But the safety mechanism lies at the breaker circuit. If your outlet is rated to 10 so must your breaker be. That way there is no risk.

What happens if one of your 10 A appliances fails and starts to draw 16 amps? Say a malfunctioning toaster.

Well for our relevant current, the smallest home socket we have is 15 A, but if something did in fact start drawing more like 16, it would probably be a slow heat until the 15 amp circuit breaker tripped, but the breaker, the wiring, and the outlet will all be rated the same if they've been installed correctly.

The point is, you can never be sure that the appliance you plug in doesnt draw more than the rating for a long variety of reasons (bad product, damaged, too many appliances connected to the same outlet etc) so if you want a safe installation you should assume this could be the case and install a breaker thats of the lowest rating in the whole system.

Well for us it means the socket and breaker should coordinate, so you can't burn the outlet before something quits.

That works when the appliances function and people havent put too many things on extension cords... i.e. there are more risks in this design...

That's an externality to what we're discussing though and is equally true of all configurations

Not really - if the breaker is dimensioned larger than the outlet material you could overload the outlet material by adding too many appliances. If the breaker is dimensioned as the outlet rating the breaker will trip if theres too much current passing through the outlet.

If the breaker is rated the same as the outlet, and the breaker trips, that is good. You don't want to start a fire in the outlet. You always want a circuit breaker to trip before excess heat is concentrated at another connection point.

But the other guys slammed on me for stating this simple fact...

I think you should go back and see what you said and see if you misphrased something, then.

Im not sure what that would be - help me out. Think I was pretty clear in my first comment

> You need to change your breakers to 10 amps also, otherwise you risk unintentionally overloading the outlets/wires or whatever is the "bottleneck".
