An average day

A lot of rocks under, around and over the piping, no good. I see tape over the openings, do you require a pressure test on pool piping as required in the ISPSC?
The pipes that have tape originate in this device. I don't know what it does. It is not part of the pressurized system. While the process pipe is always under pressure at the pre-gunite inspection, we do not inspect it as it is not associated with a potable water system. CPC prohibits pressurizing plastic pipe with air.

300.34 Conductor Bending Radius. The conductor shall not be bent to a radius less than 8 times the overall diameter....4/0 wire is 5/8"....5/8" x 8 x2 = 10" diameter circle.
The above section is in Part II of Article 300, and Part II only applies to conductors over 1000 volts. The NEC has no numerical requirement on bending radius of individual conductors under 1000V. Article 314 does have a requirement on the bending space to leave at terminations in cabinets.

Cheers, Wayne

You are correct.
 
With that panel design and a large number of cables entering it, there is no other way except a large Romex® connector to bring them in
This connector will let you bring (6) typical NM cables into a single 3/4" KO. Given the extra width, you might only be able to use a single row of KOs on the top the cabinet:


Also, per this chart, Arlington NM844 will let you bring (10) 12/2 cables into a 1-1/4" KO.

Wayne,
Is there a listing associated with the NM844? If the answer is yes I would suppose that the (10)12/ 2 would be legal. If there is no listing it is up to the inspector. That type of fitting is prone to loose cables.....The cable is not secured well. Toss in one round cable and it goes away....include a 10/3 and where are you on the chart? It is plastic.....The smarter electricians use metal fittings....

If I may ask, how long has it taken you to get through the Average Day thread?

Well, all I can easily say is that the Arlington catalog page shows the UL listed symbol next to the product:

Do you know of a metal, listed fitting that would let you bring 10 NM cables through a single KO?

I think I started over a week ago, reading it on and off. I skimmed a lot of the text, mostly focusing on the train wreck pictures.

That is one thing about this thread, a LOT of train wrecks.
 
There's a couple of similar threads...smaller.... The pictures start out polluted with a water mark.

Oh, and welcome to the forum.




"Do you know of a metal, listed fitting that would let you bring 10 NM cables through a single KO?"
No. To be honest, I really don't know a whole lot about electrical stuff like fittings etc. And more....When you brought up the mistake that I made with wire bending radius I went looking for a code that would help and found none. So there I was again, shooting from the hip. Oh well I had the right idea.

I have been writing a story that includes the solar industry. Part of that is the habit of installing solar where it doesn't belong. At noon yesterday I came across this. It faces Southwest.
