Service Conductors

[Bird58]

Can the unprotected service conductors coming from meter can pass through same gutter as the conductors leaving the main disconnect. It looks as 230.7 says no. But not sure if that is the right code

Is the enclosure in question an Article 366 Auxiliary Gutter, or an Article 376, Wireway? The answer is yes if it is an auxiliary gutter, but no if it is a wireway. Auxiliary gutters are pretty rare. Most everything an electrician calls a gutter is really a wireway.

Thanks. It is a wire way.

Ok. Read everything. But still don’t see code or definition where the unprotected service conductors from utility meter can not be combined with protected conductors from main disconnect in same wire way

I think what Don was saying is that a wireway is a raceway and therefore 230.7 applies. An auxiliary gutter is not a raceway so it would be allowed. I'm sure Don will correct me if I'm wrong.

What Dennis said, plus 376.2 Definition makes it clear a wireway is a raceway.

An aux gutter is sort of an extension to a cabinet, you can have line and load conductors in a cabinet, we do that all the time in cabinets where the service disconnect is housed.

For me a picture was worth a thousand words

Auxiliary Gutter-- sort of like an extension ring

In general if the enclosure is connected to another enclosure using nipples, it is is a wireway and not an auxiliary gutter.

Good to know. I assumed this one had an open bottom.

If you determine that it would be code compliant, also check the design criteria for the utility. Austin Energy and CPS (San Antonio) expressly prohibit it.

How about a horizontal gutter with buss bars that feed metered main panels, what is that called ?

I think that is generally called a "bussed gutter"

Thank you ...

I have heard it called a "bus duct".

With POCO's it isn't so much protected vs unprotected as much as they simply don't want metered and unmetered mixed in anything except for the meter socket to help prevent theft of service.
