In Reply to: changing electrical outlet---questions posted by silence on May 3, 2007 at 16:01:48:
AC outlets come with different methods of connecting the power wires (the ground wires are always connected with a screw terminal).As pkell44 observed, the cheap outlets used by most builders are "speedwire" to save electrician labor cost. They have holes in the back into which stripped wires are inserted. There will be small slots near the holes. To release the wire, you insert a narrow screwdriver blade into the slot and tug on the wire.
Outlets that are in a chain may have incoming and outgoing wires attached to these holes and use the small breakaway link between the two screws on each side to carry the current to the downstream outlets. If you encounter this, you should obtain short pieces of matching power wire and create pigtail connections with wire nuts joining the incoming, outgoing, and pigtail wires. Feed the outlet to the side screws from the pigtails. Do this with all the outlets in the chain, as even the ones downstream may make electrical noise from the poor speedwire contacts.
Some high quality outlets have holes in the back but are not speedwire. To attach the wires to these, you insert the stripped wires into the holes and tighten the side screws which engage mechanical clamps. The Oyaide outlets work this way. It will help to polish and clean the bare wires thoroughly before installing them.
