Answer / Sujata Gupta

A Constant Voltage Transformer (CVT) is designed to maintain a constant output voltage regardless of the load. Starting it with no load causes the initial current to be zero, which reduces stress on the windings and ensures a smooth start. If a CVT is started with a load, it may overheat due to the sudden increase in current, which can cause damage to the transformer.

Before i went to bed my master bathroom lights were working fine. At 2 am, when I went to use the lights, none of them were working. The outlets throughout the bathroom work, but the lights and fan above the toilet don't. I have two panels of switches. The one panel has four switches. One of the switches turns on the hall light, and that works. The other three are to other lights, and they don't. The other panel has three switches. One of those is to the fan, and the other is to a light above the toilet. The other is a to light that is also on that other panel. I tried the breakers, and the one that turns off the outlets, marked for the bathrooom, turns on and off the outlets. None seemed to be tripped. I checked the lightbulbs, and they are fine. Please help
