. There is this jumper wire that I wonder if I should install on my CopperCONN and move each wire under the second screw as pictured. Any though?

Yes, connect it exactly as shown. The jumper ensures that the current does not run through the thin jumper that connects outlet A to outlet B. And connecting the hot and neutral to opposite outlet contacts balances the current flow between both outlets.

Thank you Caelin, much appreciated. According to the pigtailing techniques shown and my actual electrical installation, I came up with this wiring sketch. I know it's not perfect to only have one dedicated line for 3 duplexes but silly me I only installed one when the walls were completely openned. I guess a power conditionner will help also in that area.

Why the jumper and link? Is that to protect against extra thick maple syrup? (Just a Canadian joke. No insult or slight intended)

I'm not an electrician so I don't know. But I'd be more worried about the screw camping holding 2 wires vs the current carrying capability of that metallic strip. Plus I'm not a fan of multi path for the current. Like wearing a belt and suspenders.

Just so you know, there are four different grades of maple syrup, from clear to thick ;-)

You may have missed it but Caelin in post #2 confirmed why it is best to wire with a jumper.

Your on the right track but not quite correct. Think about whst you did in the pictures. What are you told about grounding? Apply the same philosophy to the hot and neutral.

I just received my CopperCONN duplex yesterday. I plan to plug a Sigma XC power cable which feeds a Denali v2 into one outlet and an Apple laptop wall wart power plug into the other outlet. Since the Denali will draw a LOT more current (i.e. my entire audio system) than the laptop should I not worry about adding the two jumpers wires which did not come with the duplex to it? It wouldn’t seem it is necessary due to the current draw differences but I am not an electrician. Thanks for any advice you can provide me.
