SPACE HEATER THERMOSTAT SETTINGS
SPACE HEATER THERMOSTAT SETTINGS
(OP)
Hi gentlemen. Our purchased switchgear is about to be on site and I would like to inquire what is the appropriate setting for the space heater thermostat since this is something I and my group never set.

Is the setting of these thermostats supposed to be the responsibility of the switchgear manufacturer? Your comments is highly appreciated.

By the way, davidbeach...I was just wondering (for my knowledge)why in some places, it is not always advisable to provide thermostats in switchgear space heater circuits?

My experience with anti-condensation heaters in generators in the tropics is to run without thermostats. Often two similar heaters are wired in series to achieve the result suggested by davidbeach. That is to apply 50% voltage to achieve long life and dependability.
The optimum control of anti-condensation heaters would be with a dew-point sensor to keep the temperature above the dew point. I have never seen this type of control used. I would consider the risk of failure too great.
I would arrange the heaters for 50% voltage and leave them on all the time. For greater security, you may consider a current monitor and alarm panel on a seperate power source to warn of heater failure.

The problem is the temperature of the equipment, not the air.
The air must be kept warm enough to keep the temperature of the solid parts above the dew point.
Consider an offline generator in an unheated building with lots of open doorways and ventilation openings. On a cool evening, the iron and copper in the generator may drop to 75F or 70F. The next morning the ambient temperature may be in the mid 90's. If a breeze brings in warm moist air from a nearby wet or damp area, (ocean, lake, swamp, cooling tower, etc.)the internal parts of the machine may well be below the dew point and the result will be condensation on the iron.
A thermostat will respond to the internal air temperature, not the temperature of the iron, copper and insulators. In the morning, after a cool night, there may be enough of a temperature difference between the air and the solid parts to allow condensation to form.
Davidbeach and I would both use heaters at 50% voltage and leave them on at all times.
