Hey All. Is there any rule disallowing the SEC and ground wires to enter the main service panel through the same hole/under the same connector? I usually see them coming in separately.
You are correct, they should not be in the same connector. For that to be code compliant the SEU cable connector would need to be tested and listed for use with the two GEC’s as shown in the photo.
You’re welcome. If that connector were over-tightened the bare GEC’s could possibly damage the SE cable.
