Im looking for information regarding wiring single-family dwellinging units using "Romex"I was taught to "pigtail" ALL receptacles and switches out: 1- to make the finish side easier and 2 - if a receptacle or switch were to be removed from the circuit, by way of loose connection or the stab-in did not grab a hold and the wire came out, the remaining circuit down stream would remain energized. From my understanding this would be in Parallel.
On the flip side, the new company i work for does not pigtail anything out. We just stab all wires in the back of the devices, for speed.(its all about the money right?) So, using this method, if a problem occurred in a switch or receptacle as noted above, you would lose power downstream. Series?
Are there any Code articles that support wiring in Parallel vs. Series?
Whether you pigtail or back stab, both methods are technically parallel. I'm not going to go into which is better, there are plenty of threads debating this issue if you look around. In a series circuit, you would only have one wire in and one out and if the device is not in use the circuit is broken.
I wouldn't stab the terminals at all i mean after a while yur gonna have problems...when troubleshooting circuits in a dwelling half the time it all goes back to those stab terminals. because when u push the device back in the box it sometimes loosens up the stab and makes a loose connecton that may cause arcing..then when trying to find the problem you pull the device back out...and the stab terminal tightens making a good connection thinking you don't have a problem... so i would not suggest the stab in terminals.
Thats true and also the code does not allow a circuit to depend on the device...this meaning don't hook devices up in series..the circuit cannot rely on the device beause if the device fails the whole circuit fails
