Motors with Space Heaters Disconnected
Motors with Space Heaters Disconnected
(OP)
I have two 30 HP motors that require heaters (due to job specifications) Because of a communication breakdown, they were brought to the job for installation which didn't take place; the temp power crew forgot to rehook the heaters up How long can they go without heat without this becoming an issue? Nite temps will be in the high teens, low 20's and it will be Monday at the earliest before connection can take place

You may be good to go on Monday or Tuesday. It may take several days or a week to dry the motors.
It depends on the ambient conditions at your job site. There is quite a thermal lag in the stator and rotor when the ambient temperature is rising. If the ambient temperature rises quickly on a morning when the relative humidity is high, the dew point may rise above the temperature of the interior of the motor. When that happens condensation forms in the motor. This may happen at any temperature and may be worse in Central America than in Many locations in Canada.
It depends. If the motors stayed dry, they may even be good to go on Monday.
If ambient conditions have been unfavorable the motors may be damp or wet internally and you may have to dry them out for several days.
Let us know how it goes. We thrive on feedback.
