Electrical feed from battery

DakarNick · 09-21-2007, 05:35 PM

I have an air compressor and power adaptor socket for phone/ipod charging hooked up. I plan to add heated grips also. More than likely they won't all be used at the same time.

I have hooked the wires directly off the battery and ran separate fuses. right now I am T-ed into the compressor wires, which I made out of 18 ga. Is that enough or should I run some 12 or 14 ga to the fuseblock I am going to get.

I know it all depends on what amps I will be pulling but I am not sure! So, what is a safe bet?

Thanks,

Nick

FWIW

18 gauge can carry about 2.3 Amps for power transmission, and is about 6.4 Ohms per 1000 feet.

(14 gauge is about 5.9 Amps for power xmission)

12 gauge can carry about 9.3 Amps for power transmission, and is about 1.6 Ohms per 1000 feet.

Ultimately it depends on the current you will draw.

Thanks! I will see what I can find for power draw and go off that!

instead of going directly off the battery, check out this setup, runs from battery, but is switched

That's a good idea. I will have one lead wire from the battery but it is on all the time. I like the switchable with accessories on idea via the relay.

I have a fuseblock though. Should I combine the negatives to a common ground since the fuseblock doesn't have one?

Thanks, Nick

I ran mine like the link, with a ground directly from the battery to the junction block. You can run a wire from the battery ground to a terminal, and then use this terminal as a common ground to run to your accessories.

As a side note, I hooked up my heated grips this afternoon, and the junction box made for a much neater and easier and quicker wiring job.
