It's hard to train someone not to do something that they already know they shouldn't do. Everyone knows they shouldn't touch bare wires, but unless you work with electrical circuits regularly, it's hard to develop the practices that keep you from accidentally brushing against an exposed wire. And cutting over to the emergency generator is something that happens rarely. It's unconscionable that they didn't have NEC compliant covers over all exposed wiring. And they shouldn't even be flipping breakers (unless interlocked) to transfer power, they should just be flipping a transfer switch. If they really need to get to the wiring to fix something, it only takes a minute with a screwdriver to take off the cover.

>Everyone knows they shouldn't touch bare wires, but unless you work with electrical circuits regularly, it's hard to develop the practices that keep you from accidentally brushing against an exposed wire. Eh, I'd say even with experience it's hard to drill in, because someone with experience has probably brushed up against something running supposedly lethal voltage once in their life, and walked away with only a startle and a tingly arm, breeding complacency

Set up right they should not have even needed to flip a transfer switch. The generator would be feeding a large ac to dc battery charger, which charges the same battery bank which is connected to the pv charge controller. You can parallel the outputs of an ac-to-dc battery charger and a pv charge controller together onto the same battery bus, with appropriate DC breakers in place. Simply start the generator and the battery bank begins receeiving charge. There are pv charge controllers (Schneider electric) which support generator auto start based on a low voltage threshold.

I mean this is harsh but how dump are the people you work with if this is how you see people? Not touching a wire is easy to do. If you can't do that perhaps you shouldn't be participating.

  Not touching a wire is easy to do. If you can't do that perhaps you shouldn't be participating. Accidentally touching a live wire is very easy to do, all it takes is a moment of inattention when you put your hand down or a reflexive action to catch a dropped flashlight. That's why electrical code doesn't allow any exposed wires, even in breaker boxes in a locked utility room.

    Even better you can't have exposed insulated wires. Wires have to be insulated and then they need to be covered. Either run through conduit or with a second insulating jacket ala Romex.
