What is worse; the buzz you get from 2,400 volts, 1,200 volts, 240 volts, or 240 furious bald-faced hornets? We found this while hiking at a state park. Enjoy…

If its a hornets nest... its the BIGGEST ONE I HAVE EVER SEEN!

Looks like a bottomed out can...

I wouldn't go near the area, nevermind go up the pole.

Ok.... The hornets nest is a bad thing....

But why is there only one primary connected to that transformer... Am I missing something here???
Is that doo-hickey up there near the pri connection that looks like some kind of support, actually some kind of pri grounded phase?

Losta — It’s called a one-bushing transforemr. H1 is the top connection, and H2 is tied to the can. It must me used with multigrounded-neutral distribution, and primary windings are grounded-wye.

[A lightning arrester is included on the one-bushing transfomer.]

Randy, that "doo-hickey" is part of the pole's guy wiring.

Actually, If these little (?) critters are someplace where they aren't bothering anybody, I don't mind having them around. They eat flies for a living, and there won't be any for a 100 yard radius around the nest. I have a friend that lives in a wooded area, and there is always a hornet nest somewhere in the vicinity. The neighbors can't sit outside for the flies, he has no problem. He leaves them alone, they leave him alone. What's cool is watching one of these guys chase down and grab a fly on the wing.

Granted I wouln't want to be the poor lineperson who has to reset the switch feeding this one. [Linked Image]

Yup, this was definitely a hornet nest. As Trainwire said, they're not too bad to have around. I've seen them land on top of a daddy long-legs, chew around their exoskeleton, and eat out the insides! Check 'em out:

A great lesson on electricity AND entomology! That's what I love about this job; you never know what you'll find in an old panel, jbox, CT cabinet, etc!
