Wire Gauges

I'm about to wire up a Podigy Brake Controller. If the truth be known I'm gettinging the bits so that my electrician son can do it for me.

Now the Yankee instructions specify minimum 14 gauge wire.

Is 14g an international standard or do I need to convert that size to "Australian Speak" when I front into Jaycar to purchase the required run from the controller back to the camper trailer?

Any assistance would be appreciated. Just in case no one has picked it up, I'm a complete novice at this electrical stuff.

As`long as it'si 14AWG (American Wire Gauge) or 14B&S (Brown & Sharpe), they're the same thing. B&S became AWG.

There is the British SWG, which is totally different.

In aussie speak -

If it's a single axle (2 x magnets) 4mm for the blue is adequate but 6mm is the norm, especially for tandems.

The red only needs to be 3 or 4 mm.

Let the auto electrician supply the wire and fuse.

Regards

Thanks Mike & Dunaruma,

You have given me something to start with.

As I said in my post, I wish to have the right bits and pieces for my electrician son to kick off with. If I was giving it to an auto electrician I would let him do the whole job but after a number of half arsed jobs charged at extortionate rates and sub standard results I'm more than happy to approach this job from a diferent direction. Son is more than happy to do it, I just wish to do the running around to save his time.

. . . exactly. A friend got a quote for 4 gauge wiring to the Rear of the Troopy by his "friendly" Auto Electrician.

When he went to pick it up he had wired it with totally useless 4mm wire.

Hi Ian 14awg is 4mm wiring in my trade i use 5mm twin it solves vd( volt drop) and most trailer plugs will accept the connection of the 5mm wire saves a lot of hassles later on and gives peace of mind knowing you have compensated for all adverse contingensies
