No, code does not allow that.
6 AWG
Yes they can but the electrical code states that the wires can only be 1/0 AWG and larger.
American Wire Guage. The smaller the number the larger the wire. As in an AWG 14/2 wire is much smaller than an AWG 10/2 wire.
American Wire Gauge ( AWG )
Smaller numbers mean thicker wires
No, code does not allow that.
yes, it will in theory work, however it is a NEC violation to paralell wires smaller than 1/0, code section 310.10H.
Yes, Section 240.5(B)(2) Fixture Wires, allows #14 AWG fixture wires to be tapped to the #10 AWG branch circuit wires.
According to appendix C of the NEC, 3 #2 awg are permitted in a 1" EMT.
6 AWG
12 gauge is thicker. Household wires in the walls are mostly ga 14. Majority of wires in the car wiring are ga 16, except control wires which are thinner, like ga 18 or 20, and main battery wires wich are very thick, probably ga 4 or 6.
Twisted pair wires are rated by the American Wire Gauge (AWG) standard
Yes they can but the electrical code states that the wires can only be 1/0 AWG and larger.
I think you mean 16 AWG THWN. It's coating for PVC piping.
