Create a post with the following:

  • Calculate the amperage requirements of a typical home studio setup (computer, monitors, AC powered interface, and at least one analog synthesizer) based on each unit’s power consumption (in watts) and explain how to keep from tripping a breaker with that gear.
    • watts = volts x amps

My home studio set up:

  • Computer (desktop) – 200W
  • 2 Studio monitors – 80W
  • AC Audio Interface – 20W
  • Analog Synthesizer – 50W
    • Total = 350W
    • 350W = 120V / 2.92amps
  • With this gear there should not be a risk of tripping the breaker since most US home outlets and circuits can take 15-20amps. But, some steps to make sure we do not trip a breaker is to 1) do not get close to the max wattage of a circuit, 2) know what else is on the circuit and the wattage it might contribute, 3) use surge protectors!
  • Discuss how to locate and operate the circuit breaker panel for repairs, upgrades, and when a breaker is tripped.
