Can you run two wires one hole
When pulling multiple wires through one hole be very carfull not to cause a friction burn on the other wires in the hole.
Regardless of whether it is Code or not, you should only feed one wire through one hole.
Drill a separate run of 3/4″ holes for each wire your run, even if they run parallel to each other..
Is it OK to zip tie electrical wires together
Yes you can. But allowing natural air cooling is important so zip tying a bundle of cables together may mean the inside cables run hot so cables should be tied together in a manner to allow adequate cooling by natural air flow.
How many wires can you bundle together
Bunching together is a serious issue. For instance, in EMT conduit, you are allowed only 9 active conductors regardless of pipe size, unless you derate (use larger wire than normal). That means four circuits, or three 3-phase circuits.
Can I run wires under floor joists
Code says that you may not staple wires to the bottom of a floor joist unless the wire is 6-2, 8-3, or larger. Smaller wires must be run through bored holes or be attached to a running board. … Don’t use wire runs as a clothesline.
How big of a hole can you drill in a 2×8 floor joist
Keep the hole at least 2 in. from the top and the bottom if it’s a dimensional lumber joist. The hole cannot be larger than one-third the depth of the joist, so the maximum hole size for a 2×12 joist (actual size 1-1/2 x 11-1/4 in.) is 3-3/4 in. diameter—plenty big enough for running cable!
How many 12 2 wires can be stapled together
Our rule of thumb was always one wire per staple and two wires max side by side. if you need to put more than two wires use what we call stack it’s. Its a plastic nail on wire holder. and you can stack about 6 to 8 wires maybe more if you can fit them there.
How big of a hole can you drill in a 2×4
Drilling. Any stud shall be permitted to be bored or drilled, provided that the diameter of the resulting hole is not more than 60 percent of the stud width, the edge of the hole is not more than 5/8 inch (16 mm) to the edge of the stud, and the hole is not located in the same section as a cut or notch.
Do electrical wires need to be stapled in attic

How many wires can be in a 7 8 hole
four cables7/8′ would be a better choice there. Bottom line for running cables is before derating affects “standard” ampacities for #14, #12 or #10 XX/2 or XX/3 cables you can run up to four cables in a hole or bundled. The key here is nine CCC’s, or current carrying conductors (hot and neutral).
How far apart should Romex be stapled

Can you run multiple Romex wires together
There is no limit. Some might say this is bundling, but I seriously doubt the wires are tightly grouped together for more than 24″ in this instance. As many as you can without damaging the jackets of the cables. You need to address derating issues when stuffing holes with cables.
How many Romex wires can be bundled together
If all of these cables are 14/2 romex serving general lighting/receptacle loads, then you can bundle 3 together at most before you have to derate them.
Is it OK to bundle Romex
No, but it certainly could be considered “lack of maintaining spacing” if the front cables are not separated from the back cables to allow for air flow. … If all of these cables are 14/2 romex serving general lighting/receptacle loads, then you can bundle 3 together at most before you have to derate them.
How many wires can go under a staple
Secure only one cable under each fastener, in most cases. Sometimes it is permissible to secure two 2-conductor (plus ground) cables under a single staple, for example, but it is preferable not to double up cables. It is not permissible to secure more than one 3-conductor cable under a single staple.

Can you staple Romex to bottom of joists
2 Answers. You can run cables across and under the joists. If you do though you must install them on running boards for protection. Typically it is just easier to drill.
How many wires can go through floor joists
two cablesRe: Running Wire through Floor Joists Generally it’s acceptable to run two cables in parallel, and together through lumber. More than two, and you technically derate the cable (electrical heat dissipation).
