Re: Clamp needed?
I believe there should be a "red head" bushing, just like the two on the right.

Re: Clamp needed?
THHN to be exact. I would guess they are running thru conduit behind the drywall which is typical.

Re: Clamp needed?
For clarity on Jerry's initial response:
Jerry, while the answer to "Should these cables be clamped where passes through the knockout openings into the panel?" is YES.... does your response (IF they WERE cables) suggest they would NOT have been properly clamped even with this set-up ?
Or, since there are cable clamps present (bottom section not visible due to in-wall mount) would this suffice as is (if they were cables passing through)?

Re: Clamp needed?
Sorry, I concede that there may not be "cable clamps" present, but that a "raceway" is more likely present. The round wingnut made me jump to conclusions that a "cable clamp" was present.

Re: Clamp needed?
Jeff,
These are single conductors entering conduit. It seems your question was actually something like "should these be protected from the metal edge of the conduit fitting?" The answer is yes, and there are several products that can accomplish this. Let your client know they will need an electrician.

Re: Clamp needed?
Randy,
I am going to make an assumption that the raceway is either emt or what we here call greenfield and enters the panel trough a listed fitting. Such a fitting is listed for use without any type of "antishort" bushing.
Making another assumption that this is a residential panel and therefore single phase, why is there a black, red and blue conductor along with a green ground and no neutral? Also what is that black "blob" entering the panel through the fitting just above ( behind) the conduit fittings?
