Electrical Switch Question
Hello all,
I have a question about a single pole single throw switch. On a "normal" Leviton 15 amp switch there are "secondary" attachments for power on the back via a "push in port" (for lack of a better term). So the line side has both screw terminals and this additional port (I presume to do what I want to do - bring one power line feed into a box to power 3 separately switched circuits). The problem is that the push in port only accepts 14 gauge wire and I have 12 gauge wire as this is a 20 amp circuit. Ok so I buy a 20 amp switch - no "secondary" power attachment. Why is this? Is this standard or are their 20 amp switches that mimic their 15 amp cousins so that I can run non switched power between multiple 20 amp switches in a box? TIA |

TIA The push in type connections on the back of switches or outlets are not a very reliable method of connection. They rely on a tension grip holding the wire. Over time, it's not unusual for them to come loose and be a source of things losing power or acting intermittent. If you follow the newsgroup, you will see most people recommend not using them. To do what you want, use pig tail leads within the box. For example, if you have one feed coming in and want to connect it to 2 switches, you use a wire nut to attach 2 short wires to the incoming one. Those wires then go to the switches. |

TIA What you are calling a "push in port" is often called a "back stab" connection. Compared to a screw terminal connection, a "back stab" has a relatively high failure rate. Folks who do a lot of electrical work generally tend to dislike the "back stab" connections. The old style "back stab" connections have the holes or the wire, and a small "tab" that can be pushed by a small flat blade screw driver to release the "back stab" connection. These are a really bad idea ifyou are cursed with aluminum wire. There is a newer style of back connection that seems to be a bit more reliable. These have a "port" if you will, and a screw and plate. You unloosen the screw as far as it will go, the plate sort of falls away from the port inside the body. Put the properly stripped wire (there should be a strip guide on the deice, you strip enough insulation so that the bare wire bottoms out in the hole, but no bare wire shows at the back of the device) into the "port" and srew the screw down tight which drives the plate ino clamping tight to the wire inside the "port". The "port" as you call it is really not an auxillary power feed. You use the port or the screw, not both. Standard 20 amp single pole switches tend to easily fit only one 12 ga wire around the terminal screw. With a lot of pracice and the right tools you can sometimes get a 12 and a 14 around one screw, but its bad practice. You usually don't find "ports" on 20 amp devices because ports tend to be less reliable and the NEC doesn't, AFIK, allow old style "back stab" on 20 ap devices. The new style The better method is to "pigtail" the connection, which involves wire nuts. 12 ga is a bear to work in a standard depth box. Deep boxes leave more room. Power in on 1 cable, wire nut 3 or 4 12 ga feeders to the power black, feed each switch one feeder. Connect the black wires of each separate branch to a separate switch output. All the white wires from the power feed and the branch cables get wired together. All the grounds get wired together. I'm not sure what you are trying to do, but I think you need a detailed wiring book, and maybe some professional electrician type help. This is ot complicated but 12 ga is a bear to work with. |

Ok - so these 20 amp switches are much "beefier" than a 15 amp switch. How does one put all the "pigtailed" and wirenuted stuff in a 3 1/2 inch box with the darn outlet? LOL? Not only that but once I get to the 3 switch box the amount of wire in that is huge. |

Also on a complete side note - I have noticed that the switches and outles I am using seem to have the ground screw connected right to the metal housing that attaches to the box. Is this the case and if so can I discontinue running another ground to my metal boxes as that should double as the plug ground and box ground? That will save space right there. |

Well - what I'm trying to do is relatively simple. 1 power feed 3 seperate lighting ciruits. I fully understand that I can do the work with wirenuts (though space becomes the issue). The original wiring used the "back stab" ports in this mannor so I figure I'd just mimic it. Evidently plan B and struggling to get wire in a box is the "answer" I am looking for. |

I don't think so, unless the switches you are using are "self-grounding" that is they have the little brass tab behind the mounting screw. One thing I forgot to mention was that often really old school electricians would leave the incoming black wire long, and if you have a good pair of strippers simply strip 3/4" or so of insulation at 3-5" increments until you have the same number of bare patches of wire as you do switches to which you want to connect. Then you loop the wire under the screw terminal of each switch. I don't know if this scenario meets current code or not however not being a working electrician (I know it's not acceptable for fire alarm, but for a reason that probably isn't applicable to 120V wiring.) ante -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |

If you have a metal box, which is grounded by an equipment grounding conductor, (ground wire in Romex) the screws of the wall switches are grounding them. Receptacles must have ground wires attached to them or approved self grounding receptacles must be used. |

Its not clear to me from the OP's post how many switces he is trying to drive. It might be 4, it might be 3, it might be 5. I can't tell. If its 4 or 5 switches, you just set up two clusters of pigtails. No big deal. |
