For cables in 'Free Air', that is, not routed through conduit, it depends on the Temperature rating of the cable; 60 deg C: 40 amps, 75 deg C: 50 amps, 90 deg C: 55 amps <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What is AWG in cable?
American Wire Gauge. Measure the thickness of the cable.
What do the difference sizes allow between the various sq mm wires?
The different sizes allow for different current capacities to be carried by the wire. The larger the size, the more amperage capacity is allowed. The question refers to the metric sizing of wire. North American wire sizing is still done in AWG.
What is the current carrying capacity of a 18 awg stranded wire rated to 105 deg c 600 volts with PVC insulation?
The 2005 NEC allows 14 amps for 18 AWG wire in conduit, 18 amps in free air. Solid or stranded does not matter. There is no table that allows more current with higher insulation temperature rating. These values are good only up to 86 deg F ambient temperature, and must be derated according to table 310.16 or 310.17 if the ambient temp is above 86. You must also derate for more than 3 conductors in a raceway. I have not seen a PVC insulated wire rated to 105C. Is there such a thing?
What is the maximum current carrying capacity of 35 sq mm copper wire?
The nearest AWG wire size to 50 sq. mm is 1/0. A 1/0 aluminium conductor with an insulation factor of 75 or 90 degrees C is rated at 180 and 205 amps respectively.
What size wire is utilized in low voltage systems?
If you are referring to low voltage lighting systems the current usually dictates 10 or 12 AWG, 10 is more common in my experience and the wire usually used is stranded.
What is AWG in cable?
American Wire Gauge. Measure the thickness of the cable.
Can you take a 14 awg wire and hook it to a 12 awg wire?
Yes as long as the breaker feeding the circuit is protected with a 15 amp breaker. The code states that the over current device can be no smaller than that of the smallest current carrying conductor. That will be the #14 wire with a capacity of 15 amps.
Does the AWG of a wire stand for the size of wire?
It stands for American Wire Gauge and a designation like 10 AWG indicates the size. There are a number of other specifications which derive from the cross sectional area of the wire as designated by the gauge. One confusing aspect is as the number of the gauge gets smaller the current carrying capacity increases.
How many amps service does 12 gauge yellow wire hold?
The normal current capacity of 12 AWG copper wire is 20 amps.
Which wire is smallest in AWG?
The larger the AWG number the smaller the wire. 10 AWG wire can carry more current than 12 AWG wire.The wire sizes of 24 and 26 are the smallest that are used in the electrical.See related links below
What is the difference between 1-0 wire and number 1 wire?
1-0 or 1/0 actually means one zero and is thus pronounced "won aught". In the US, wire is sized per American Wire Gauge or AWG which gets larger as the gauge size gets smaller. 1 AWG wire is pretty big wire (about 1/4" in diameter). 1/0 or "0" AWG wire is a bit larger. By contrast, 4/0 (0000) AWG wire is about 1/2" in diameter). The larger the wire, the higher the current carrying capacity.

Can you use braided wire in your breaker panel?
No. Braided wire is not considered "current-carrying". It is not sold or maufactured via AWG specs. It is manufactured via weight per foot. Braided wire is used for grounding purposes only.
What is the maximum amperes that may be applied to an electric heater circuit?
Actually, the amperage rating of the circuit is determined by the size of the wiring.The maximum current capacity of common wire sizes are:#14 AWG: 15 Amps#12 AWG: 20 Amps#10 AWG: 30 AmpsCheck the amp rating of the water heater, and make sure that the wiring that supplies it is the corresponding size. NEVERconnect wire to a breaker set for a higher current than the wire is rated for (for example, do not connect #14 wire to a 20 Amp breaker). Allowing more current in a wire is asking for a fire.The HVAC Veteran
How many amps can a 12 awg wire carry at 240 volts?
The voltage has nothing to do with the capacity of a wire to handle current. A #12 copper wire with an insulation factor of 60, 75 or 90 degrees C is rated at 20 amps.
What is the maximum apm capacity of 12 awg wire?
For typical residential application it is 20 amps.
What does AWG mean?
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.
Which is larger in diameter12 AWG or 15 AWG wire?
12 awg is larger.
