Figure 1: 3Ph Supply Box
3Ph Supply Box
The 3Ph Supply Box uses safety banana jacks so you easily connect to the required equipment as needed. There are 2 equivalent (shorted together) connection points for each phase, 2 red for phase A, 2 black for phase B and 2 blue for phase C. The box also provides an Earth ground that allows you to safely ground any equipment that may need it. The output voltages available on the output safety banana jacks can be enabled or disabled by the START and STOP buttons. The indicating light is on when voltages are live on the safety banana jacks. The RESET button is unconnected and has no function. Each of the 3 phases is individually fused at 15 amps and the fuses can be accessed on the left side of the box. Please do not remove the fuses without the assistance of a Lab Instructor.
