What is the smallest size wire that can be installed in a parallel permitted by the nec?
1/0 wire
What is the minimum wire size for desk lamp cords?
Most lamp wire is parallel #16 conductors.
What is the smallest copper wire size permitted by the national electric code for a 20 amp single phase electrical circuit?
I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.
What is the wire size needed to feed a 400 amp service with parallel copper?
It depends on the length of the run
What size wire would you use for a 70KW 240 vac single phase generator?
To calculate the wire size you would have to find the amperage. I = W/E, 70000/240 = 291.67 amps. The wire size according to code has to be up sized to 125%. 291.67 x 125% = 364.6. 500MCM copper wire with an insulation factor of 75 and 90 degrees C is rated at 380 and 395 amps respectively. If parallel conductors were used the wire size for 75 degree wire would be 3/0 rated at 200 amps. Parallel conductors for 90 degree wire would be 2/0 rated at 185 amps.
What is the smallest size wire that can be installed in a parallel permitted by the nec?
1/0 wire
What is the smallest size wire that can be installed in a parallel permitted be the nec?
1/0 wire
Is 350mcm size wire the smallest wire that can be installed in a parallel permitted by the nec?
In the CEC only 1/0 and larger conductors can be run in parallel.
What is the minimum wire size for desk lamp cords?
Most lamp wire is parallel #16 conductors.
What is the smallest wire size for which overcurrent protection is specified in the Code?
14 AWG
Can you double up on insulated wires for greater ampacity?
According to the 2008 National Electrical Code, the smallest wire that can be run in parallel is a 1/0 AWG (American Wire Gauge). If the wire you are using is smaller than a 1/0 AWG, you will need to increase the size of the wire to handle the amperage (Table 310.16 of the NEC).
What is the minimum size wire allowed for a parallel run?
The minimum size wire that can be paralleled together stated in the electrical code book is a #3 copper conductor.
What is the smallest copper wire size permitted by the national electric code for a 20 amp single phase electrical circuit?

What is the minimum size AWG copper conductor permitted for conductors with a 0 to 2000v voltage rating?
When you talk of voltage, you should be thinking of the insulation factor of the wire. By the same token when you talk of wire size, it is based on the amperage the wire is required to handle.
What is the wire size needed to feed a 400 amp service with parallel copper?
It depends on the length of the run
Can i wire two different size wires together?
To do so LEGALLY, the circuit breaker must not be rated at a capacity (in AMPS) greater than the SMALLEST wire.
When installing a new 15A GFCI circuit for a whirpool bath what size ground in addition to 12-2 wire is required?
It should be on a 20 amp breaker with #12 THHN wire. The grounding wire is typically permitted to be one size smaller, so #14 AWG bare or green wire for ground.
