Mechanical Lugs and work space

[aelectricalman]

Can someone please point out where in the NEC 11 does it state that mechanical lugs (like ontop of a capacitor) must be accessible and not consealled. I know its there, just dont know where. Thanks

I don't think there is anything specific to capacitors or mechanical lugs.

I forget where it is but connections are generally required to be accessible.

I think there is something specific to equipment (not specifically caps) but since these are lugged down connections, you can't stack them on top of each other and encase them down in a box that is not meant to be open. Thats my actual concern.

I am having a hard time understanding your usage of the word "encase" in this context, or the phrase "not meant to be open".

If its inside the equipment then the NEC probably doesn't apply to anything other than line and or control connections. Most of the equipment I've seen they clip those connections on, sometimes put on a rubber or plastic cover and stuff the cap in the deepest cavity they can find and screw it in. Then they install some immovable object in a position to cover the screw head...

Are you saying these capacitors are installed in a way where it is difficult or impossible to open the access covers, or are you saying something else?

314.29 comes close but probably doesn't apply, 110.3(B) maybe applies, depends on what the instructions say.
