Title: Will sticking wire along in with a fuse increase load on fuse?
Post by: madsb on 04 June 2013, 17:26
Well basically the question the title says.. If I put wire on one end of the fuse and put the fuse back in the box, will drawing power from that wire increase the load on the fuse? I think no, but I'm really not sure..

I'd like to hear you explain that to the nice man from the fire brigade.... :grin:

Why lol? Sorry but uprating fuses is never a good idea, let alone adding bits of wire in!

Haha no fire lol.. Same principle as a fuse tap, just the hack solution...

Just to satisfy my curiosity, what is the purpose of doing this?

Think about it, if you pull more amps through a fuse than the fuse is rated for it blows.....

if you stick a wire parallel to a fuse the current will split.... how much goes where depends on the resistance of each path. this cannot be accurately predicted even when only using 2 wires of the same diameter (length of wire will already make a difference, then how it's connected up)....

very daft to try this with fuse (even if fuse blows the wire will still be there and happily conduct many amps => buy some cookies for the fire department before attempting)

Honestly don't get why you all think this will blow up.. The stereo has been powered by this since I got it ( ddidn't do it)

just get the right fuse for the radio. if it's a goid radio it will have a fuse as well and maybe the amp too.  as above not a good idea as it is a hazard.. insurance null and void if they find it...:)

Wait gonna have to explain what you mean better think everyone's getting thw wrong end of the stick.

I understand what he's done just not why.. it takes minutes to run a wire with an inline fuse straight from the battery if you just need juice for something like a stereo.

This is basically the principle ... I AM going to run a wire from the battery, dont worry, jeez..  :grin:

I was just curious whether drawing power from this would increase the load (amperage) on the fuse it self... Which someone has yet to answer me..

Depends which side of the fuse you're putting that on. If it's on the battery voltage side then no. Other side I.e current goes through fuse first then yes.

Absolutely fine to do it within reason. What are you trying to wire and where?

I've done it before for some LED dash lights when they packed up on our old car. I tapped into the wire after the fuse for the sidelights and LEDs draw no current at all really.

Not too keen on the look of those things, positive unshielded voltage...

Thank you for the answer, makes sense. Basically just wiring in a central locking kit i got (vacuum system was completely busted) i need to go to a car electronics store today to get the means for wiring from battery :)

Without getting technical yes

That all depends on which side of the fuse. ;)

why would you use that thing anyway? just use the original remote locking wiring harness.... that has own lines for 12V and so on and comes from the back of the cental electric - more or less ready to use.

I am using the original wiring harness :) at least going through the door sockets. The 12 v is that the white/red wires?

Your bypassing the fuse, ie taking the safety out. Not good if you are loading cables with more than the they can handle.

yeah white/red one is the permanent +12v

No you're not at all.

Say you took it from the non fused side and put your own, smaller inline fuse, you'd not be putting any more load on the fuse at all but you would the wiring which could be more dangerous.

Taking it from the other side you would be putting more load on it.

There is only one side you SHOULD be taking it from though as the fuse will be rated slightly lower than the wiring if all is factory.
