I install a replacement electric cooktop in the kitchen. It's rated for a 30A breaker for all 7 burners running on high ALL AT ONCE. I only have a 20A circuit. I ask the installer what to do explaining our use case. We only use one to a maximum of three of the seven burners at a time and usually with a 5 setting not 9. He says if that's the case it will work fine but if you start using 5 burners at once the circuit breaker could trip. It's been in the house 7 years now and the circuit never tripped.
It's much the same with sound systems. People look at the max wattage quoted for amps and add them all up thinking that's what they need for power. In reality, users will never use even 40% of the total and never trip a breaker. If a breaker does trip it's likely a short in the equipment rather than amps needing more power than a 15A circuit can provide. In that case, I actually want a more sensitive breaker. The pain from extremely loud environment usually kicks in before a breaker trip.
