Bob I'm not familiar with the UL white book. what jurisdiction does it have in with respect to the NEC.

If the UL white book does not match up with how we use a listed product you should get hit with 110.3(B).

Looks odd, why do the feeders come into the bottom of the switch??
The fuses would be hot all the time, I thought that the feed lugs where always on top and the load on the bottom.

They look to me like they come out of the CT can and hit the line side(top) and the load leaves the bottom.

Is there a pic of the service entrance conduit into the CT can?

I was thinking the same thing when I first looked at it but if that is so it also seems odd that the top lugs on the CT would be the load connection

Remember they used to be - now you must be nostalgic, or throw them over the border into Canada for them to be rain tight....

I think I figured out why the nuetrals run seperate. It was probable an afterthought. They may have originally called for 480 3 wire and then needed 480v 277 4 wire .
Couldn't they have fit the nuetral in the original conduit. Even downsized the wire.

Not without pulling the original wires out, and they probably struggled to get them in... ;) :grin: That installation is a joke...

Hey is there a problem using parallel conductors. When we were doing a lot of commercial work we never pulled 500 cu. My boss thought it was tooo much trouble.
