Adding a safety switch...

[marrt]

I'd like to add a safety switch before some of my outlets. This will allow me to "lock out" some machines. If this were 110, I'd probably add a junction box after the switch with a pigtail to connect the two outlets. Is this the preferred method with 220?

I would avoid the junction box....the less connections, the better.....as far as I know, it's legal (code wise).

The shut off will have nice big terminals.....I would do all of the connections in there....wire is cheap in realtive terms.

But... The connectors will not be rated for 2 conductors per terminal, & avoid GE / Goverment Electric safety switches they are a poor design.

This is what I assumed as well. I could probably cram a pig tail in the box, but it would start to get a little crowded (and may not be allowed by code?). Although this is technically a "pole barn" and does not have to be inspected, I'd like to stay code complient. I'm pretty conservative when it comes to electrical stuff.

Norcal, do you have another box you would recommend? I was planning on using a GE TG4322 from superbreakers.net (they're pretty cheap). I have 5 of these to do, so I want to get it right. Also, I'm using these stricly as a switch...don't care if they have a breaker or not.

My choices would be but not in any order are: SQ D, Cutler-Hammer, or Siemens safety switches, if you should decide to use GE, make sure all fasteners are checked prior to energizing, otherwise a cooked switch could be the result. (It is wise to check everything no matter who the manufacturer is).
