#1: I believe most of this is 14AWG. There might be some 12AWG, bottom left.

[Linked Image]

#2: Is it permissible to loop conductors around the screws as is shown here? The top has third conductor, barely under the screw.

[Linked Image]

#3: A little movement and the conductor came loose.

3 wires under one terminal..that's a no no.

i have seen this practice many times were a single conductor is wrap around 1 terminal

the white wires on the switch is not marked with black tape. this is a hot conductor.

i hope this box had an exstention ring.that adds to the total cubic inch of the box

and where are the grounds from the 2 romex cable.

I don't see an extender ring....

Was this four (two duplex) switches in one 4 x 4?

Now think about this; how else could you make up that box, if the boss only gave you ONE WIRENUT??

That's all I see.
BTW; it looks like the ground conductors from the NMC are "there", but there is no ground screw/clip visable.

A lot of effort went into putting that mess together.

That looks like its been there awhile. If I did that there would be a fire in about 2 days! Or less.

OK, OK, here's the story.

[Linked Image] THIS WAS IN THE DETATCHED GARAGE AT MY HOUSE WHEN I MOVED IN! [Linked Image]

(Sorry for shouting.)

Can you believe it? No, there was not an extender on the box. There was a duplex switch (am I using the correct term) on the right--a switch over a switch. To the left was a 3-way. This whole mess follows underground back to the house where the second 3-way switch is located.

There also had been a duplex receptacle further down the line, which had a strange characteristic: Plugging in a device in the top receptacle disabled the bottom one.

When I opened up the device, I found some spider eggs in there. I wonder if that had something to do with it.

Yes, it does appear that somebody spent quite some time putting it all together.

Here's how it was grounded:

It appears to me that the bare wire is of a smaller gauge than the others.

lighthouse: As to the practice of looping the conductor around (that is, removing some insulation without cutting the conductor) -- was that ever OK as per the NEC?

I don't know of any code rule that says you can't loop a wire around the screw terminal of a device and continue to another device. This practice was, at one time, required by the specs for a major fast food chain for the outlets that served the cash registers.

ThinkGood...i did not find anything in the code book saying you can or can not do this.the only thing i found on this is article 110-14-a ...i do see this done all the time in old res wiring(knob and tube)the wire comes into the box around the screw and off to the next sw/rec with about 2/3 inches of wire in the box.it's allway fun trying to change the sw or rec.

ThinkGood,

The reduced ground wire dates that piece of romex (is it UF?) to the mid '60s.
