Earth lead for Amp

[hon_n_gem]

Does the earth lead for an amp have to be High Tension? And also, does it depend upon length? My desired location of my Amp, means that my supplied lead is not long enough. Ive noticed that the one i currently got is HT, do all earth leads have to be HT? Also do they have to be relatively short? Say 40cm max? Or can they be as long as i want? Thanks

It has to be at least the same size as your power cable and I wouldnt have it longer than a metre

 

[cliokid]

With OutKa5t on this one.

Keep it short and the same gauge as your power cable.

 

[Gazza]

The earth should be as short as possible.

find an earthing point as close to the amp as possible
alternatively make one yaself

Well i brought a new cable, its about half the size and about 1metre long. Is that ok or is it at risk? Please tell me cause i dont wana blow all my equipment up, cheerz!

are you saying the ground cable is half the gauge of the power cable?

If so I would change it for one that is as thick as your power cable.

Its for safety as much as protecting your equipment. Think what a fuse does - its lower current to blow safely if ever there is a short. If the earth cable is not capable of carrying a high current, it will become one very long fuse wire.

OK extreme example but it could happen.

ok, ill get a new earth lead, but is the length (1M) ok? Is it too long? Im re-doin my whole ICE on Monday for the meet on 3rd so ill need a new cable again. Thanks for the help

a good place to earth your amp or amps is 1 or 2 of the seat belt fixings points under your back seats and they are well close to the amps 2 birds with 1 stone
