225.31 Outside circuits

225.31 Disconnectiong Means.

Are they talking about FEEDERS, Branch Circuits or all of the above?

If I run a 12-3 uf to a outbuilding, 1 ckt to a gfi receptacle, 1 ckt for lighting do I need a disconnect for that receptacle circuit?

 

[bphgravity]

Yes, all the above.

 

[Bea]

225.36 states disconnect must be service rated or fall under the exception

 

[Jim W in Tampa]

So is that receptacle not a disconnect ?

So is that receptacle not a disconnect ?

Nope.

You won't find a service rated receptacle or an exception that allows a receptacle to serve as the disconnecting means for this application.

Nope.

You won't find a service rated receptacle or an exception that allows a receptacle to serve as the disconnecting means for this application.

What do most people find easier, when wiring a outbuilding with only a multiwire branch circuit, just a 2 pole switch??? I have to confess I've never installed a disconnect for a receptacle circuit before... always just assumed it was okay since I was taught that way from more than 1 contractor...

A couple toggle switches would do just fine.

George wouldn`t you need some type of handle tie to break both conductors on a MWBC if toggle switches are used ???

IMO the rational for requiring a handle tie is so that if one part of the MWBC is de-energized there is no possibility that the other part will have a neutral load from the energized part.

Yes, 225.33(B) requires that.

 

[allenwayne]

Thanks Bob I thought that was the article.Do they make a handle tie for SPST switches ???? I`ve never seen them.

 

[iwire]

.Do they make a handle tie for SPST switches ???? I`ve never seen them.

I've never seen one either.

I wondering why I would not just use a two or three pole switch?

 

[allenwayne]

225.33 B allows a common handle tie on single pole switches........Would the code panel allow something to be required that isn`t manufacturered ????

Oh that`s right the new afci protection requirement isn`t available also.........

I guess they would after all...................................................

 

[stickboy1375]

Yes, 225.33(B) requires that.

Does anyone understand the reasoning behind this article? I've never seen/heard of a multi switch handle tie, so why not just say I need a 2 or 3 pole switch??

How about a [simple double-pole switch...]

 

[iwire]

How about a simple double-pole switch...

Well yeah...

But read 225.33(B) it talks about handle tying single pole switches as well as CBs

 

[DaveTap]

225-38(d) requires indicating, but 225-36 exception allows 3-way or 4-way snap switches... Anyone have an indicating 3-way or 4 way snap switch in stock?

 

[Jim W in Tampa]

Either 2 pole or a 60 amp pull out.Why is a receptacle or switch ok as disconnect for garbage disposal but not here ?Its the same switch.

One of us has got to get up to speed...this whole daylight savings thing messes with my head

Why not,they require afci breakers and none that do whats required have been made yet

I guess I am still in the slow lane as I ain't getting it.
