    Ground strap required for fan?

    Hi, When would you need a grounding strap for a fan. The fan in question is a 3.50A, 28VDC Fan from Ametek. The fan is not bonded to the structure where it is installed and the only ground is from 28VDC return. Thanks,

    400Hz inverter feeding 60Hz transformer?

    Actually, I was inquiring if a 115V AC 400HZ inverter source were supplying power to a 115V/5V AC 60 HZ transformer. Would saturation occur as well in this configuration? Thanks,

    3 Phase Heater

    Redtrumpet, I know the formula, I wanted to know how wirenut assumed that it was a delta? It could have been a star? I don't work with motors and nameplates on an everyday basis so that is why I am asking?

    3 Phase Heater

    Wirenut, Can you please further explain your calculation. Is the 480V a line-line or phase voltage from a delta or a star. If I assume the 480V is line-line and that the 72kW heater is a delta, I get 29A. However, if I assume it is a star, my calculation is 29A. Which is it? For a delta...
