Service Panel Wiring Right? Wrong?

Re: Service Panel Wiring Right? Wrong?

Both wrong. 312.5© Neither fulfills all the exceptions. Not surfaced mounted. Not 18' long. Not sealed at far end. Top panel wires not properly secured. Do I need more?
 
Re: Service Panel Wiring Right? Wrong?

That depends would be the best answer. I see an attempt not to derate the wiring by not "bunching" or "bundleing" the wire together thru the top plate. However, I see other problems as fire blocking and/or draftstopping are being bypassed and/or see potential "holes" in the thermal barrier for thermal envelope of structure. What answers one problem of one code oftens creates other problems in other codes.

What about conduit fill and derating according to 312.5© Ex. G. I would say the install would probably fail there also.

I just remembered that a lot of you guys use I code references, I was using NEC 2008.

However, if he had used a nm connector at the box for each run... what would you cite then?
In the case of the top picture, 334.30, not secured within 12" of the panel.

What are the blue, white, red single wires near the panels?
Looks like RG6, cat 5 and FA.

Sounds right. The RG6 and Cat 5 looked like one pair twisted. New resi combo pack? Do not see a lot of FA here in resi, mostly interconnected smokes with 14/3.

If he did that, as long as this was not ina commercial building, it would make it legal.
 
Re: Service Panel Wiring Right? Wrong?Thanks for all of the replies. I'm not out in the field that often and I've been checking up to see how things are going.
