I've mentioned it in the past, and got the impression it went over like a fart in church, but it seems to me buttoning up a battery box tighter than a bull's ass in fly season, and (hoping) mechanical ventilation mitigates this creation of a hazardous environment creates a Class I, Division 2
Hi Dan
OK I'll bite.
1. By mechanical do you mean passive or active air movement?
2. If by hazardous you mean a hydrogen explosion, correct?
Thanks

Wrenches, wrenchers and wrenchees,
I've got a pump control question. Working on a stand-alone pumping station
in Haiti. I am planning on using a Grundfos SQflex pumping system with a
Cu 200 and a float switch. Also needed on site, is a small pressure pump
to force water through a purification
Mac:
We've dealt with this. The best solution is altitude. If there is any
terrain on which you could put the tank, you save a lot of complexity.
Alternatively, can the well pump deliver into a pressure tank,
pre-pressurizing the water? This would also save a bunch of extra parts.
Mac,
No, I haven't done it, so take this with a grain of salt...
Here's a simple mechanical approach: have you considered a
dual-action float switch on the PV input to the CU200? Check out SJE

Dan,
While the battery box, or maybe the whole room they are in, do fit the
definition of a Class 1 Division 2 location, I don't think it is
consistent with the intent of that section. Wring methods for hazardous
locations are specifically designed to keep the wiring isolated from the
