Sizing Space heaters.
Sizing Space heaters.
(OP)
I have generators that have very low mega readings when idle. The problem has been narrowed down to the cable and insulation box on the generator. I want to add space heaters in the box that is about 3'L x 2'W 6'H, and opens at the top into the generator. I am thinking 3 500W space heaters, spaced evenly inside the box connected across 208V. Is this sufficient to heat up the box?

I could be wrong, I think "dedi" meant to say 3each 500 watt heaters. Still too much heat (me thinks).

3x500 W or 3500 W, you'll still fry the cables.

As previous posts have eluded, you do not need allot of heat. Just 100-200w could be enough.
I have used Hoffman brand enclosure heater. These are self regulating and designed to do just what you need to do. May I suggest you seek them or Rittal or other electrical encloser mfg. for advice. This is real simple.

Beware that space heater could be used not only to prevent freezing in winter time but also to prevent condensation and moisture accumulation in other seasons.
The enclose table could help you to determine the minimum size of heater.
