wire awg

[BShady]

hello

im looking everywhere for an answer.

1) can i mix wire awg? like solder them together? (10awg and 12awg) i know that 12awg carries less amp
2) what is the diameter for 10awg wire through 16awg? every link on google gives me another answer!!
3) what is the amp rating for 10awg through 16awg? every link on google also gives me another answer!!

thank you so much.

For ebike DC use, depends on length, but 14 awg is good up to 20 amps. 12 if you run 30~40 amps and 10awg if you run more than 50 amps... when running longer than 6ft go to the next gauge wire and it's more than enough with a safe margin .

also, if you got it, or have access to it, silicone wire is the way to go .. soft , flexible and lots of fine strands ... i buy it by the 20m lot in every gauge available from hobby king.

This is the best place I've found to figure out what you need/want. Use chassis wiring amps.

Kk

But if I'm useing a Ebike or E-MTB, why would in get a 150 amp esc if the wires can't handle that amp? ( on 10awg that's what I read even 12awg)

Because a 150A ESC won't really do 150A, at least not for more than a few seconds. Wires will carry far greater than their rated current for short periods (before they overheat).

To get a straight answer, you must add much more information. Are you pushing AC or DC current. If AC, what is the frequency. Are the wires Enclosed? How tightly? How warm do you want them to get /what type of heat / friction /flex will they see in their path. All of the charts and calculators assume a certain temperature rise which may of may not fit your application. In free air the numbers can be many times higher for the same size wire. With that said, it is Perfectly acceptable to gang up strands of different gauges and wire types and at times possibly better depending on the frequencies / power ranges transmitted. The further the distance, the more it matters.

sorry about that.

all the wire im going to be using is from HK: like this http://hobbyking.com/hobbyking/store/__9678__Turnigy_Pure_Silicone_Wire_14AWG_1mtr_RED.html.

surprisingly as i was posting the link i saw in the discussions on the bottom of the page that i linked, that someone posted the amperage and size in mm! anyone could back this up?

this is it:
8AWG = 6.5MM = 200 amps,
10AWG = 5.5MM = 140 amps,
12AWG = 4.5MM = 90 amps,
14AWG = 3.5MM = 60 amps,
16AWG = 3.0MM = 35 amps,
18AWG = 2.8MM = 20 amps,
20AWG = 2.0MM = 12 amps,
22AWG = 1.7MM = 10 amps,
24AWG = 1.6MM = 6 amp

Cut those amps in half and you have realistic numbers for continuous amps. Now with a high temp sheathing, you can get more amps before it will start to melt the sheathing, but the resistance and voltage drop will be considerable more. Go with the chart in this link and you'll be fine regardless of sheathing material.

thanks

i think im going to have to do a lot of reading for these. i found on 2 old computer supplies (DELL) the 12v lead that powers the motherboard is rated at 16amp's and another at 18amp's and both have 18awg wiring at 90deg C. i would think that it is continues current?! :?

16 or 18 amps in a 18 gauge wire is temporary not continuous. It's more than double of what you can expect to carry on it full time safely. It may be better if you stated exactly what you were doing before you burn down the neighborhood.

requoting myself... come on horse.. drink. :lol:

oh sorry i didnt mean to bash anyone was just throwing it out there.

i was looking into a E-MTB just realized i posted this thread in the wrong place. sorry is there a way to transfer it?

Hi, Help!!

My new is FC-1 battery from RisunMotor.
72v 30ah battery Panasonic cell with charger.

Info will working with 2 x 10AWG Silicone Wires and ANL Fuse 100amp is fine?

Thanks.
