True but If I am going the length of the house with several cables I am not doing all that drilling.Actually, though holes provides a better support for things like that...on the bottom you only staple every 3rd joist, and you can't hang heavier things on the NM
I remember them for receptacles and switches on block basement walls, and the cables were always stapled to the face of the board, not the edges.
If that is the case you do the hole basement with two boards 15' apart !
then you need to run them in some sort of chase, on running boards or in raceways. Ampacity adjustments do apply if you don't maintain spacing of small enough "bundles" in any of those methods.
Some sort of chase. is like saying some sort of wire. the more i rescarch this the less i know. some one from the nec should address this !
The conduit is cheap and easy though. This in 1 1/2. That is room for a bunch of residential circuits. And if you want to add a circuit it's big enough to just push a piece of NM through. How large is this circuit?
It doesn't work that way...you can get a Formal Interpretation from the NFPA on a rule in the NEC but it is a long process, many months, and you must submit your question in a way that it can be answered "yes" or "no".
At 5 NM cables in that PVC, you need to use 12 AWG for a 15 amp circuit and 10 AWG for a 20 amp circuit.
can you post a post a pitcher please ?
I can tomorrow if I remember to take one
My ahj is a moron . like many others !
I didn't factor in fill because I don't know what the circuit/circuits are. But even at 2 1/2, it's still cheap enough
I could describe possibly several hundred ways you could build some sort of chase or I could go pretty basic and mention building a chase out of wood, metal, plastic, maybe masonry?
Not talking about fill, talking about the required ampacity adjustment for more than 3 current carrying conductors. At five MN cables in the raceway, you need to use 12 AWG for 15 amp circuits and 10 AWG for 20 amp circuits, when NM is installed in a raceway for more than 24".
That's good to know. I've done it but never with 5 circuits. It's always me cleaning up a NM mess someone did in a commercial structure or a barn and I'm just sleveing the existing conductors.
