What is an appropriate temperature difference between the inside and
outside of a heated marine electrical enclosure to prevent condensation?
The application is an enclosed motor starter panel on a harbor tug. The
heater runs whenever the motor is stopped to keep the panel a certain number
of degrees above ambient temperature so that moisture will not condense on
the equipment.
Thank-you for any suggestions.

The way I understand it is a minimal heater wattage in the area of 100
Watts +/- depending upon the actual enclosure size may be sufficient.

The idea is any temperature above ambient will prevent condensation.
On some large drive enclosures the manufacturer installed 250 watt
thermostatically controlled heaters for a cooling tower we converted to
VFD's. The enclosure was about 4'H x 3' W x 2' D
I recommend you contact a strip heater manufaturer, I'm sure there is a
very specific rule of thumb to follow.
