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).

Can you run insulated wires in a conduit pipe?
Except for the ground wire they must be insulated.
Is it a fire hazard to double land wires on a breaker?
Yes!
Why are conductors needed?
If you want to operate the conductors maximum capacity, the conductor needs the heat, that the amperage produces, to be dissipated. This is why in the electrical code book there are two amperage ratings. The first one is for a free air rating which allows for a high ampacity of the wire. The other rating is for three conductors in a conduit which confines the cooling capacity and so the ampacity rating of these wires is lowered. The same procedure is used in cable spacings in ladder tray networks.
Do ground wires have to be covered with wire insulation?
Not always, the electrical code is quite specific as to the type of installation where the ground wire needs to be insulated and in what type of installation the ground wire can use bare copper.
What is ampacity of 25mm cable at 250 volts?
The amperage rating is dependent upon the insulation rating. A pair of 25mm squared wires touching each other are rated at 131 amps. Three 25mm squared wires touching each other are rated at 110 amps.
Why aluminium wires are not insulated?
Aluminum wires are insulated.
What will happen if wires are not insulated?
what may happen if wires are not insulated
Are wires insulated to keep then warm?
Most are insulated to keep them from grounding out or interference.
What are insulated wires made out of?
An insulated wire is made of a conductor surrounded by an insulating 'jacket'.
Can you run insulated wires in a conduit pipe?
Except for the ground wire they must be insulated.
What cases eletricity?
Insulated wires and such and batteries.
Why are most electrical wires surrounded by non-metallic materials?
Wires have to be insulated from each other to confine the current inside the wire. Most wires are insulated with a pvc sheath surrounding the copper wire.
Which does not state a principle related to why ground wires are in effective safety device?
Electronic devices are protected from power surges by having insulated wires
Insulated fittings can be used to splice wires thus eliminating the need for?
Soldering the wires together
What is the difference between insulated wire and ordinary cable?
Insulated wires and cables are commonly used conductors in power engineering
What is the primary function of the twists in the twisted pair cable?
The primary purpose of twisting wires/cables is retaining flexibility while increasing the ampacity (current capacity of wire/conductor). Twisted wire/cable is more flexible than a solid wire with same ampacity.
What are the two wires inside the cable of a hairdryer made from?
Most likely insulated copper.
