Silicone Wire Gauges Amps
 

10awg silicone wire = how much amps/constant and max amps can support ?
12awg silicone wire = how much amps/constant and max amps can support ?
13awg silicone wire = how much amps/constant and max amps can support ?

Just a guess here, but I'd say:

10awg silicone wire = 120A+
12awg silicone wire = 80A+
13awg silicone wire = 60A+

It depends A LOT on the wire's length. I based my guesses on a <6" piece of wire, and a maximum of 25V.

I've been searching for an answer to this question also.

It appears that most places that sell the wire, don't want to commit to amp carrying ability.

Indeed it does depend on the length of the run.

Here is some info from a website willing to commit to amps:

14Ga. = 35 amps
13Ga. = 50 amps
11Ga. = 100 amps

hmm I have found something on the internet :

12AWG Wire = good for 100amps +
14AWG Wire = good for 50-75amps+
16AWG Wire = good for 25-74amps.
18AWG Wire = good for 25amps.
20AWG Wire = good for 20amps.

so a 13AWG Wire should be good for 80amps+ I think..

Where did you find this? What website?

It's about voltage drop. At a given current, you don't want much more than 1% voltage drop. Wire has so much resistance per foot, the larger the wire, the lower the resistance.

From this site, 10GA wire has 0.998mOhms per foot. 16GA wire has 4.016mOhms/foot.

At 100A and 2 feet, the 10GA wire will have 0.1996 voltage drop and almost 20w being dissipated on it. At the same 100A, two feet of 16GA wire will have 0.8v dropped, and 80w being dissipated. Yikes; that would be more like a fuse than a wire...

These resistance values are probably for solid conductors, so it'll be a little off, but you get the idea...

Also voltage allow a line to let pass more amps(for more total power). That why electricity company use extreme voltage despite the inherent danger.

Actually, elec companies use high voltage because it takes less current (and wire gauge) for a given power load. Then transformers step the voltage down to something we can use.

It's mainly to cover the extreme distances between the power plant, switching stations, and transformers without too much voltage loss. I think the efficiency resulting from the lower current draw is just a side effect of the high transmission voltage... :neutral:

Voltage drop ONLY happens when there is current. Power = Volts x Current, more voltage = less current needed, therefore less voltage drop and less energy wasted.

Some equations to mess with:

Voltage drop = resistance x current
Power loss = resistance x current x current
Efficiency = (Volts - Voltage drop)/Volts
