why would a 30 hurt more than a 15 both are 120 volt???? the size of the breaker has nothing to do with the "shock condition" the breaker does not have anything to do with how much amperage or voltage a circut puts out only that it will trip off when the load on the circut reaches the breakers rating
Getting shocked by either is stupid, and I would not suggest it to anyone. I also did not say anything about the breaker. A 30 amp circuit should have a larger wire size. The larger wire has the potential to move much more current then the smaller wire. This results in a larger draw in the case of a short. It is the same as saying, would you rather get shot by 1/2" water stream at 100 psi or a 5" water line at 100 psi. The 1/2" is going to hurt like all heck, the 5" of going to blow you accross the room.
I didn't say breaker (once again) and power it the volts times the amps. So saying power has nothing to do with amps is wrong. You need to stop assuming I am talking about the breaker all the time. I didn't want to write a essay on this, but here we go.how do you think a house can be either 100 or 200 amp service without needing all new appliances? the reason for max circut sizes is that you can overheat a wire or circut in an appliance without blowing the breaker causing damage or a fire, it has nothing to do with how much power the circut puts out since its always 120v (on a single breaker) 60hz.
Here is one of many reasons why we should not plug in something meant for a 15/20 amp circuit, into a 30 amp circuit. A 30 amp circuit will have a larger wire size than a 15/20 amp service. It is protected by a breaker that is meant to trip if the load exceeds the limit of the circuit/wire (30 amps). Now you plug in something that is designed to be on a 15/20 amp circuit. This piece of equipment will most likely have smaller wire designed for a 20 amp circuit. This piece of equipment fails and begins to draw more current than it was designed for (say 29 amps), but not enough to trip the 30 amp breaker. The breaker, meant to protect your home in this instance, fails to trip because it does not know there is a problem (it only senses 29 amps). The equipment, designed to draw a max of 20 amps is now drawing 29 amps. The wire inside the equipment gets hot enough to start a fire. Does that sound safe to you??? You can install a 20 amp fuse on all your equipment, but I don't see the poster doing that.
Transformers step down voltage. Voltage does not equal power. You can draw the same amount of power at 12v/120v/12000v.If less [power] is needed it would have to be stepped down by a transformer not a smaller breaker thus the wall wart style plug.
Who has a better understanding of electricity? Who is giving bad advise?
