What is the ampacity of the 14 conductors in the conduit application?
Emmaraleigh
14 AWG copper conductors are limited in the NEC to 15 amps. You must protect them with an overcurrent device such as a breaker or fuse not exceeding 15 amps.

What ampacity should branch circuit conductors have?
Branch circuits wire sizes are governed by the connected load amperage of the circuit. The wire size ampacity then governs the size of the breaker that is used to protect the circuit from overloading. For general home wiring circuits the conductors used are, receptacles and lighting #14 - 15 amps, dedicated circuits load dependant, hot water tank and baseboard heaters #12 - 20 amps, clothes dryer #10 - 30 amps, range #8 -- 40 amps.
What is larger 12 gauge wire or 20 gauge wire?
Yes, a #12 AWG conductor has a greater diameter than a #14 AWG conductor. A #12 conductor has an ampacity of 20 amps whereas a #14 conductor only has an ampacity of 15 amps.
What is the difference between romex 14 2 14 3?
In romex, 14-2 means two conductors, 14AWG each, and 14-3 means three conductors, 14AWG each. Note: Normally, romex has a ground, so the designation is more likely to be 14-2/G or 14-3/G.
The ampacity of NO 12 aluminum wire with RHW insulation installed in a raceway that has 19 other wires is what?
A #12 copper conductor with an insulation factor of 90 degrees C is rated at 20 amps. A #12 aluminium conductor with an insulation rating of 90 degrees C is rated at 15 amps. These conductors ratings only applies to three conductors in a raceway. To apply the derate to the conductor requires the size of the raceway. From 7 to 24 conductors in a raceway, both aluminium and copper conductor's ratings have to be reduced by .70, so 15 amps x .7 = 10.5 amps and 20 amps x .7 = 14 amps respectively.
Does the code permit the ampacity of switch legs to be less than the ampere rating of the branch circuit?
No, and here's why: the rating of the branch, determined by the overcurrent protection, is designed for the ampacity of the branch conductors so that they breaker trips before the conductors heat up enough to start a fire. If you put in smaller wires on the same branch, they will get MUCH hotter before the circuit breaker trips, if it ever does. For example, a 20A branch, protecting 12AWG wiring; add some 14 AWG rated for 15A. Something faults the switched leg at 18A; enough to burn out the wiring but not enough to trip the breaker. House burns down, insurance doesn't pay because of "faulty wiring" installed negligently by a person without proper training and credentials.
How many wires can be sent in one inch conduit?
The electrical code book provides a chart for conduit fill. The same size conductors have different types and thickness's of insulation which has to be taken into account on wire fill calculations. 1" or 27 mm conduit can carry the following amount of RW90 insulated conductors.25 - #14, 19 - #12, 14 - #10, 7 - #8, 10 - #6, 4 - #4, 3 - #3, 3 - #2,and 1 - #1.

What is larger 12 gauge wire or 20 gauge wire?
Yes, a #12 AWG conductor has a greater diameter than a #14 AWG conductor. A #12 conductor has an ampacity of 20 amps whereas a #14 conductor only has an ampacity of 15 amps.

What are the ratings and certificates for The Unit - 2006 The Conduit 4-4?
The Unit - 2006 The Conduit 4-4 is rated/received certificates of: USA:TV-14 (LV)
Can 12-2 wire be used where only 14-2 wire is required?
Yes the ampacity of #12 is 20 amps whereas the ampacity of #14 is 15 amps, so you are well within the range using #12 wire.
Continuous loads are calculated at what percenteage of the connected load?
"... the rating of the overcurrent device shall not be less than the non-continuous load plus 125% of the continuous load." NEC 2008 Article 210.20(A) Furthermore, the ampacity of the conductor must be derated to 80% of allowable ampacity as stated in Table 310.16. Please take note of the exception to the table for #14 AWG, #12 AWG, and #10 AWG in Article 240.4(D) which automatically derates small conductors such as these to 15A, 20A, and 30A respectively. Also be aware of all other ampacity derating that may be required by Article 310 and Article 422.
What is the difference between romex 14 2 14 3?
In romex, 14-2 means two conductors, 14AWG each, and 14-3 means three conductors, 14AWG each. Note: Normally, romex has a ground, so the designation is more likely to be 14-2/G or 14-3/G.
The ampacity of a No. 12 aluminum wire with RHW insulation installed in a raceway that has 19 other wires is?
A #12 copper conductor with an insulation factor of 90 degrees C is rated at 20 amps. A #12 aluminium conductor with an insulation rating of 90 degrees C is rated at 15 amps. These conductors ratings only applies to three conductors in a raceway. To apply the derate to the conductor requires the size of the raceway. From 7 to 24 conductors in a raceway, both aluminium and copper conductor's ratings have to be reduced by .70, so 15 amps x .7 = 10.5 amps and 20 amps x .7 = 14 amps respectively.
Can you use single conductor 14 gauge wire to wire a three way switch?
The key is the protection of the wires. If you are using single wires you will need a conduit of some sort. Don't just run the single wires in the wall. Multi wire Romex or metallic shielded cable are used to provided added protection to the encased conductors.
