huh? the OP is in wisconsin
What reduced neutral? All 3 look the same size.
I was poking fun because his panel is upside down from the normal orientation. That was all...bad joke I guess
First, the neutrals and grounds are on the wrong sides ! Who cares if they have plastic standoffs if only one is bond to the enclosure ?
I ASSUME the "2" means "to", correct ?

The panel is not "upside down" it's been correctly done instead of stupidly putting the main lugs/main breaker at the top when the feed enters from the bottom.I was poking fun because his panel is upside down from the normal orientation. That was all...bad joke I guess
The black strap is an insulated jumper connecting both insulated neutral blocks together. As it is configured now, there aren't dedicated ground bars.Referring to this image in the FAQ

Will you please cite the code reference?
If it was permitted, I'm guessing you can look it up by permit? In the county where I live, you can view any permit for your property that was pulled for work. That may tell you when it was installed at least...
He already said it was installed 10 years ago in post #13. When wouldn't matter without know which edition of the code was being used then. Some permits might give that information, but the permits I pull don't, it's just something we are supposed to know. My guess is that in 2016 they were on the 2014 or maybe still the 2011. The odds of being on the 2005 or older (prior to the 2008) in the year 2016 are pretty slim, that's why I said it's a long shot.
And there might not have been a permit at all and the old timer that did the install did it the same way he's been doing it since 1964 when he started.
I agree. There are more outbuildings with three wire feeds out there than there are four wire feeds. Adding the equipment ground would probably be way more work than it's worth even though it's technically not right.
NO! You can only do that if there is a separate ground wire pulled back to the main panel. There won't be anything to carry fault current causing a breaker to trip. The intent of the ground rods is to shunt lighting; while they may be capable of clearing a short, they can't be trusted to do so.
3-wire feeder VS 4-wire feeder
First topic for this sticky is one that is beat to deathevery weak- the 3-wire vs 4-wire branch feeder.
The following pics are here to help those who are visual learners.
3-wire feeders to detached structures that had no other parallel metallic pathways(eg. conduit, water and gas piping, communication cabling, etc.) were allowed up until the 2008 NEC code cycle.
From then on, 4-wire feeders have been required.
4-wire feeders to panels in attached structures have always been required.
3-wire feeder to DETACHED building(no longer allowed as of 2008; existing feeders are grandfathered in as long as there are no parallel metallic pathways between the buildings):
Wire looks like URD with a reduced neutral. But, I stand corrected. Apparently a reduced neutral is allowed.
There is no upside down unless the main has to be switched verticallyI was poking fun because his panel is upside down from the normal orientation. That was all...bad joke I guess

OP said it was installed 10yrs ago so that wont fly
The code change for this was 2008 NOT 2011
