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.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?
Does anyone require a pressure test on the pool piping as required in the ISPSC?
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.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.
You are correct.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.

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: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

Bridgeport
Since 1925, Bridgeport has led the industry with US-made fittings, built from our principles of innovation, quality, outstanding service and rapid delivery, a tradition we maintain as part of the NSI…www.bptfittings.com
Also, per this chart, Arlington NM844 will let you bring (10) 12/2 cables into a 1-1/4" KO.

Well, all I can easily say is that the Arlington catalog page shows the UL listed symbol next to the product:Is there a listing associated with the NM844?
Do you know of a metal, listed fitting that would let you bring 10 NM cables through a single KO?It is plastic.....The smarter electricians use metal fittings....
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.If I may ask, how long has it taken you to get through the Average Day thread?
That is one thing about this thread, a LOT of train wrecks.Well, all I can easily say is that the Arlington catalog page shows the UL listed symbol next to the product:

I can't get the link to open.
Hmm. I can't seem to upload an image. Not sure what to do ....I can't get the link to open.
