Similarly, wife and I wear silicon wedding rings. Me because doing lot of electrical work, she because she's a climber. Similarly, when I followed the Braves as a kid, a pitcher who'd played basketball in college was walking down the street with his teammates, and was bragging about being able to dunk; so he jumped up to do a mock dunk on an awning, it caught his ring, and tore ligaments in his hand - never fully recovered his career. Not quite as gruesome as above, but it stuck with me.
Anyhow, glad I appear to be erring on the side of too careful, instead of not careful enough, with these PV cables.

An old electricians trick is keep one hand in your pocket. If your shoes are insulated and you are not leaning against something, generally you are alright, unlike this fellow:

Their green handle wire cutters seem to be OK though.Leave a comment:

So how would a solar panel complete it's circuit if one of the MC4 connectors isn't connected to anything? Remember, the current has to go back to the source, so how would current go back to the source (solar panel) if one of the MC4 connectors isn't connected to anything?Leave a comment:

I don't think we're really disagreeing here. Yes, you need to complete a circuit to get shocked. And standing on the ground will do it (whether it be ungrounded conductor in your house or PV wire). And yes, if you're insulated well enough from the ground, you won't get shocked.Leave a comment:

The ground is a likely a different potential (lower or higher would do it). Ever accidentally touch the ungrounded conductor in your house wiring ? You didn't need to also be touching neutral or ground to get shocked.
The point is, since they can fly they do not have to have their feet on the ground.
Again without completing a circuit the higher potential voltage has no where to go.
I do understand about the birds though. But have you seen a kite string bridge two power line conductors? That is a very visual site to see.Leave a comment:

Oh and birds do not get shocked while sitting on a single wire because they are not creating a circuit. It is not because they can fly.

This is why helicopters can work on 100 kilovolt transmission lines while they are operating.. it is also why birds can land on a wire and not get fried.
