Ct can bonding

[RATLIFF]

I had a student tell me that the electrical inspector made them bond the neutral in the ct can to the can and also bond the neutral in the main disconnect.
In my experience this would be a violation
can i get some help in understanding this situation?
Or is the inspector in error
thanks

If you look at any meter can, the "neutral" lug is bonded to the can. Seems more for convenience sake than any other. I have had a hard time understanding all this as well but it is an acceptable practice.

Everything that is to be grounded on the line side of the service is bonded to the neutral. In the service equipment, the grounding conductor is derived and the main bonding jumper is connected between the grounding conductor and the neutral. :smile:

I agree with Charlie. This is one time where you are permitted to have parallel paths for the neutral current if using a metallic raceway.

You may be referring to new ones but I've seen plenty of old ones with isolated neutral lugs.

One of the factory CT cans used in this area comes with stud-kerney installed for bonding to the neutral.

Around here even if the neutral came in the cabinet isolated the POCO would require it to be bonded to the can.
