Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold. Red PEX pipe carries hot water. Blue PEX pipe carries cold water.
Can you run Romex next to PEX?
Member. Romex is rated for 90* C it can touch, it can take the heat. Just don’t share the same holes with romex with any type of PVC or PEX because of expansion and contraction in those pipes.
How do you tie a pull string to a cable?

Yeah just put a hole a few inches in on the PEX and put tie wire through it and pull it in like electrical cable. Soap it up good on the way in. It should go a long way if your strong enough.
What is difference between Thhn and THWN?
The main difference between these two standards is their maximum temperature in wet locations. THWN has a maximum temperature of 90°C in dry and wet locations, whereas THHN wire can only be used in temperatures as high as 75°C in wet locations. However, most of these wires, so you can use THHN and THWN interchangeably.
Is used to pull wires into the conduit or raceway?
fish tape
The most commonly used tool for pulling wire through conduit is fish tape, an electrician’s tool with a long, flat metal wire wound inside a wheel-shaped spool.
Can you pull Romex through conduit?

Can you run electrical wire through PEX pipe?
Don’t use PEX, it’s not rated for carrying electrical wires. You can get flexible metal conduit that’s way more flexible than PEX; or you can get PVC conduit that’s similar to PEX in flexibility and that you can seal from the elements.
Can Romex touch water pipe?
Registered. All metal water pipes in a home are bonded to the panel neutral bar and ground rod. A frayed wire will not electrify the pipes, the pipes are the ground return and the breaker will trip. Romex should never be run through concrete without a mehanical sleeve of PVC or conduit WITH bushings on both ends.
Can you run a water line and electric in same trench?
If trench is to be a joint trench (shared with other utilities) the following separations must be maintained: 24 inches between gas and electric lines. 12 inches between water and electric lines.
How deep are buried electrical lines?
24 inches
In addition, National Codes dictate the depth, below ground, these lines must be buried. Some low voltage underground circuits could be as shallow as 18 inches, while most higher voltage circuits will be deeper than 24 inches.
How deep should a trench be for a water line?
The general depth of underground water pipes is 12 inches below the frost line in your specific geographical area.
How deep does underground wire need to be buried?
Bury in the Ground: Dig 24 inches
There’s one restriction: It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground. Burying the cable 24 inches requires more digging, so this method only makes sense if you have easy-to-dig soil or are renting a trench digger.
Can you bury wire without conduit?
Direct Burial rated wire is approved to be run in the earth in accordance with the National Electric Code (NEC), usually without the use of conduit to surround it. The combination of the insulation material and its thickness keeps out moisture and other harsh factors to protect the wires inside.
Does underground wire have to be in conduit?
Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
Can you bury Romex without conduit?

Is it OK to bury Romex wire?
Romex cannot be used in the situation you describe as buried conduit is considered a wet location. You must use conductors such as THWN. Also, minimum burial depth for conduit (PVC I assume) is 18″, unless you run rigid or IMC, in which case you can go a minimum of 6″.
What happens if Romex gets wet?
In most homes, ROMEX® wire is used for electricity, where the copper ground wire is wrapped in paper and then, in turn, wrapped in the live and neutral wires. If this wiring is exposed either through a break in the plastic coating or even at the socket, the moisture can be soaked up by the paper, creating rust.
