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 else can I help you with?
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.
What is the maximum current capacity in AWG for a 50-amp circuit?
The maximum current capacity in American Wire Gauge (AWG) for a 50-amp circuit is typically AWG 6.
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.
What is the recommended wire gauge for carrying 80 amps of current?
The recommended wire gauge for carrying 80 amps of current is typically 6 AWG (American Wire Gauge).
What is the recommended wire size for a circuit carrying 35 amps of current?
The recommended wire size for a circuit carrying 35 amps of current is typically 8 AWG (American Wire Gauge).
What is the recommended wire size for a circuit carrying 80 amps of current?
The recommended wire size for a circuit carrying 80 amps of current is typically 4 AWG (American Wire Gauge).
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.
Can a 8 awg wire be replaced by 2 10 awg wires?
No, a single 8 AWG wire cannot be replaced by two 10 AWG wires in terms of electrical capacity and current-carrying capability. The 8 AWG wire has a larger cross-sectional area and can handle more current compared to two 10 AWG wires combined. It's important to match the wire gauge with the specific requirements of the circuit to ensure safety and proper functioning.
How do you calculate gauge of wire depending on current?
To calculate the gauge of wire based on current carrying capacity, you can use the American Wire Gauge (AWG) standard. The AWG table provides a reference for selecting the appropriate gauge wire for a given current rating. Choose a wire gauge that can safely carry the expected current without overheating. It's important to consider factors like wire length, insulation, and ambient temperature when determining the appropriate wire gauge for a specific application.
What fuse for AWG?
The appropriate fuse for an AWG (American Wire Gauge) size depends on the wire's current-carrying capacity, which varies based on the wire's gauge, insulation type, and installation conditions. For example, a 14 AWG wire typically has a maximum safe current rating of about 15 amps, so a 15-amp fuse would be suitable. It's essential to consult the National Electrical Code (NEC) or manufacturer's guidelines for specific applications to ensure safety and compliance. Always prioritize using a fuse that matches the wire's capacity to prevent overheating and potential fire hazards.
What is the current rating of an 18 AWG wire?
The current rating of an 18 AWG wire is typically around 16 amps.
How many amps service does 12 gauge yellow wire hold?
The normal current capacity of 12 AWG copper wire is 20 amps.
