What ART. states that I can make a splice in a ATS if of the same power source?

There is none, but there is nothing that says you can not. :smile:

Thank you BOB. I have an engineer saying I cannot make a splice in
a Transfer switch.

 

[Karl H]

I need to back that up with a NEC art. He also said I can't run LT unsupported
for 3 feet.

Defensive code art. might be 312.8.

See 350.30 for the LT.

Yeah, 312.8 is what I quoted. But, as Bob said, "It dosen't say you can,and
it dosen't say you can't."

Karl, I know there's more to the story than a splice ?

Nope, just a splice.

The burden of proof of non-compliance is upon the inspector.

Your right, but I have a engineer saying, "You cannot make a splice in
a ATS." I say, he is wrong. Thanks for the help guys.:smile:

It's a switch, unless the AHJ can make a stand on head dissipation, don't see where he has a leg to stand on. Call the manufacturer of the ATS and have them fax a copy to you of something saying you can do this {makes it a 110.3(B)}.

I always assumed that if it were just splicing the 75% is however much will fit within reason into the box/area that remains. Sounds like the AHJ is is inspecting on how he feels, not what the law says.

Part 2 is it worth if it you win the battle, but lose a war? Battles have to be chosen carefully against future activities...

Engineers are smart about theory, not code. Drag the inspector to the thread.

This isn't a inspector, it's even worse ,an engineer <Just Kidding engineers on
this forum>

 

[Rockyd]

WOW! I'm sorry Karl!

If he wants to pay for the change, and it won't look stupid, change it. Sometimes the money gets cheap in comparison. Not like I haven't done it "the stupid way", to keep peace on a project before.

Does it say in the spec or on the drawings, No splices in the ATS?

 

[benaround]

Karl, What exactly is the splice ? Is it 2 or 3 conductors ? What size wire ? what is it feeding ?

Just read the specs and no mention of splices anywhere.

I talked to the foreman that made the splices and he said it was three
conductors, 3/0, and it was feeding a chiller that needed to be relocated.
