putting control relays in a panel

[aaron4998]

what are the violations and the code article to support this and is there a violation with bringing 208 volt into a 480 panel if so what is the article for this as well

What kind of panel is this?

That equipment is not in a 'panel', it is in a cabinet and I see no violaton.

I predict that a NRTL will be coming by soon.

I am not aware that Article 312 requires cabinets for dry locations to be listed.

I also do not think that ugly or unusual means dangerous or code violation.

 

[volt101]

In order for the inspector to approve the installation regardless if in a dry or wet location he/she must follow 110.3.

110.3(A) basically requires destructive testing. How else does the inspector test for heating effects under normal conditions of use and also under abnormal conditions likely to arise in service? How does the inspector test for arcing effects?

110.3(B) is just so much easy for the inspector. He/She can keep their feet up on their desk while some other inspector does their work.

Does that thing have a UL listing

A company I worked for rewired a large NY area newspapers presses a few years back. Every one of these enormous Goss presses has a control panel similiar to the picture shown. We wired them exactly as the Goss engineer instructed and all thought there must be something wrong with allowing it but apparently...

As long as the unit is a Control Panel, is listed for use as such, and labeled with the two voltages it is perfectly legal.

I see a bunch of devices installed in a box. If this requires NRTL testing, so would putting a relay or a contactor in a box that it didn't come it.

If a relay, contactor, timer etc is sold without an enclosure (cabinet), and I install it in an one, I have to get it tested? Ridiculous.

Nothing wrong with this picture off the cuff, albeit a little messy, IMO.

In regards to the voltage of the conductor insulation, 300.3(C).

In regards to the listing requirements for this type of installation, there is no listing required, yet. Check out Article 409.
Also UL has a Standard for this - Standard 508

Looks like a control panel. On the first blush I see no violation.

Poor design and workmanship.

Should use a terminal strip to reduce the "spaghetti" factor.
Fuses should be grouped together.
The protective ground is suspicious as to whether it is bonded as it should be.
I don't see a subplate.

NFPA 79 probably applies better than NFPA 70 for this application but is not required.

this is not a control cabinet

This install was done in the top of a 480 3 phase 42 circuit panel

we use to get them all the time in California.
that was the way to do warehouse Lighting.
You buy that can extension and it came with a back plate.

 

[nakulak]

be nice to see a better pic of the whole thing

 

[iwire]

Here is one I added for some lighting control.

 

[RETRAINDAILY]

here in Arizona they will not let you even built a lighting contractor box any more unless you are a 508 shop. other wise you have to buy a premade job.
He passed me but they are starting enforcing that more.
From what the Phx. inspector has said
