In most cases, the control transformer is used to reduce the main or line voltage of 240 VAC or 480 VAC to a control voltage of 120 VAC. Notice that the primary windings are crossed. This is done so that metal links can be used to connect the primaries for either 240 or 480 VAC operation, as shown in Figure 1.10.

Output regulation of +/- 0.25% of DC voltage setting with input line variations of +10%/12% voltage and/or +/-5% frequency with load variations from no load to full load over the operating DC voltage range. For extended operating DC voltage ranges regulation may not meet regulation of +/-0.25%.

Feb 28, 2013 · The MCCBs used in high-resistance-grounded systems should be rated for line-to-line voltage (480 V not 480/277 V for a 480 nominal system voltage). (Also the single-pole interrupting rating should be checked to clear the second fault on a different phase: ground as well as line-to-ground faults on two separate phases, one on each side of the ...
