bonding jumper

[dingokangaroo]

I'm a lead electrician and was told by my forman to put a bonding jumper on a panel that is not the first means...it is the second..the first is already bonded. i belive i should not do this and informed him as such. am i correct in this assumption as he states i have read art.250 incorectly

Is there a transformer between the two panels?

[dingokangaroo]

no. negative. there is not.

Well, then you are right. Have the lead man read 250.24 through 250.28 taking special note of 250.24(A)(5)

(5) Load-Side Grounding Connections A grounding connection shall not be made to any grounded conductor on the load side of the service disconnecting means except as otherwise permitted in this article.

he claims that I am misinterpeting the code. thanks for the input

 

[roger]

I apologize for referencing the "lead man" I meant to say "forman", had someone talking to me while I was typing.

thats ok..he chose me for the job of lead yet when i try to help he usually acts like most of us......"I'm right and thats that"....attitude. lol

 

[dingokangaroo]

no there is not a transformer between Don.

I agree with Roger. [250.24(A)(5)] is straight forward unless there is another separately derived supply involved. The subpanel is a fourwire with isolated neutral bus if that's the configuration.

 

[dingokangaroo]

correct. I have a ground from the disconnect to the panel yet he insists on the bond and is using the nuetral bar to land the ground and the nuetral. 4 wire single phase

Just walk in tomorrow and tell him he is wrong, no need to go on here, we agree with you.

Print this thread and hand it to him, he can come here and confront us with his argument as to why he thinks he is right.

Well, you are misinterpreting "the code". You know, the one that's in his head.

You're doing just fine by the NEC, however.

 

[gndrod]

Ask for a reason and let us know.

My wife is fond of doing that.

That's that's why sometimes I write write words twice or skip some.
