I'm surprised manufacturers like APC wouldn't have thought of this or included this in their products?

Is there a risk to running any equipment on UPS when not plugged into mains indoors, and does it get worse if run outdoors?

is an RCD similar to an ELCB?

At astrocamps, we often use powerboards in the field and that is exposed. is that considered risky?
My concern is most of our astrogear, computers and power boards will be stamped with "Indoor Use Only". It's not uncommon for gear to be drenched in dew in our humid climate. Given my preferred dark sky site is off grid, I have little choice but to be running on 12V. Nonetheless, I don't mind running that way at home.

I've been zapped with 240V once through my own stupidity (not related to astro-gear) - doing my utmost to avoid that happening again in the future.
