Spade connectors from Romex to outlet?

No doubt: The best way to go is with the Hubbel Hospital Grade outlet. Higher amperage rating and tighter grip on your plug's prongs. Plus the push-in wire connection. If you're stuck on spades and solder: Use a standard flux-cored solder, and clean all the residue off with a solvent after soldering. The spades are super easy to trim, so there'd be nothing hanging out.

Hi Keith, I've done alot of experimenting with dedicated power over the past year or two. 10 gauge AWG is very hard to work with, especially if you are installing the 10 gauge under the neutral and hot screws on the sides of the duplex outlet. It can be done, but it takes alot of time and effort. What I've found is that I preferred the stab in connections on the back of the duplex outlet. With my system the sound was more open and faster with the "stab insertion" method, compared to the "under screw" method. I would not use a spade on your Romex leads. First, adding any extra connectors gives you a lose of power transfer--(or signal transfer, interconnects for example). Second, if you have any bare connection sticking out from the duplex outlet, you run the risk of shorting out the duplex socket if the bare Romex grounding wire touches your bare neutral or hot. I'm using an Isoclean 002j duplex outlet for my sources and three Wattgate 381gold duplex outlet's for my preamp and monoblock amps. Your mileage may vary, but I've tried multiple configurations over the last couple years and this method is what has worked best for my system. Best regards, Stan

Thanks you guys for your input. Ya, I'm going to go with the wire in the back of the outlet. Like I said in an earlier post - I didn't realize that the push in connection on the back is a clamp down set up. That'll work just fine.
Thanks to all for responding.
