hey guys wasn't sure where to post this.

i got som thick speaker wire with my wiring kit and have no use for it. anyway i am putting a neon in the boot and my way of hooking it up is by running this speaker wire with a ten amp fuse just the same way as we hook up an amp. then what i want to do is run the neon ground cable to the boot grounding switch which i think of it as sort a remote or trigger wire thing.

anyway do you reckon the spaker wire would be able tohave 10amp in it.



Cheers

How thick is it? Would the diameter of the copper (not including insulation) be 1mm or more? If so then it would be fine for 12v applications, after all copper is copper.....
There will be some who no doubt will dissagree with me as I have been told by sales people the welding cable (which I use to supply my amps) is resistive.....
Go figure...

it would be fine to power neons as Interceptor said, but I'd run a smaller fuse. Then you have all bases covered, if there is a fault the fuse will blow before the wiring gets hot.

generally only go slightly higher than the current draw of whatever the wire is powering

the neon doesn't say anything about what it draws so i think i am going to just put a 10 amp fuse an see how i go. oh hang on, what about i just put the same size fuse that is on the neon cable. the neons fuse is 1A250V. from what i understand it should be 1 amp 250vols. so i think i will just put a 5 amp fuse.

Thats way too high considering the neon fuse is 1A. Maybe 5% tolerance on top is the way to go.

See what fuses you can get hold of if you can get less than 5A then go for it otherwise 5A should be ok...

The one amp fuse is to protect the neon. The fuse you are installing is to protect the wiring. 5 amp would do but if it were me I'd go with a 2 amp. You will be able to get them at an elecrtonics store like d**k Smith's.

not really, but they've been going for almost a year perfectly now.
look how thin the factory wire is that powers the headlight globes and the factory horn!

It's a good point however. Many people think they need to use thick wire and they dig deep in their pockets when they don't actually need to.. If it doesn't break don't fix it.

sometimes a bit of preventative overkill saves a lot of expense and heartbreak later
when i installed a new pair of driving lights on my XF i stripped out the factory wiring loom and replaced all the foglight wiring, relay, etc with new stuff cos i simply didnt know it's true condition or capacity

i've got a pair of Hella 181's with IPF 130w bulbs in them, which means at the 13.4V i get at highway speed they draw a total of 19.4A, which is more than what a single run of 4mm is rated at, so there's 6mm between the battery and the relay with a fuse in the middle, and a pair of 4mm wires going to the foglight mounts

if you're running a pair of small 55w fog/driving lights, fair enough, but what if you want to upgrade later?

it's better to spend a lil extra initially and have a setup that you know is capable of handling it's job and even any possible upgrades than to either have to replace all your work down the track when you want to upgrade, or god forbid sitting at the side of the road in the rain one night when something has burnt out

IIRC a 30m roll of 4mm wire only cost me $20.....
