Answer / dushyant patel
Depend upon the thermal characteristic of the winding and
type of insulation and cooling system provided maximum start
from the cold is allowed 3 withing an hour.
Due to 7 to 10 times of starting current winding requires to
be cooled. Thermal capacity used is provided by the smart
motor protection relays and that relay is not allowed to
start the motor until and unless thermal capacity after
cooling down is reset.

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
