Correct. I was simply stating that to derive the performance the amp is capable of, it needs to be supplied via a 30A circuit. From dandagostino dot com: "The Relentless Monoblock can achieve its rated 1,500 watts into 8 ohms with a standard 15- or 20-amp household circuit, but achieving its rated 3,000 watts into 4 ohms and 6,000 watts into 2 ohms requires a 220-volt, 30-amp circuit of the type used for electric clothes dryers—something any electrician can install."So if the D'Agostino is on a 15A circuit and the breakers don't pop, then it's using less than 15 amps.
Breakers definitely limit current to what they are designed for. This includes some amount of overcurrent.That's not how it works, actually. The breaker does not limit the amount of current delivered to your device, nor does it impede that delivery in any way.
Correct, and most folks are unaware as to how much over the "Rated Current" the breaker will allow before a fault occurs.What it does is pop when the current being requested is greater than its rating.
Important circuit breaker characteristics include Rated Current, OverCurrent, Switching Time, and Thermal Tripper. OverCurrent, Switching Time, and Thermal Tripper all play a role in tripping the breaker under the conditions it is designed for with respect to exceeding the current rating. While it's not a "one size fits all" situation, most general household breakers for outlets allow for some amount of overcurrent for some amount of time - usually brief, like under 10 seconds (there are charts for each breaker noting the exact time based on all the variables). The more brief the occurrence, the more current is allowed to pass without fault.
For example, the breakers in my electric panel that are rated at 20A will allow 35A to pass for several seconds without fault. As a comparison, the 15A breakers will allow about 26A through for a brief amount of time. So I look at it this way, I can have a circuit that can allow 35A or one that allows only 26A for transients before thinking of getting "in the way".
So I think we're in agreement, but just wanted to clarify.
