What' this about? The last guy quoted the Code to the owner citing that the C/Bs were not "within sight" of the machines because of the doors on the loadcenters, hence he installed all these EXOs.
Fusible with 30A fuses, fed by 20A breakers.
Now, I've gotta fix it.
Any ideas??

The perils of taking things too literally.... [Linked Image] This lot must have cost a fair bit in materials and labor.

Would there be anything to prohibit you from just keeping all those individual units and fitting them with Never-Blow fuses? (i.e. a shorting link).

What equipment is hung on the load side of all these things by the way?

And where is that disco at the bottom left getting its power from? There doesn't seem to be a conduit running into it from the main panels.

It looks to me like the bottom left disco is taking its power through the small horizontal raceway from the right CB panel (intead of the loop-de-loop like all the others).
There's one thing that really puzzles me about this picture. Maybe you guys can explain it to me. It appears that that there are 11 circuits/pieces of equipment/whatever being served here. The circuit starts in one of the CB panels, then goes to one of the GE discos in the bottom two rows, then each goes to a SqD disco in the top two rows, then on to the equipment being served. Like I said, maybe I'm missing something here, but this just don't add up... [Linked Image]. I wonder if LOTO might have had something to do with this...?

So what does one do with all these extra knife switches? Can they be reused or does it all get chucked in the trash? What a waste.

Do you have to run all new wire & conduit or can you put in junction boxes and just splice the wires together after you take out the extra switches? Obvioiusly the best-looking way would be to just run new pipe & wire...

As for the box on the bottom left of the picture, Mike you're correct.

Look at the TOP LEFT corner and you will see a stump of pipe going into the right side of the closest large panel on its left.

Well...they always say you can never have enough protection.... [Linked Image]

Oh yes, so it is.... [Linked Image]

My eyes were set so much on all those conduits entering the bottom that I missed that length taking the short route!

Electure:
I have to rate this "A". It would get a big "A+++" if the EMT couplings where lined up, and another piece of strut & straps.

If ya have to take it all out, how about a troff around 12" below the top strut, cut back a few EMT's, extend the EMT feeds, and pull in new wire from the panel to the troff.

Since some have decided that those little plastic things are not good enough to "lock out" a circuit breaker, those disconnects provide a good place to lock out a circuit.
Nice workmanship.
Of course, it's always nice to be able to lock out closer to the work site.

This looks like a clean installation, However, I see 2 issues.
1. Line / Load in reverse of the listed method
2. Forign power issue of energized conductors passing through a EXO with the handle in the OFF position.
I cant imagine the AHJ being able to pass this install without correcting these problems.

The reason why "Where's Waldo" popped into my mind is...how easy is it to tell which switch is which? Is the "within sight" rule to protect someone who may be repairing the equipment, or to be able to quickly cut power to the equipment?
