Trying to add an outlet to an existing circuit

i am putting a tv in an old closet so there is no outlet on that wall. I decided to add one. I have wired a new outlet in series with an existing outlet circuit in the room. I have 120VAC on the outlet but when I begin to plug stuff in the power strip will start cycling power. I have tried different power strips and they all do the same thing. I then plugged the power strip into an outlet on the same circuit after my new outlet and everything works fine when I plug them in.

What did I do wrong to this new outlet? If it is in series and stuff down stream from it works then I do not see why this outlet does not. I have tried two different brand new outlets and they are both do the same thing.

I am using a plastic gang box but I do not see why that would be an issue. I have the grounds landed on the ground screw on the new outlet.

Anyone have any suggestions? Thanks.

 

I don't know, but have you tested it with a receptacle tester to see if it is wired correctly?

More information might help:

Can you explain what you mean by "in series?" Receptacles aren't wired in series, they're wired in parallel.

You ran cable from an existing receptecle to your new receptacle, and then from your new receptacle to a different existing receptacle? That's how you wound up with receptacles both upstream and downstream from the new one?

 

Receptacles are wire parallel not series.

What does "cycling power" mean?

Good but grounds have nothing to do with the basic function of the receptacle.

 

Series was the wrong word to use. I basically put an outlet between two other existing outlets. I ran a 2 wire Romex from each existing outlet and landed them both on the new outlet.

I think I may have figured out my problem. The house is not wired like I thought it was. I am going to have to find another place to tap into the circuit.

Thank you all for your responses.

 

If everything else is working now, won't simply removing one of the two wires you ran correct the problem?
