IEC — titled Circuit Breakers for Overcurrent Protection for Household[s], [etc.] — is a widely-followed international standard which lays out preferred methods of rating and labeling low-voltage circuit breakers. IEC defines "rated current" as the maximum . Add the wattage needs for the kitchen. You need a small-appliance, amp single-pole circuit for the kitchen. Multiply 20 amps by volts for a total of 2, watts. Your total wattage now equals 7, (2, + 4, = 7,). A single-pole breaker operates at volts while a double-pole breaker operates at volts. The "size" of a circuit breaker is the maximum current that can pass through the breaker without tripping the circuit and causing a loss of power. In other words, the breaker controlling a circuit should be percent of the continuous load (maximum .
Selective Coordination - Cooper Industries. Trip elements trip the operating mechanism of a circuit breaker during either a prolonged overload or a short circuit current.
Some molded case circuit breakers have a screwdriver slot located on the front of the trip unit used for adjusting sensitivity.
The maximum setting is established by protection of the minimum conductor size in the circuit. *Same Day or Next Day Delivery available on most orders, to most areas.
