Default Third Party Inteterlock Kit

That are sold on http://www.interlockkit.com/ are UL tested but not UL listed and was told by a buddy of mine that a inspector could fail them with no questions asked? Just wondering if anyone here ever had one of these installs shot down?

The inspector would have to pull something from the NEC that requires that they be listed. I fail to see that requirement. Remember, after all, the UL is just a company. Not the government.

It could simply be that they are UL tested just to prove to some hard ass inspectors that they have been examined by the UL. They probably aren't listed because I can't seem to find a UL White Book category they'd fit in.

The inspector should ask questions before he makes himself look like an idiot.

Some inspectors reject all interlock kits because they are not listed as transfer equipment and 702.5 requires transfer equipment. In my opinion the interlock kits provide the require functions of manual transfer equipment, but not all agree.

How could SOME inspectors reject it? It's either code compliant or not?

Don, wouldn't the exception apply here?:



(1) Manual Transfer Equipment.
Where manual transfer
equipment is used, an optional standby system shall have
adequate capacity and rating for the supply of all equipment
intended to be operated at one time. The user of the
optional standby system shall be permitted to select the

load connected to the system.



Exception: Temporary connection of a portable generator
without transfer equipment shall be permitted where conditions
of maintenance and supervision ensure that only
qualified persons service the installation and where the
normal supply is physically isolated by a lockable disconnecting
means or by disconnection of the normal supply
conductors.

I was told our state requires 3rd party listing or AHJ approval for all electrical equipment installed by my continuing ed instructor.

That exception never applies, in my opinion, to a dwelling unit and it only applies to the connection to a portable generator.

Based on the code wording all inspectors should reject it. The device is not "transfer equipment".

The inspectors that accept it understand what the code rule is asking for and permit these types of devices because the provide the function of transfer equipment even though they are not listed as such.

Seriously: who here pulls a permit for such a 'project'?

Not that I'm afraid of permits- But.... after the running around and scheduling inspections.... add 2 hrs-Real time- to the project-
You lost any and all profit.... And....

The inspector would probably be a Tadd irritated.

Messed up their lunch.......

Looks good... but why did you put the PB30 inside the house/ garage?

I know it's rated for indoor/ outdoor use but I figured it's best to put it outside so no one would ever start the generator indoors.

What do you think?

I had a extra so used it. As far as putting it outside this particular customer actually wanted it inside? The panel is about 3 feet from the door and explained that the reason you bought a 20 foot cord is to put gen outside.

I also did one about a month ago that was actually in the basement. I did not have it inspected do you think it would of passed? The HO had a 40 foot cord and window close by.

Does UL tested mean that they passed?

It should have passed. The PB30 and PNB30 are rated for indoor/outdoor use. It's in the paperwork in case you were wondering.

I saw the Cutler-Hammer CH EmGen prewired panel for the first time today. It's a lot like the Reliance brand except it's not a piece of crap like Reliance breakers are. The only thing I didn't like was the inlet built-in to the panel.
