At what point is disconnecting battery negative really not that important?

So is there any difference between disconnecting inline fuse by battery from disconnecting battery neg? Because some people say do both... fuse is a whole lot easier to take out and put back in!
i always pull al my fuses when moving stuff or installing ..never unhooked my battery unless of course im removing.the battery(s) for some reason

 
May I suggest using a ground bar with a single 1/0 from battery to the bar? Then all you need to do is un hook at that point and isolate the end from contacting medal Islide my loom over the end then tape up when I need to do this. I had a similar issue but mine was more that the Mini batteries are located near fire wall and did not like being that close to the hood.
What is a ground bar? Thanks for the suggestion

Disconnecting the ground protects entire electrical system from short circuit eg. airbag discharg accidentally or frying some sensor in more modern vehicle. Removing fus only prevents that circuit from energizing but still potential to short other circuits if screw ran threw or many other f-ups that can happen without thinking.

Thanks for the reply. The way I see it, if i'm moving around amps a far better (and easier) way to prevent circuit issues is to pull that inline fuse and maybe for extra measure pull the amp fuses until inline is reinstalled. Does this seem like a good idea?

A ground bar is usualy a piece of copper you can get from electrical supply house that would allo you to run all your grounds to withou connecting to battery. It is similar to a distro block but no fuses.

 
what exactly are u wanting to do that u think u gota unhook the battery neg?
Uninstall amp, reinstall new amp in its place, take out and put in power and ground wires into dist blocks... basically just that stuff

If screw ran through? What do you mean by that? I do see what you are saying though

 
yea i just changed out 2 batteries added aluminum buss bars to them and moved amp and few other things and i never unhooked my battery ..im sure theres plenty of stories off people still finding ways to fvck **** up ...i guess if.u wana be extra careful u can unhook it

Yeah for this install I might just undo it, but good to know for future reference when I don't really need to do it. Thanks for the advice!

If using a screw to bolt something down or just screw driver slipping and hitting existing wires. Im an electrician by trade I have seen a million different accidents that have occured from accidental stupidity I call it. Drilling through something without checking the other side is a common one. I drive a car that the electrical system is sensitive and shop labor is expensive so I take precautions as much as I can. Ever see a tech take an airbag to the head while working on a dash I have not only does it **** for the poor bastard that got hit but its an expensive screw up. And for all that ay they never have screwed up you either dont do anything or just havent been doing it long enough.

Yup I hear you.. can you repeat what you meant on that last sentence? I didn't really understand that

I have been in electrical field 13 years car audio on/off for 16. The guys that usually say I never screw up or I've never done that generally are the guys that dont do a **** thing or are new and havent experienced a good screw up yet. Its kind of like saying theres 2 types of Motorcyclist those that have laid 1 down and those that havnt laid it down.... YET. In electrical work no matter what you will have times where stuff happens that you dont think you are gnna do.

 
Okay okay... well if I'm doing anything remotely significant I'll be sure to remember it! //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

 
Hey bro, cool story! Lol really though. So you actually got shocked?
Hell yeah it came through the key i still had in my hand
