any reason why this would not work well?? pics!

As for power, you could look into those 220v twist lock connectors. That should handle a few hundred amps over 20.

maybe im a bad googler.. can you point me? cant seem to find any with much greater amp ratings.

when the connectors are rated at 20a would that mean 20a per blade or for all 3 blades combined? each of my 3 amps are fused at 60a so if this were the case, i would need one receptacle for each power run for each amplifier.
and here is a very stupid question.. 20a at 125v IS the same as 20a at 12v correct?

Yes 20A is 20A when talking about the wires capability at 12v or 125v.

I wouldnt use hospital 3 pronged connectors, the parts express connectors would be better.

I would use these personally.

this is indeed what'choo need

also the plugs are rated at 20a at 125v. any forseable problem with the 20a power ratings?

and on your cars 12 volt system that plug is gong to be good for around 200 amps which is more than you should be pulling through 4ga anyways so those will work fine and thats a very neat idea you have. i might steal it //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

ehh no......20 amps at 125v is ALOT different than at lets say 12.5v. It will be able to handle 200 amps at 12.5 volts.

Dang it, I can't seem to find those things we had in shop class 22 years ago. I would go with the Parts Express break away connector if I were you! If I find those huge plugs, I will post a link to them.

Your using ohms law top determine the VOLTAGE carrying capability of WIRE...

If what your saying is true....everyone would need 4GA speaker wire...

I know your gonna say this is AC VS DC....but.....the only difference in ohms law between the two is Resistance in DC is resistance and in AC it is Impedance.

Not trying to be an *******, but why is wire rated in current, not voltage?

you could run

10,000 volts at .01 amp through a 22 guage wire.

now im confused

also just thinking about the actual thickness of the blades on the heavy duty plugs.... they seem to be a much thicker blade/metal than my 300amp fuses that i have on my 1/0 on the boat so wouldnt this simple face mean they can handle at least that much current?

It depends on the conductive material the blade is made of, but generally when talking about the same materials mass=mass.

I would not exede recommended amperage ratings.

Im not arguing with you over this, this is simple stuff. If i am wrong and that plug truly can only handle 20 amps at 12 volts than prove it. You even said it...ohms law buddy....its designed for 120 volt and can take 20 amps. 120/12=(10)*20 amps. 200 amps. now explain to me why i am wrong. I like to learn.

lets not keep spamming this guys thread, lets keep discussing in this one.

FYI i believe the plugs you posted will work better then all of the other options people are posting

 

[funkyab 10+ year member]

i still find it difficult to believe that with the heavy guage blades and huge amount of insulation that these plugs are only rated at 20amps.

and still in the other thread regarding this topic there has yet been a consensus.

You can do whatever you want, after all its not my life your putting on the line.

If you want to be safe do not run the hospital plugs.
