Breakers
Different regions of the world have different sizing requirements for branch circuit conductors and
circuit breakers. In Europe and other regions where IEC standards apply, circuits breakers generally
are rated at 100% utilization, meaning that a device connected to a dedicated branch circuit may draw
a maximum current up to the circuit breaker rating. In the United States, the NEC generally specifies
what is known as the "80% rule" which requires branch circuits to be rated at 1.25 times the maximum
nameplate rating of the connected device.
Standard circuit breaker sizes also vary by region. The table below provides guidance for circuit
breaker sizing for various nominal mains voltages. The guidance for North American mains voltages
(120, 208, and 240 V) includes the 1.25 factor associated with the 80% rule. Guidance for the other
voltages (100, 200, and 230 V) assumes 100% utilization. By comparing the table above with the table
below, it may be seen that for the AC6801B and AC6802B models, the smallest standard size breaker
affords more than enough capability to supply the device. The AC6803B and AC6804B products drawn
higher currents and therefore are more likely to require higher breaker current ratings and dedicated
circuits.
For convenience, notes below the table give standard breaker sizes per IEC/EN 60898-1 and the NEC
for the United States.
Consult with local authorities to ensure full compliance with electrical code and safety requirements
before connecting any AC6800B Series instrument.
