Single-pole circuit breakers will not be found in 3-wire, delta-supplied power panels that are not referenced to ground.
Because the grounded-neutral circuit conductor is not used in this type of electrical-power distribution, the lower phase-to-neutral voltage is not available.
The only voltage measurements available in this type of panel are between the two load terminals of a 2-pole, single-phase, phase-to-phase CB, or between any two of the three poles of a CB in a 3-phase electrical-power distribution panel.
A) True
B) False
